Description

TECHNICAL FIELD

[0001] The present application relates to an electromagnetic environment analysis system, an electromagnetic environment analysis method, and a storage medium. BACKGROUND

[0002] A device that analyzes an electromagnetic environment is known. For example, a device disclosed in Japanese Patent Application Publication No. 2013-238581 obtains measurement values related to an electromagnetic environment and displays information related to the measurement values. The device causes the information related to the obtained measurement values to correspond to a plurality of divisions that distinguish display ranges, and displays the information related to the measurement values for each division. SUMMARY

[0003] Analysis of an electromagnetic environment is performed in various uses. For example, in an EMC (electro magnetic compatibility) test of an electronic device, it is analyzed from where an electromagnetic wave is generated from the device. In the device described in Patent Document 1, a sensor is moved to measure a signal generated from a measurement target object. The measurement values measured are respectively associated with a plurality of divisions that distinguish display ranges of a display section, depending on positions at which the measurement values are measured. The measurement results are expressed by colors of the measurement values for each division.

[0004] The larger the size of the plurality of divisions that distinguish the display ranges, the lower the resolution of display of the information related to the measurement values. If the resolution of display is low, information related to a local electromagnetic environment cannot be obtained. In a case where a user performs measurement while observing display in a state where the resolution of display is low, it is also difficult to recognize whether measurement values are obtained at a desired density. In contrast, the smaller the size of the plurality of divisions that distinguish the display ranges, the more labor is required to know the overall situation of the electromagnetic environment, and the amount of data of the measurement results also increases. An appropriate structure of the plurality of divisions varies depending on the situation of measurement. In a case where the display ranges are distinguished by a certain size, it is difficult to solve the above-described problems in a trade-off relationship. For example, there is a need to display a measurement result of a rough position at an initial stage of measurement, and then display a detailed measurement result for a desired position.

[0005] An object of one embodiment of the present application is to provide an electromagnetic environment analysis system that can easily achieve desired measurement. An object of another embodiment of the present application is to provide an electromagnetic environment analysis method that can easily achieve desired measurement. An object of still another embodiment of the present application is to provide a storage medium storing a program that can be read by a computer, which can easily achieve desired measurement.

[0006] One embodiment of the present application provides an electromagnetic environment analysis system including a measurement information acquisition unit, a position information acquisition unit, and an image creation unit. The measurement information acquisition unit acquires a plurality of measurement values related to an electromagnetic environment. The position information acquisition unit acquires position information related to a measurement position at which each measurement value is measured. The image creation unit creates an image in which information related to a measurement value is displayed at a position corresponding to a measurement position of the measurement value. The image creation unit includes a division setting unit, a division determination unit, a display information determination unit, and a re-setting determination unit. The division setting unit sets a plurality of divisions that form a display range of information related to a measurement value in an image. The division determination unit determines a division corresponding to a measurement position of each measurement value among the plurality of divisions on the basis of the position information. The display information determination unit determines information related to the display of a division on the basis of a measurement value corresponding to the division. The re-setting determination unit determines whether to reset the plurality of divisions. In a case where the re-setting determination unit determines to reset the plurality of divisions, the division setting unit resets the plurality of divisions that form the display range from a plurality of first divisions to a plurality of second divisions each having a size smaller than that of the first division. The display information determination unit determines information related to the display of the second division.

[0007] In the electromagnetic environment analysis system, the re-setting determination unit determines whether to reset the plurality of divisions. In a case where the re-setting determination unit determines to reset the plurality of divisions, the division setting unit resets the plurality of divisions that form the display range to a plurality of second divisions smaller than the first division. In this case, the display information determination unit determines information related to the display of the second division. Thus, in measurement of a display range, the size of the plurality of divisions that form the display range can be changed. Thus, the resolution of display can be changed in accordance with the state of measurement. As a result, desired measurement can be easily achieved.

[0008] In one embodiment described above, the size of each second division can be smaller than that of each first division. In this case, in measurement of a display range, the resolution of display can be changed from a low state to a high state. Thus, the electromagnetic environment analysis system can display a measurement result of a rough position at an early stage of measurement and then display a measurement result of a desired position in detail.

[0009] In one embodiment described above, in a case where the re-setting determination unit determines to reset the plurality of divisions, the division determination unit can determine a second division corresponding to a measurement position of each measurement value among the plurality of second divisions on the basis of the position information, and the display information determination unit can determine information related to the display of the second division on the basis of a measurement value corresponding to the second division. In this case, since a measurement value corresponding to the second division is determined again, more accurate display can be achieved in the second division.

[0010] In the one mode described above, it can also be that the re-setting determination section determines to re-set the plurality of divisions when at least one of a plurality of conditions is satisfied. The size of each second division re-set by the division setting section when a first condition of the plurality of conditions is satisfied can be smaller than the size of each second division re-set by the division setting section when a second condition of the plurality of conditions is satisfied. In this case, the plurality of divisions of the display range are re-set to second divisions of different sizes according to the conditions. Thus, the desired measurement can be more easily achieved.

[0011] In the one mode described above, the second condition is a condition that is satisfied before the first condition is satisfied. In this case, after the sizes of the plurality of divisions forming the display range are re-set by satisfying the second condition, the sizes of the plurality of divisions forming the display range are further reduced by satisfying the second condition. Thus, the resolution of the display can be changed in multiple stages according to the state of the measurement.

[0012] In the one mode described above, it can also be that a storage section that stores a plurality of division definition tables defining the structure of each division in a case where the display range is divided according to mutually different numbers is further provided. The division setting section can set the plurality of divisions based on the plurality of division definition tables. In this case, even without a special arithmetic process, the resolution of the display can be more easily changed by the division definition tables.

[0013] In the one mode described above, it can also be that the re-setting determination section determines to re-set the plurality of divisions according to an input operation by the user. In this case, the re-setting of the plurality of divisions can be performed at an arbitrary time.

[0014] In the one mode described above, it can also be that the re-setting determination section determines to re-set the plurality of divisions when the number of divisions corresponding to the measurement values exceeds a prescribed number. In this case, the re-setting of the plurality of divisions can be automatically performed.

[0015] In the one mode described above, it can also be that the re-setting determination section determines to re-set the plurality of divisions when the proportion of the number of divisions corresponding to the measurement values to the number of divisions dividing the display range exceeds a prescribed value. In this case, the re-setting of the plurality of divisions can be automatically performed by a simpler setting.

[0016] In the one mode described above, it can also be that the re-setting determination section prohibits the re-setting of the plurality of divisions when the number of times of re-setting of the plurality of divisions exceeds a prescribed number. In this case, a situation in which the re-setting is excessively performed can be avoided. As a result, the detailed measurement of the desired position can be more easily achieved.

[0017] In one of the above-described aspects, the sensor that sequentially detects information related to the electromagnetic environment can be included, and an operation section operated by the user can be further provided. The measurement information acquisition section can acquire a plurality of measurement values based on the information detected in the sensor.

[0018] In one of the above-described aspects, a display section that displays the image created by the image creation section can be further provided.

[0019] Another aspect of the present application provides an electromagnetic environment analysis method including a step of acquiring a plurality of measurement values related to an electromagnetic environment, a step of acquiring position information related to a measurement position at which each of the measurement values is measured, and a step of creating an image in which information related to the measurement values is displayed at positions corresponding to the measurement positions of the measurement values. In the creation of the image, a plurality of divisions that form display ranges of the information related to the measurement values are set in the image, a division corresponding to the measurement position of each of the measurement values is determined from among the plurality of divisions based on the position information, information related to the display of the division is determined based on the measurement value corresponding to the division, and whether the plurality of divisions is to be re-set is determined. In a case where it is determined that the plurality of divisions is to be re-set, the plurality of divisions that form the display ranges are re-set from a plurality of first divisions to a plurality of second divisions each having a size different from that of the first division, and information related to the display of the second division is determined.

[0020] Another aspect of the present application provides a computer-readable storage medium storing a program for use in an electromagnetic environment analysis method, which causes a computer to execute a process of acquiring a plurality of measurement values related to an electromagnetic environment, a process of acquiring position information related to a measurement position at which each of the measurement values is measured, and a process of creating an image in which information related to the measurement values is displayed at positions corresponding to the measurement positions of the measurement values. In the creation of the image, a plurality of divisions that form display ranges of the information related to the measurement values are set in the image, a division corresponding to the measurement position of each of the measurement values is determined from among the plurality of divisions based on the position information, information related to the display of the division is determined based on the measurement value corresponding to the division, and whether the plurality of divisions is to be re-set is determined. In a case where it is determined that the plurality of divisions is to be re-set, the plurality of divisions that form the display ranges are re-set from a plurality of first divisions to a plurality of second divisions each having a size different from that of the first division, and information related to the display of the second division is determined.

[0041] Hereinafter, an embodiment of the present application will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are denoted by the same reference numerals, and repeated description is omitted.

[0042] First, the function and the structure of the electromagnetic environment analysis system according to the present embodiment will be described with reference to Figures 1 to 10 to the drawings. Figure 1 is a block diagram of the electromagnetic environment analysis system. The electromagnetic environment analysis system 1 is a system that performs measurement relating to an electromagnetic environment and displays a measurement result as an image. The electromagnetic environment analysis system 1 measures an electromagnetic field as measurement relating to an electromagnetic environment. The electromagnetic environment analysis system 1 measures, for example, an electromagnetic field generated by a measurement target. The electromagnetic field is generated, for example, by an electromagnetic wave transmitted from a measurement target. The electromagnetic field is not limited to a magnetic field generated by an electromagnetic wave of an extremely low frequency. The measurement of the electromagnetic field includes the measurement of the electromagnetic wave. Hereinafter, measurement relating to an electromagnetic environment will also be simply referred to as "measurement".

[0043] The measurement target includes, for example, various devices such as an electronic component, a substrate on which an electronic component is mounted, and a power supply device. Figure 2 An example of a measurement target is shown. Figure 2 The measurement target 5 shown is a wireless charger. The measurement target 5 includes an electronic substrate 6 and a power supply coil 7. The measurement target 5 supplies power to an electronic device such as a smartphone by wireless from the power supply coil 7 in a state connected to a power source.

[0044] The electromagnetic environment analysis system 1 displays a result image corresponding to a position at which measurement is performed and a measurement result. In the present embodiment, the electromagnetic environment analysis system 1 displays a composite image in which a result image and a captured image in which a measurement target is captured are overlapped. As a modification of the present embodiment, the electromagnetic environment analysis system 1 can not make a composite image and can display a result image on a display of a transmission type. The electromagnetic environment analysis system 1 can be, for example, a head-mounted display of a video see-through type or an optical see-through type.

[0045] In the present embodiment, the electromagnetic environment analysis system 1 acquires a captured image while performing measurement, updates and displays a result image. Therefore, the user can refer to the result image while performing measurement of a desired position. As a modification of the present embodiment, the electromagnetic environment analysis system 1 can also create and display a result image based on a measurement result that has already been measured.

[0046] As shown in Figure 1 , the electromagnetic environment analysis system 1 includes a range determination marker 2 and an electromagnetic environment analysis device 3. The range determination marker 2 is arranged in an actual space and is a marker for determining a range in which a measurement result is displayed or a range in which measurement is performed. "Arranged in an actual space" means not arranged virtually on an image or the like. Hereinafter, a range determined by the range determination marker 2 will be referred to as a "display range". The range determination marker 2 is physically separated from the electromagnetic environment analysis device 3 and is arranged at a position determined in advance by a user in an actual space. The range determination marker 2 has a feature point that can be recognized by the electromagnetic environment analysis device 3 to recognize a three-dimensional position of the range determination marker 2 in an actual space. For example, the range determination marker 2 includes a two-dimensional code or the like having such a feature point. The two-dimensional code includes, for example, three-dimensional position information of the range determination marker 2. The three-dimensional position information is information that can specify a three-dimensional position of the range determination marker itself. In other words, the range determination marker 2 has information that can specify a position at which a captured image is captured in an actual space and a relative position of the range determination marker 2. If the electromagnetic environment analysis device 3 can recognize a position of the range determination marker 2 in an actual space, the range determination marker 2 is not limited to this manner.

[0047] In the present embodiment, as shown in Figures 3 to 5 , the range determination marker 2 includes a plurality of range determination markers 2a, 2b. Each of the plurality of range determination markers 2a, 2b is arranged at a position determined in advance. In the present embodiment, each range determination marker 2a, 2b has three-dimensional position information by a two-dimensional code or the like. Each range determination marker 2a, 2b, although not having information that can specify a three-dimensional position as a single body, has information that can specify a position within a captured image. In Figures 3 to 5 , two range determination markers 2a, 2b are arranged around the measurement target 5. In the example shown in Figures 3 to 5 , as described above, the measurement target 5 is a wireless charger. The measurement target 5 performs an operation in a state in which the smartphone 8 is arranged on the power supply coil 7. For example, a display range RA in which a measurement result is displayed is a rectangle, and the vertices of the diagonal of the display range RA are determined with the two range determination markers 2a, 2b as a reference. The top left vertex of the display range RA is determined by the range determination marker 2a, and the bottom right vertex of the display range RA is determined by the range determination marker 2b.

[0048] In the present embodiment, asFigures 3 to 5 As shown in FIG. 1, the electromagnetic environment analysis device 3 determines the display range RA in which the measurement result is displayed, by recognizing the range determination marker 2. In a modification of the present embodiment, the electromagnetic environment analysis device 3 can determine the measurement range in which the measurement is performed in the actual space, by recognizing the range determination marker 2.

[0049] As shown in FIG. 1, the electromagnetic environment analysis device 3 has an operation section 10 and a main body section 20. The operation section 10 and the main body section 20 are connected by wire or wirelessly. The operation section 10 includes a sensor 11 and a sensor marker 12. As shown in FIG. 1, the operation section 10 is configured at a desired measurement position by a user. The operation section 10 is moved by the user with respect to the measurement target object 5. The operation section 10 can be moved by the user by hand, or can be moved by the user by electronic operation through a mechanism. The sensor 11 is located in the actual space, and sequentially detects information related to the electromagnetic environment. The sensor 11 sequentially detects a signal set as an object. The sensor 11 includes, for example, an antenna, an electric field probe, or a magnetic field probe. The sensor 11 transmits the detected signal to the main body section 20. The sensor 11 detects, for example, at least one of information related to the intensity of at least one of an electric field or a magnetic field, information related to the intensity of an electromagnetic wave, information related to the phase of an electromagnetic wave, and information related to the waveform of an electromagnetic wave, as detection information. The detection information includes, for example, a current value or a voltage value generated at the electric field probe or the magnetic field probe. The sensor 11 transmits the detected detection information to the main body section 20. Figure 1 Figure 4 Figure 5 As shown in FIG. 1, the operation section 10 is configured at a desired measurement position by a user. The operation section 10 is moved by the user with respect to the measurement target object 5. The operation section 10 can be moved by the user by hand, or can be moved by the user by electronic operation through a mechanism. The sensor 11 is located in the actual space, and sequentially detects information related to the electromagnetic environment. The sensor 11 sequentially detects a signal set as an object. The sensor 11 includes, for example, an antenna, an electric field probe, or a magnetic field probe. The sensor 11 transmits the detected signal to the main body section 20. The sensor 11 detects, for example, at least one of information related to the intensity of at least one of an electric field or a magnetic field, information related to the intensity of an electromagnetic wave, information related to the phase of an electromagnetic wave, and information related to the waveform of an electromagnetic wave, as detection information. The detection information includes, for example, a current value or a voltage value generated at the electric field probe or the magnetic field probe. The sensor 11 transmits the detected detection information to the main body section 20.

[0050] The sensor marker 12 is configured on the sensor 11 in the actual space, and moves together with the sensor 11. In other words, the sensor 11 and the sensor marker 12 also move by the movement of the operation section 10 by the user. The sensor marker 12 is a marker for acquiring the position of the sensor 11 in the actual space. The sensor marker 12, like the range determination marker 2, has characteristic points at which the electromagnetic environment analysis device 3 can recognize the three-dimensional position of the sensor marker 12 in the actual space by image recognition. For example, the sensor marker 12 includes a two-dimensional code or the like pattern having these characteristic points. The two-dimensional code includes, for example, three-dimensional position information of the sensor marker 12. If the electromagnetic environment analysis device 3 can recognize the position of the sensor marker 12 in the actual space, the sensor marker 12 is not limited to this form. The sensor marker 12 does not have information capable of specifying the three-dimensional position as a single body, but has information capable of specifying the position within the captured image.

[0051] As shown in FIG. 1, the operation section 10 is configured at a desired measurement position by a user. The operation section 10 is moved by the user with respect to the measurement target object 5. The operation section 10 can be moved by the user by hand, or can be moved by the user by electronic operation through a mechanism. The sensor 11 is located in the actual space, and sequentially detects information related to the electromagnetic environment. The sensor 11 sequentially detects a signal set as an object. The sensor 11 includes, for example, an antenna, an electric field probe, or a magnetic field probe. The sensor 11 transmits the detected signal to the main body section 20. The sensor 11 detects, for example, at least one of information related to the intensity of at least one of an electric field or a magnetic field, information related to the intensity of an electromagnetic wave, information related to the phase of an electromagnetic wave, and information related to the waveform of an electromagnetic wave, as detection information. The detection information includes, for example, a current value or a voltage value generated at the electric field probe or the magnetic field probe. The sensor 11 transmits the detected detection information to the main body section 20. Figure 1 ​​As shown in FIG. 1, the main body 20 includes a photographing section 21, a storage section 22, a measurement processing section 23, a display section 24, and a display control section 25. The photographing section 21, the storage section 22, the measurement processing section 23, the display section 24, and the display control section 25 can be housed in one frame or can be divided into a plurality of frames. In the case of being housed in a plurality of frames, the photographing section 21, the storage section 22, the measurement processing section 23, the display section 24, and the display control section 25 can be connected to each other by wire or can be connected to each other wirelessly.

[0052] The photographing section 21 sequentially photographs a photographing image in an actual space. The photographing section 21 photographs at a predetermined time interval. The photographing section 21 transmits the photographing image to the display control section 25. In the present embodiment, the photographing section 21 is provided in a frame held by a user. The photographing section 21 is moved by the user. The photographing section 21 changes the position and the posture by the operation of the user.

[0053] The storage section 22 stores data acquired in advance and data that can be acquired from various functional sections in the main body 20. The storage section 22 stores, for example, data acquired from the photographing section 21, the measurement processing section 23, and the display control section 25.

[0054] The measurement processing section 23 acquires detection information detected in the sensor 11, processes the acquired detection information, and outputs the processed detection information as measurement information. The measurement information corresponds to a measurement result. The measurement processing section 23 functions as, for example, a spectrum analyzer, a network analyzer, or an oscilloscope. The measurement processing section 23 transmits the measurement information to the display control section 25. The measurement information includes a plurality of measurement values related to the electromagnetic environment and additional information corresponding to each measurement value. The measurement values include various physical values. In the present embodiment, the measurement values are values indicating the intensity of electromagnetic waves and correspond to the measurement result. For example, the measurement values in the present embodiment are values indicating the intensity of electric fields or magnetic fields. The additional information includes, for example, at least one of information related to the intensity of electromagnetic waves, information related to the phase of electromagnetic waves, information related to the frequency component of electromagnetic waves, and information related to the time at which measurement is performed.

[0055] The measurement processing section 23 acquires a plurality of measurement values related to the electromagnetic environment on the basis of the detection result of the sensor 11. The measurement processing section 23, for example, processes the detection information detected in the sensor 11 and calculates the intensity of a plurality of frequency components as measurement information in each measurement. The measurement processing section 23, for example, sets the intensity of each frequency component as a measurement value in each measurement position. For example, the measurement processing section 23 calculates the intensity of 100 to 500 frequency components in a predetermined frequency band.

[0056] The display section 24 displays at least one of the captured image in the capturing section 21 and the measurement image created in the display control section 25. The measurement image is an image representing the measurement information processed in the measurement processing section 23. The display section 24 includes a display that displays an image. In the present embodiment, the display section 24 is provided in the same housing as the capturing section 21. The display section 24 is moved by the user together with the capturing section 21. As a modification of the present embodiment, the display section 24 can also display an image in a display outside the electromagnetic environment analysis system 1.

[0057] The display control section 25 controls the display of the display section 24. The display control section 25 creates an image displayed in the display section 24 based on at least one of the captured image of the capturing section 21 and the measurement information of the measurement processing section 23. As shown in FIG. 2, the display control section 25 includes a position information acquisition section 31, a display range determination section 32, a position relationship judgment section 33, a measurement information acquisition section 34, and an image creation section 35. Figure 1

[0058] The position information acquisition section 31 acquires position information related to the measurement position at which each measurement value is measured. The position information acquisition section 31 calculates the position information related to the measurement position based on, for example, the captured image in the capturing section 21. As shown in FIG. 3, the position information acquisition section 31 includes a captured image acquisition section 41, a marker detection section 42, and a marker position calculation section 43. Figure 1

[0059] The marker detection section 42 detects at least one of the range determination marker 2 and the sensor marker 12 based on the captured image acquired in the captured image acquisition section 41. In the present embodiment, at least one of the range determination marker 2 and the sensor marker 12 is detected from one captured image. The marker detection section 42 detects the feature points of each range determination marker 2. The marker detection section 42 detects the feature points of the sensor marker 12.

[0060] The marker position calculation section 43 calculates the position of at least one of the range determination marker 2 and the sensor marker 12 based on the detection result of the marker detection section 42. The marker position calculation section 43 calculates the relative position of the range determination marker 2 and the sensor marker 12 based on the detection result of the range determination marker 2 and the detection result of the sensor marker 12. In the present embodiment, the marker position calculation section 43 calculates the position of at least one of the range determination marker 2 and the sensor marker 12 within the captured image. As a modification of the present embodiment, the marker position calculation section 43 can also calculate the three-dimensional position of at least one of the range determination marker 2 and the sensor marker 12 in the actual space.

[0061] ​​In this embodiment, the marker position calculation unit 43 determines the feature points of the marker 2 based on the ranges detected by the marker detection unit 42, and calculates the three-dimensional position of the marker 2 for each range. For example, as Figures 3 to 5 As shown, the marker position calculation unit 43 determines the feature points of marker 2 according to each range, and uses the position P1 of the corner of the QR code of marker 2 in each range of the actual space as the vertex of the display range for calculation. In this embodiment, the marker position calculation unit 43 has the feature points of sensor marker 12 detected by marker detection unit 42, and calculates the three-dimensional position of sensor marker 12. For example, as Figure 4 and Figure 5 As shown, the mark position calculation unit 43 calculates the angular position P2 of the QR code of the sensor mark 12 in the actual space based on the feature points of the sensor mark 12. The position P2 of the sensor mark 12 corresponds to the position of the sensor 11. The position of the sensor 11 at the measurement time corresponds to the measurement position. Hereinafter, the position of the sensor 11 will be referred to as the "sensor position".

[0062] The display range determination unit 32 determines the display range RA in the image that displays information related to the measurement value based on the detection result of the marker detection unit 42. The display range determination unit 32 determines the position of marker 2 based on the range calculated in the marker position calculation unit 43, and determines the display range RA in the display unit 24 that displays the measurement information. In this embodiment, the display range determination unit 32 determines the position of marker 2 based on two ranges calculated in the marker position calculation unit 43, and uses this as the display range RA. For example, the marker position calculation unit 43 calculates the range to determine the position P1 of markers 2a and 2b, or determines the size of the area defined by markers 2a and 2b based on the range, based on the detection result of the marker detection unit 42. For example, as... Figures 3 to 5 As shown, the display range determination unit 32 determines the display range RA as the rectangular area whose two vertices are on the diagonal of the position P1 of each range determination mark 2. In other words, the display range determination unit 32 determines, for example, the quadrilateral area whose diagonal is the line connecting the position P1 of range determination mark 2a and the position P1 of range determination mark 2b.

[0063] The marker position calculation unit 43 can also calculate a range to determine the size of the marker 2 based on the detection result of the marker detection unit 42. For example, the marker position calculation unit 43 can also obtain information related to the relative position of the imaging unit 21 and the range determination marker 2 from the size of the range determination marker 2. In this case, the display range determination unit can also determine the display range RA corresponding to the size of the information related to the relative position of the imaging unit 21 and the range determination marker 2. For example, the display range determination unit 32 can also determine the radius of the circle based on the size of the marker 2 determined by the range calculated by the marker position calculation unit 43.

[0064] The position relationship determination section 33 determines the position relationship between the display range RA determined by the display range determination section 32 and the sensor position calculated by the marker position calculation section 43. For example, the position relationship determination section 33 determines whether the sensor position is located within the display range RA. For example, the position relationship determination section 33 determines whether the position P2 of the sensor marker 12 is located within the display range RA.

[0065] The measurement information acquisition section 34 acquires measurement information from the measurement processing section 23. In other words, the measurement information acquisition section 34 acquires a plurality of measurement values related to the electromagnetic environment and additional information corresponding to each measurement value. The measurement information acquisition section 34 acquires the plurality of measurement values output from the measurement processing section 23 based on the detection information detected by the sensor 11. The measurement information acquisition section 34 passes the acquired measurement information to the image production section 35. The measurement information acquisition section 34, for example, associates the measurement positions with the measurement values and stores them in the storage section 22. The measurement information acquisition section 34 can also acquire the measurement values and the measurement positions associated with each other from the storage section 22.

[0066] The image production section 35 produces an image that displays information related to the measurement values at positions corresponding to the measurement positions of the measurement values. The image produced in the image production section 35 is displayed in the display section 24, for example. The image production section 35 produces the image based on the detection result of the marker detection section 42. The image production section 35 produces a result image that corresponds the measurement positions calculated in the marker position calculation section 43 to the measurement results. In the present embodiment, the result image contains at least one of information indicating the sensor position, information indicating the display range RA, and information indicating the measurement results. For example, as shown in Figure 4 and Figure 5 indicated by the measurement position. The image production section 35 produces a result image that indicates only the display range RA in a case where the measurement value corresponding to the display range RA is not acquired. In the present embodiment, the image production section 35 produces a composite image in which the result image coincides with the captured image. As shown in Figure 1 The image production section 35 contains a division processing section 51, a display information determination section 52, and a compositing section 53, as shown in

[0067] The division processing section 51 performs processing of setting a plurality of divisions PA within the display range RA, as shown in Figure 5 The plurality of divisions PA are regions that divide the display range RA. In other words, the display range RA is formed by the plurality of divisions PA. In other words, the plurality of divisions PA are regions that divide the display range RA in which the measurement results are displayed in the result image produced in the image production section 35. Each division PA is larger than the resolution of the measurement position. Figure 5In the present embodiment, the case where a plurality of measurement positions P4 are located within one zone PA is indicated. As shown in Fig. 6, the zone processing section 51 includes a zone setting section 61, a zone determination section 62, and a re-setting determination section 63. Figure 1 As shown in Fig. 6, the zone setting section 61 sets a plurality of zones PA in the display range RA. In other words, the zone setting section 61 sets a plurality of zones PA by dividing the display range RA in which information related to the measurement value is displayed. In other words, the display range RA is formed by a plurality of zones PA. In the present embodiment, the zone setting section 61 refers to a zone definition table stored in advance in the storage section 22, and sets a plurality of zones PA based on information shown in the zone definition table.

[0068] (b) of Fig. 7 indicates an example of the zone definition table. The storage section 22 stores, for example, a plurality of zone definition tables 71, 72 in advance. Each of the zone definition tables 71, 72 defines the structure of a plurality of zones forming the display range RA. The plurality of zone definition tables 71, 72 define the structure of each zone PA in the divided display range RA according to mutually different numbers. In other words, the structure of each zone PA in the case where the display range RA is divided according to mutually different numbers is defined. Figure 6 Figure 6 (b) of Fig. 7 indicates an example of the zone definition table. The storage section 22 stores, for example, a plurality of zone definition tables 71, 72 in advance. Each of the zone definition tables 71, 72 defines the structure of a plurality of zones forming the display range RA. The plurality of zone definition tables 71, 72 define the structure of each zone PA in the divided display range RA according to mutually different numbers. In other words, the structure of each zone PA in the case where the display range RA is divided according to mutually different numbers is defined.

[0069] For example, the zone setting section 61 sets the zone definition table used for determination in the zone determination section 62 according to the plurality of zone definition tables 71, 72 stored in advance in the storage section 22. Figure 6 The zone definition table 71 shown in (a) of Fig. 7 and the zone definition table 72 shown in (b) of Fig. 7 indicate the size and number of a plurality of zones PA forming the display range RA, and the position at which each zone PA is set. The zone definition table can also indicate the number of times the display range RA is divided. Figure 6 The zone definition table 71 shown in (a) of Fig. 7 and the zone definition table 72 shown in (b) of Fig. 7 indicate the size and number of a plurality of zones PA forming the display range RA, and the position at which each zone PA is set. The zone definition table can also indicate the number of times the display range RA is divided. Figure 7 (a) of Fig. 7 indicates the state in which the display range RA is divided based on the zone definition table 71. Figure 7 (b) of Fig. 7 indicates the state in which the display range RA is divided based on the zone definition table 72. By changing the zone definition table, the zone PA is changed from the zone PA1 to the zone PA2. The zone definition table 71 and the zone definition table 72 differ in the number of times the display range RA is divided. The zone PA1 and the zone PA2 differ in size from each other. The size of each zone PA indicated in the zone definition table 72 is smaller than the size of each zone PA indicated in the zone definition table 71.

[0070] ​The division determination section 62 determines the division PA corresponding to the measurement position of each measurement value based on the position information acquired by the position information acquisition section 31. In the present embodiment, the division determination section 62 calculates the coordinates of the measurement position P4 within the display range RA, i.e., the coordinates of the position P2 of the sensor marker 12, based on the relative position of the range determination marker 2 to the sensor marker 12 calculated by the marker position calculation section 43. For example, the division determination section 62 calculates the coordinates of the position P2 of the sensor marker 12 with the position PI of the range determination marker 2a as the origin. The division determination section 62 determines the division PA corresponding to the measurement value based on the calculated coordinates. In the present embodiment, the division determination section 62 determines the division PA corresponding to the measurement position of each measurement value based on the division definition table set in the division setting section 61. The division determination section 62 stores the determination result in the storage section 22, for example.

[0071] Figure 8 An example of the measurement information stored in the storage section 22 after the division is determined by the division determination section 62 is shown in FIG. 17. Figure 8 In FIG. 17, the storage section 22 stores the measurement information D1 to D4 in which the X and Y coordinates representing the measurement position are associated with the measurement value. Figure 8 The column of the division in FIG. 17 represents the determination result of the division determination section 62. Figure 8 In the example shown in FIG. 17, the division PA corresponding to the measurement position of each measurement value is determined based on the X and Y coordinates representing the measurement position and the division definition table 71.

[0072] The reset determination section 63 determines whether the plurality of divisions PA is reset by the division setting section 61. In other words, the reset determination section 63 determines whether the size of the plurality of divisions PA forming the display range RA is changed. In a case where the reset determination section 63 determines that the plurality of divisions PA is reset, the division setting section 61 performs the reset of the plurality of divisions PA by changing the number of the plurality of divisions PA forming the display range RA. For example, the division setting section 61 performs the reset of the plurality of divisions PA by changing the number of the display ranges RA. For example, in a case where the reset determination section 63 determines that the plurality of divisions PA is reset, the division setting section 61 changes the division definition table. In this case, the division setting section 61 changes the division definition table to be referred to from the division definition table 71 shown in (a) of FIG. 16 to the division definition table 72 shown in (b) of FIG. 16, for example. Figure 6 Figure 6 In a case where the reset determination section 63 determines that the plurality of divisions PA is reset, the division setting section 61 resets the plurality of divisions PA forming the display range RA from the plurality of divisions PA1 shown in (a) of FIG. 16 to the plurality of divisions PA2 shown in (b) of FIG. 16, for example, by the change of the division definition table. Figure 7 Figure 7

[0073] ​​​When the multiple zones PA are re-set by the zone setting section 61, the zone determination section 62 determines the zones PA corresponding to the measurement positions of the respective measurement values among the re-set multiple zones PA. In other words, the zone determination section 62 re-determines the zones PA corresponding to the measurement positions of the respective measurement values based on the changed zone definition table. For example, in a case where the re-set determination section 63 determines to re-set the multiple zones PA and the zone setting section 61 re-sets the multiple zones PA2, the zone determination section 62 determines the zones PA2 corresponding to the measurement positions of the respective measurement values among the multiple zones PA2 based on the position information.

[0074] In the present embodiment, the re-set determination section 63 determines to re-set in a case where a predetermined condition is satisfied in the process within the electromagnetic environment analysis device 3. For example, the re-set determination section 63 determines to re-set in a case where the number of the zones PA corresponding to the measurement values exceeds a predetermined number. In other words, the re-set determination section 63 determines to re-set in a case where the number of the zones PA in which the measurement results are displayed exceeds a predetermined value. The re-set determination section 63 determines to re-set in a case where, for example, the proportion of the number of the zones PA corresponding to the measurement values to the number of divisions of the display range RA exceeds a predetermined value. The "number of divisions of the display range RA" is the number in which the display range RA is divided, that is, the number of the zones PA forming the display range RA. The re-set determination section 63 prohibits re-setting the multiple zones PA in a case where the number of times of re-setting the multiple zones PA exceeds a predetermined number.

[0075] The re-set determination section 63 can determine to re-set the multiple zones PA in a case where at least one of the multiple conditions set in advance is satisfied. The size of each zone re-set by the zone setting section 61 can be different depending on the satisfied condition. In other words, the number in which the display range RA is divided can be different depending on the satisfied condition.

[0076] The multiple conditions can be operations or calculations by mutually different users, or can be different times or numbers of input of the same operation or calculation. For example, the zone setting section 61 can re-set the multiple zones PA in a case where a condition such as a first input operation by a user is satisfied, and can re-set the multiple zones PA again in a case where a condition such as a second input operation by the user is satisfied. In this case, the size of each zone re-set by the zone setting section 61 in a case where the condition such as the first input operation is satisfied can be smaller than the size of each zone re-set by the zone setting section 61 in a case where the condition such as the second input operation is satisfied. In other words, the size of each zone re-set by the zone setting section 61 in a case where a first condition is satisfied can be smaller than the size of each zone re-set by the zone setting section 61 in a case where a second condition is satisfied before the first condition is satisfied.

[0077] As a modification of the present embodiment, the re-setting determination section 63 can also determine that re-setting is performed in accordance with a prescribed input operation performed by the user. For example, in a case where a switch is operated by the user, the re-setting determination section 63 can also determine that re-setting is performed. For example, the re-setting determination section 63 determines that a prescribed condition is satisfied in processing in the electromagnetic environment analysis device 3 and that a prescribed input operation is performed by the user in accordance with a state of a flag.

[0078] The display information determination section 52 determines information displayed in the display section 24. For example, information determined by the display information determination section 52 is displayed as an image in the display section 24. The display information determination section 52 determines, for example, information used in production of a result image. The display information determination section 52 determines information related to display of each division PA on the basis of a measured value corresponding to each division PA. The display information determination section 52 determines information displayed in a division PA corresponding to a measured value. In the present embodiment, the display information determination section 52 determines information displayed in a division PA having no corresponding measured value as Null. As a modification of the present embodiment, the display information determination section 52 can not determine information in a division PA having no corresponding measured value.

[0079] In a case where the re-setting determination section 63 determines that a plurality of divisions PA are re-set, the display information determination section 52 determines information related to display of a division PA on the basis of a measured value corresponding to the re-set division PA. For example, in a case where the re-setting determination section 63 determines that a plurality of divisions PA are re-set and the division setting section 61 re-sets a plurality of divisions PA2, the display information determination section 52 determines information related to display of the division PA2 on the basis of a measured value corresponding to the division PA2.

[0080] The display information determination section 52 determines a representative value from, for example, a measured value corresponding to each division PA, and determines information related to display of each division PA on the basis of the representative value. The information related to display of each division PA is, for example, a color displayed in each division PA. The information related to display of each division PA can not be a color, but a number or a symbol indicating the representative value. In the present embodiment, the display information determination section 52 determines a representative value in a division PA having no corresponding measured value as Null. The display information determination section 52 determines, in a case where the representative value corresponding to a division PA is Null, information such that the division PA is set to be colorless or not displayed.

[0081] The display information determination section 52 determines a color displayed in each division PA from, for example, a magnitude of a measured value corresponding to each division PA. For example, the display information determination section 52 determines a color displayed in each division PA to be Figure 9The colors in the color distribution table 55 shown correspond to the magnitudes of the measured values. Figure 9 In the diagram, arrow V represents a measured value within a certain zoning area PA. Figure 9 In this context, the higher the measured value, the higher the concentration of the color displayed in each PA zone. For example, ... Figure 5 As shown, multiple color zones PA are divided according to the magnitude of the measured values ​​located in each zone PA. The display information determination unit 52 can also display icons in the zones PA containing predetermined representative values ​​within the display range RA. The predetermined representative value is, for example, the largest representative value within the display range RA. The predetermined representative value could also be, for example, the smallest representative value within the display range RA, etc.

[0082] like Figure 5 As shown, when two or more measured values ​​measured at different times correspond to a zone PA, the display information determination unit 52 calculates a representative value using the two or more measured values ​​and determines information related to the display of the zone PA based on the representative value. "Two or more measured values ​​correspond to a zone PA" means that a measurement position P4 with two or more measured values ​​is configured within a zone. The display information determination unit 52 calculates a representative value using the two or more measured values ​​based on additional information. "Calculation of representative values ​​from two or more measured values" includes selecting "representative values ​​from two or more measured values". In this embodiment, the display information determination unit 52 selects a representative value using two or more measured values ​​based on information related to the intensity of electromagnetic waves. For example, the display information determination unit 52 sets the maximum, minimum, median, or mode of two or more measured values ​​as the representative value and determines information related to the display of the zone PA. As a variation of this embodiment, the display information determination unit 52 may also calculate the average of two or more measured values, set the calculated average as the representative value, and determine information related to the display of the zone PA.

[0083] As a modification of the present embodiment, the display information determination section 52 can determine information related to the display of each zone PA based on the frequency component. For example, a case where the plurality of measurement values include a plurality of first measurement values related to electromagnetic waves of a first frequency component and a plurality of second measurement values related to electromagnetic waves of a second frequency component is studied. In this case, the display information determination section 52 determines first information related to the display of the zone PA based on, for example, the first measurement values corresponding to the zone PA. The display information determination section 52 determines second information related to the display of the zone PA based on, for example, the second measurement values corresponding to the zone PA. The display information determination section 52 calculates a first representative value using two or more first measurement values when two or more first measurement values measured at mutually different times correspond to one zone PA, and determines the first information related to the display of the zone PA based on the first representative value. The display information determination section 52 calculates a second representative value using two or more second measurement values when two or more second measurement values measured at mutually different times correspond to one zone PA, and determines the second information related to the display of the zone PA based on the second representative value. The first information and the second information can be displayed simultaneously in each zone PA.

[0084] As a modification of the present embodiment, the display information determination section 52 can select at least one measurement value from two or more measurement values based on the frequency component, and calculate a representative value using the selected at least one measurement value. For example, the display information determination section 52 calculates one measurement value as a representative value using two or more measurement values selected based on the frequency component based on other additional information other than the frequency component. For example, the display information determination section 52 can determine information related to the display of the zone PA based on information related to the intensity of electromagnetic waves by setting an average value of two or more measurement values selected based on the frequency component as a representative value. For example, the display information determination section 52 can select a measurement value related to electromagnetic waves of a prescribed frequency band from two or more measurement values. The display information determination section 52 can select a measurement value related to electromagnetic waves of a plurality of frequency components from two or more measurement values.

[0085] The synthesis section 53 creates a synthesized image that synthesizes the result image and the captured image. The image creation section 35 outputs the synthesized image created in the synthesis section 53 to the display section 24. The synthesis section 53 does not create a synthesized image in the absence of at least one of the result image and the captured image. The image creation section 35 outputs only the result image to the display section 24 in the absence of the captured image. The image creation section 35 outputs only the captured image to the display section 24 in the absence of the result image.

[0086] Next, the reference Figure 10 The hardware structure of the electromagnetic environment analysis device 3 will be described. Figure 10is a diagram showing an example of a hardware configuration of the electromagnetic environment analysis device 3.

[0087] The electromagnetic environment analysis device 3 is provided with a processor 101, a main storage device 102, an auxiliary storage device 103, a communication device 104, an input device 105, an output device 106, an imaging device 107, a probe 108, and a display 109. The electromagnetic environment analysis device 3 includes one or a plurality of computers configured by these hardware and software such as programs. The electromagnetic environment analysis device 3 is realized by cooperation with the hardware.

[0088] In a case where the electromagnetic environment analysis device 3 is configured by a plurality of computers, these computers can be connected by a local connection, or can be connected via a communication network such as the Internet or an intranet. By this connection, one electromagnetic environment analysis device 3 is logically configured.

[0089] The processor 101 executes an operating system and application programs and the like. The main storage device 102 is configured by a ROM (Read Only Memory) and a RAM (Random Access Memory). For example, at least a part of the measurement processing section 23 and the display control section 25 is realized by the processor 101 and the main storage device 102. The processor 101 and the main storage device 102 configure a part of a spectrum analyzer, a network analyzer, or an oscilloscope.

[0090] The auxiliary storage device 103 is a storage medium configured by a hard disk and a flash memory and the like. The auxiliary storage device 103 generally stores a larger amount of data than the main storage device 102. For example, at least a part of the storage section 22 is realized by the auxiliary storage device 103.

[0091] The auxiliary storage device 103 stores programs and data necessary in processing in advance. The programs cause the computer to execute each functional element of the electromagnetic environment analysis device 3. By the programs, for example, the processing S1 and the processing S3 to the processing S7 described later are executed in the computer. The programs can also be provided by being recorded in a tangible recording medium such as a CD-ROM, a DVD-ROM, a semiconductor memory, and the like. The programs can also be provided as a data signal via a communication network.

[0092] The communication device 104 is configured by a network card or a wireless communication module. For example, at least a part of the photographed image acquisition section 41 and the measurement information acquisition section 34 is realized by the communication device 104. The input device 105 is configured by a keyboard, a mouse, a touch panel, and the like. For example, at least a part of the operation section 10, the display section 24, the photographed image acquisition section 41, the measurement information acquisition section 34, and the re-setting determination section 63 is realized by the input device 105. The output device 106 is configured by an alarm and a printer and the like. For example, at least a part of the image production section 35 is realized by the output device 106.

[0093] The imaging device 107 is constituted by a video camera or a still camera. For example, at least a part of the imaging section 21 is realized by the imaging device 107. The probe 108 is connected to an input terminal of a spectrum analyzer, a network analyzer, or an oscilloscope. For example, at least a part of the operation section 10 is realized by the probe 108. The display 109 includes a monitor of a computer, a display screen of a mobile terminal, or a projection screen. For example, at least a part of the display section 24 is realized by the display 109.

[0094] Next, referring to Figures 11 to 14 An example of a measurement method using the electromagnetic environment analysis system will be described. Figure 11 is a flowchart showing an electromagnetic environment analysis method using the electromagnetic environment analysis system.

[0095] First, the division processing section 51 acquires initial settings of a plurality of divisions PA (process S1). For example, the division processing section 51 acquires initial settings which are previously stored in the storage section 22. The initial settings include, for example, a division definition table.

[0096] Next, the range determination markers 2 are arranged (process S2). For example, the user arranges a plurality of range determination markers 2 around a display range of a measurement result. In other words, the user arranges a plurality of range determination markers 2 around a range in which measurement is performed. The plurality of range determination markers 2 can also be arranged at a position which is previously set by a not-shown device included in the electromagnetic environment analysis system 1. In the present embodiment, as shown in Figure 3 each of the two range determination markers 2 is arranged at a vertex on a diagonal line of the desired display range RA.

[0097] Next, the photographed image acquisition section 41 acquires a photographed image (process S3). The photographed image acquisition section 41 acquires a photographed image which is photographed in the imaging section 21. The imaging section 21 photographs the range determination markers 2. For example, the imaging section 21 performs imaging so that all of the plurality of range determination markers 2 arranged in the process S2 enter one photographed image. For example, the imaging section 21 performs imaging so as to acquire a feature point indicating a three-dimensional position for each range determination marker 2. In the process S3, the imaging section 21 can also photograph the sensor marker 12 together with the range determination markers 2.

[0098] Next, a marker detection process is performed by the marker detection section 42, the marker position calculation section 43, the display range determination section 32, and the position relationship determination section 33 (process S4). In the marker detection process, the positions of the range determination markers 2 and the sensor marker 12 are acquired from the photographed image acquired in the process S3. In the marker detection process, the positional relationship of the range determination markers 2 and the sensor marker 12 is determined.

[0099] Next, the display control section 25 determines whether to acquire the captured image again (process S5). The display control section 25 determines whether to acquire the captured image again based on the detection results of the range determination marker 2 and the sensor marker 12 in the process S4. In a case where it is determined to acquire the captured image again, the process returns to the process S3.

[0100] In the process S5, in a case where it is determined not to acquire the captured image again, the display processing of the measurement result is performed by the image production section 35 (process S6). In the display processing of the measurement result, a result image corresponding to the position where the measurement was performed and the measurement result is displayed in the display section 24.

[0101] Next, the display control section 25 determines whether to end the process (process S7). In the process S7, in a case where it is determined not to end the process, the process returns to the process S3. In the process S7, in a case where it is determined to end the process, the series of processes is ended.

[0102] Next, the marker detection processing in the process S4 will be described in detail. Figure 12 is a flowchart showing the marker detection processing.

[0103] First, the marker detection section 42 determines whether the range determination marker 2 is present in the captured image (process S11). The marker detection section 42 performs image detection of the feature points of the range determination marker 2 using, for example, the captured image. The marker detection section 42 determines that the range determination marker 2 is present in the captured image in a case where the feature points of the range determination marker 2 are recognized in the captured image. The marker detection section 42 determines that the range determination marker 2 is not present in the captured image in a case where the feature points of the range determination marker 2 are not recognized in the captured image. In the process S11, in a case where it is determined that the range determination marker 2 is present, the process proceeds to the process S12. In the process S11, in a case where it is determined that the range determination marker 2 is not present, the process proceeds to the process S21.

[0104] In a case where it is determined in the process S11 that the range determination marker 2 is present, it is determined whether the sensor marker 12 is present in the captured image (process S12). The marker detection section 42 performs image detection of the feature points of the sensor marker 12 using, for example, the captured image. The marker detection section 42 determines that the sensor marker 12 is present in the captured image in a case where the feature points of the sensor marker 12 are recognized in the captured image. The marker detection section 42 determines that the sensor marker 12 is not present in the captured image in a case where the feature points of the sensor marker 12 are not recognized in the captured image. In the process S12, in a case where it is determined that the sensor marker 12 is present, the process proceeds to the process S17. In the process S12, in a case where it is determined that the sensor marker 12 is not present, the process proceeds to the process S13.

[0105] When it is determined in the processing S12 that there is no sensor mark 12, the mark position calculating section 43 acquires the position PI of the range determination mark 2 (processing S13). For example, the mark position calculating section 43 calculates the position PI of the range determination mark 2 within the captured image, and outputs the calculation result to the position relationship judging section 33 and the storage section 22.

[0106] When the processing S13 ends, the position relationship judging section 33 judges whether the position PI of the range determination mark 2 is appropriate (processing S14). For example, the position relationship judging section 33 judges whether the position relationship of the plurality of range determination marks 2a, 2b is appropriate. For example, the position relationship judging section 33 judges that the position relationship of the plurality of range determination marks 2a, 2b is appropriate when each of the range determination marks 2a, 2b is disposed at a position where the display range RA of the rectangle can be specified. For example, the position relationship judging section 33 judges that each of the range determination marks 2a, 2b is disposed at a position where the display range RA can be specified when the position PI of the range determination mark 2a is located at the upper left of the position PI of the range determination mark 2b in the captured image. When it is judged that the position PI of the range determination mark 2 is not appropriate, the processing proceeds to the processing S15. When it is judged that the position PI of the range determination mark 2 is appropriate, the processing proceeds to the processing S16.

[0107] When it is judged in the processing S14 that the position PI of the range determination mark 2 is not appropriate, the display control section 25 causes the display section 24 to display the captured image (processing S15). For example, in the processing S15, the display information determining section 52 determines that only the captured image is displayed on the display section 24. The image producing section 35 does not produce a composite image in the compositing section 53, and outputs only the captured image to the display section 24. As a result, the display section 24 displays only the captured image. When the processing S15 ends, the mark detection processing ends, and the processing result is returned.

[0108] When it is judged in the processing S14 that the position PI of the range determination mark 2 is appropriate, the display control section 25 causes the display section 24 to display the captured image and the display range RA (processing S16). In the processing S16, the display range determining section 32 determines the display range RA based on the detection result of the range determination mark 2. For example, in the processing S16, the display information determining section 52 determines that the display range RA and the captured image are displayed in the display section 24. The image producing section 35 outputs a composite image in which a result image indicating only the display range RA and the captured image are synthesized, to the display section 24. As a result, as shown in FIG. 6, the display section 24 displays the display range RA and the captured image. When the processing S16 ends, the mark detection processing ends, and the processing result is returned. Figure 3

[0109] ​When it is determined in the processing S12 that the sensor marker 12 is present, the marker position calculating section 43 acquires the position PI of the range determination marker 2 and the position P2 of the sensor marker 12 (processing S17). For example, the marker position calculating section 43 calculates the position PI of the range determination marker 2 within the captured image and the position P2 of the sensor marker 12 within the captured image, and outputs the calculation results to the position relationship judging section 33 and the storage section 22. In the processing S17, the marker position calculating section 43 calculates the relative positions of the range determination marker 2 and the sensor marker 12 based on the detection results of the range determination marker 2 and the detection results of the sensor marker 12. The position P2 of the sensor marker 12 is position information related to the measurement position at which the measurement value is measured. In the present embodiment, the position P2 of the sensor marker 12 coincides with the measurement position.

[0110] When the processing S17 ends, the position relationship judging section 33 judges whether the positions of the range determination marker 2 and the sensor marker 12 are appropriate (processing S18). For example, the position relationship judging section 33 judges whether the positional relationship of the plurality of range determination markers 2a, 2b is appropriate. For example, as in the processing S14, in a case where each of the range determination markers 2a, 2b is arranged at a position at which the display range RA of the rectangle can be specified, the position relationship judging section 33 judges that the positional relationship of the plurality of range determination markers 2a, 2b is appropriate. In a case where it is judged that the position PI of the range determination marker 2 is inappropriate, the processing proceeds to the processing S13. In a case where it is judged that the position PI of the range determination marker 2 is appropriate, the processing proceeds to the processing S19.

[0111] In a case where it is judged in the processing S18 that the position PI of the range determination marker 2 is appropriate, it is judged whether the measurement position is within the display range RA (processing S19). For example, the position relationship judging section 33 judges that the measurement position is within the display range RA in a case where the position P2 of the sensor marker 12 is within the display range RA. In a case where it is judged that the measurement position is not within the display range RA, the processing proceeds to the processing S20. In a case where it is judged that the measurement position is within the display range RA, the marker detection processing ends, and the processing returns to the processing result.

[0112] If, in process S19, it is determined that the measurement position is not within the display range RA, the display control unit 25 causes the display unit 24 to display the captured image, the display range RA, and the sensor position (process S20). In process S20, the display range determination unit 32 determines the display range RA based on the detection result of the range determination mark 2. For example, in process S20, the display information determination unit 52 determines to display the display range RA, the captured image, and the sensor position on the display unit 24. For example, in process S20, the display information determination unit 52 calculates the display range RA using the position P1 of the range determination mark 2 obtained in process S17, and calculates the sensor position using the position P2 of the sensor mark 12 obtained in process S17. The image processing unit 35 outputs a composite image, which combines the result image representing the display range RA and the sensor position with the captured image, to the display unit 24. As a result, such as Figure 4 As shown, display unit 24 displays the display range RA, sensor position, and captured image. When processing S20 ends, the marker detection processing ends, and the processing result is returned.

[0113] If it is determined in process S11 that there is no range determination marker 2, then it is determined whether sensor marker 12 is present in the captured image (process S21). For example, similar to process S12, the marker detection unit 42 performs image detection of feature points of sensor marker 12 based on the captured image. If it is determined in process S21 that sensor marker 12 is present, the process proceeds to process S22. If it is determined in process S21 that sensor marker 12 is not present, the process proceeds to process S24.

[0114] If sensor marker 12 is detected in process S21, the marker position calculation unit 43 obtains the position P2 of sensor marker 12 (process S22). For example, the marker position calculation unit 43 calculates the position P2 of sensor marker 12 within the captured image and outputs the calculation result to the display information determination unit 52 and the storage unit 22. In this embodiment, the position P2 of sensor marker 12 coincides with the measurement position.

[0115] When process S22 ends, the display control unit 25 causes the display unit 24 to display the captured image and sensor position (process S23). For example, in process S23, the display information determination unit 52 determines to display the captured image and sensor position on the display unit 24. For example, in process S23, the display information determination unit 52 calculates the sensor position based on the position P2 of the sensor marker 12 obtained in process S22. The image processing unit 35 outputs a composite image, which combines the result image showing only the sensor position and the captured image, to the display unit 24. When process S23 ends, the marker detection process ends, and the processing result is returned.

[0116] In a case where it is determined in the processing S21 that there is no sensor mark 12, the display control section 25 causes the display section 24 to display the captured image (processing S24). For example, in the processing S24, the display information determination section 52 determines to display only the captured image in the display section 24. The image production section 35 does not produce a composite image in the composition section 53, and outputs only the captured image to the display section 24. As a result, the display section 24 displays only the captured image. When the processing S24 ends, the mark detection processing ends, and the processing returns the processing result.

[0117] Next, the display processing of the measurement result in the processing S6 will be described in detail. Figure 13 is a flowchart showing the display processing of the measurement result.

[0118] First, it is determined whether the measurement information acquisition section 34 acquires the measurement value (processing S31). In a case where the measurement information acquisition section 34 acquires the measurement value from the measurement processing section 23, it is determined that the measurement value is acquired. In a case where the measurement information acquisition section 34 does not acquire the measurement value, the processing returns to the processing S31. In a case where the measurement information acquisition section 34 acquires the measurement value, the processing proceeds to a processing S32.

[0119] In a case where it is determined that the measurement value is acquired, the measurement information acquisition section 34 associates the measurement value and the measurement position with each other (processing S32). The measurement information acquisition section 34 acquires the measurement position acquired in the processing S17 from the position information acquisition section 31. The measurement information acquisition section 34 stores the measurement value and the measurement position associated with each other, for example, to the storage section 22. The measurement information acquisition section 34 outputs the measurement value and the measurement position associated with each other to the image production section 35. The measurement information acquisition section 34 can acquire the measurement value and the measurement position associated with each other from the storage section 22.

[0120] Next, the zone determination section 62 determines the zone PA corresponding to the measurement position (processing S33). The zone determination section 62 determines the zone PA in the plurality of zones PA corresponding to the measurement position of each measurement value, based on the position information acquired in the position information acquisition section 31. The plurality of zones PA set in the processing S33 are the zones PA distinguished by the initial setting in the processing S1. The zone setting section 61 can distinguish the display range RA at the timing when the initial setting is acquired in the processing S1, or can distinguish the display range RA before the processing S33 or in the processing S33.

[0121] In the present embodiment, the division determination section 62 determines the division PA corresponding to the measurement position of each measurement value acquired every other time in the measurement processing section 23. As a modification of the present embodiment, the division PA corresponding to the measurement position of each of the plurality of measurement values stored in the storage section 22 at one time can also be determined. The division determination section 62 stores the determination result in the storage section 22, for example. The division determination section 62 can also output the determination result to the display information determination section 52.

[0122] Next, the display information determination section 52 determines the representative value in the division PA (process S34). The display information determination section 52 acquires the measurement value corresponding to the division PA of the object from the division determination section 62 or the storage section 22. The display information determination section 52 determines the representative value based on the measurement value corresponding to the division PA, for example. The display information determination section 52 calculates and determines the representative value using two or more measurement values corresponding to one division PA when two or more measurement values measured at mutually different times correspond to one division PA.

[0123] Next, the division processing section 51 performs the re-setting processing of the division PA (process S35). The division processing section 51 performs the re-setting of the division PA in the division setting section 61 when the re-setting determination section 63 determines that the plurality of divisions PA is to be re-set. The re-setting determination section 63 performs the re-setting of the plurality of divisions PA when a flag indicating that a prescribed condition is satisfied in the processing in the electromagnetic environment analysis device 3 or a prescribed input is made by the user is detected.

[0124] Next, the display information determination section 52 determines the information related to the display of the division PA based on the representative value (process S36). In the present embodiment, the display information determination section 52 determines the color displayed in the division PA based on the representative value. For example, the display information determination section 52 determines the color displayed in each division PA according to the magnitude of the measurement value corresponding to each division PA. For example, the display information determination section 52 determines the color displayed in the division PA to be the color corresponding to the magnitude of the representative value corresponding to the division PA. In process S36, the display information determination section 52 can also determine information other than the color according to the representative value of each division PA. The display information determination section 52 stores the information related to the display of each division PA in the storage section 22.

[0125] Next, the display control section 25 causes the display section 24 to display the captured image, the display range RA, the sensor position, and the measurement result (process S37). In the process S37, the display range determination section 32 determines the display range RA based on the detection result of the range determination mark 2. The display control section 25 acquires information necessary for display, for example, from the storage section 22. For example, the display information determination section 52 determines to display the captured image, the display range RA, the sensor position, and the measurement result in the display section 24. For example, in the process S37, the display information determination section 52 calculates the display range RA using the position PI of the range determination mark 2 acquired in the process S17 and calculates the sensor position using the position P2 of the sensor mark 12 acquired in the process S17. The measurement result is expressed by a color determined in the process S36, for example. The image production section 35 outputs a composite image in which a result image expressing the display range RA, the sensor position, and the measurement result is synthesized with the captured image to the display section 24. The measurement result is expressed by displaying information related to the measurement value at a position corresponding to the measurement position of the measurement value. As a result, the display section 24 displays the display range RA, the sensor position, the measurement result, and the captured image. When the process S37 ends, the mark detection process ends, and the process returns to the process result.

[0126] In Figure 5 , the measurement positions P4 of two or more measurement values are located in one zone PA. In this case, a representative value is also calculated and determined in the process S33 and the process S34, and in the process S36, information related to the display of the zone PA is determined based on the representative value. As a result, a color corresponding to the representative value is displayed in each zone PA. In other words, when two or more measurement values measured at mutually different times correspond to one zone PA, information based on the representative value is also displayed.

[0127] Next, an example of the zone re-setting process in the process S35 will be described in detail. Figure 14 is a flowchart showing an example of the zone re-setting process.

[0128] First, the re-setting determination section 63 determines whether or not the re-setting of the zone PA is performed (process S41). In the present embodiment, the re-setting determination section 63 determines whether or not a condition such as a ratio of the number of zones PA in which the display of the measurement result is performed to the number of divisions of the display range RA exceeds a prescribed value is satisfied. This prescribed value is stored in the storage section 22 together with the zone definition table. In a case where the above ratio does not exceed the prescribed value, the zone re-setting process ends. In a case where the above ratio exceeds the prescribed value, the process proceeds to the process S42.

[0129] In a case where the above ratio exceeds the prescribed value, the zone definition table to which the zone setting section 61 refers is changed (process S42). The zone setting section 61 changes the zone definition table to be referred to, for example, from the zone definition table 1 to the zone definition table 2. Figure 6the zone definition table 71 shown in (a) of FIG. 7 is changed to Figure 6 the zone definition table 72 shown in (b) of FIG. 7. The number of ranges RA distinguished in the zone definition table 72 is larger than the number of ranges RA distinguished in the zone definition table 71. In a case where the zone definition table 71 corresponds to the first zone definition table, the zone definition table 72 corresponds to the second zone definition table.

[0130] Next, the zone setting section 61 performs re-setting of the plurality of zones PA (process S43). In the process S43, the zone setting section 61 re-sets the plurality of zones PA with reference to the zone definition table 72 changed in the process S42. In the processes S42 and S43, the zone setting section 61 re-sets the plurality of zones PA so as to change the number of zones PA forming the display range RA. Thereby, the zone setting section 61 changes the size of each zone PA. The zone setting section 61 changes the plurality of zones PA forming the display range RA from Figure 7 the plurality of zones PA1 shown in (a) of FIG. 7 to Figure 7 the plurality of zones PA2 shown in (b) of FIG. 7. Each of the plurality of zones PA2 has a different size from the zones PA1. In the present embodiment, the size of each zone PA2 is smaller than the size of each zone PA1. As a result, the zones PA classifying the measurement positions P4 of the measurement values are changed. For example, in (a) of FIG. 7, the plurality of measurement positions P4 located in the same zone PA1 are divided into two zones PA2 different from each other. In a case where the zone PA1 corresponds to the first zone, the zone PA2 corresponds to the second zone. Figure 7

[0131] Next, the zone determination section 62 re-determines the zones PA corresponding to the measurement positions (process S44).

[0132] For example, the zone determination section 62 determines the zone PA2 corresponding to the measurement position among the plurality of zones PA2 re-set in the process S43. The zone determination section 62 determines the zone PA2 corresponding to the measurement position of each measurement value among the plurality of zones PA2 on the basis of the position information acquired in the position information acquisition section 31. The zone determination section 62 stores, for example, the determination result in the storage section 22. The zone determination section 62 can also output the determination result to the display information determination section 52.

[0133] ​Next, the display information determination unit 52 determines the representative value in zone PA (process S45). When process S45 ends, the zone resetting process ends. For example, the display information determination unit 52 determines the representative value corresponding to each of the multiple zones PA2 reset in process S43. The display information determination unit 52 obtains the measurement value corresponding to the target zone PA2 from the zone determination unit 62 or the storage unit 22. The display information determination unit 52 determines the representative value based on, for example, the measurement value corresponding to zone PA2. When two or more measurement values ​​measured at different times correspond to a zone PA2, the display information determination unit 52 calculates and determines the representative value using these two or more measurement values. In this case, in process S36 after process S45, the display information determination unit 52 determines information related to the display of zone PA2 based on the representative value calculated in process S45.

[0134] The above describes an example of a measurement method using an electromagnetic environment analysis system, but the order of each process is not limited to this. For example, process S1 can be executed at any time if it occurs after process S2 and before process S6. If process S1 is executed before process S33, it can be performed midway through process S6. When the resetting determination unit 63 determines the resetting of the zone PA based on the user's input operation, process S35 can be executed at any time if it occurs after process S1 and before process S36.

[0135] In process S31, information related to the electromagnetic environment is acquired from sensor 11, and multiple measurement values ​​are obtained based on the acquired information. Sensor 11 sequentially detects information related to the electromagnetic environment. In this embodiment, multiple measurement values ​​related to the electromagnetic environment are acquired in process S31 by repeatedly performing processes S3 to S7. Imaging unit 21 sequentially captures images of the actual space, and image acquisition unit 41 acquires the images sequentially captured by imaging unit 21. When multiple measurement values ​​are output from measurement processing unit 23 between one cycle of processes S3 to S7, multiple measurement values ​​are acquired in one process S31.

[0136] Next, refer to Figures 15 to 18 This section provides a more detailed example of the reclassification of zones in Electromagnetic Environment Analysis System 1. Figures 15 to 18 In this context, different colors are represented by different shades.

[0137] exist Figure 15 In this embodiment, by executing processes S31 to S37, information corresponding to the measured values ​​is displayed in each zone PA1 that forms the display range RA. In this embodiment, each zone PA1 is color-coded according to the measured values. Within the display range RA, zones PA1 without shading are areas that are not measured.

[0138] fromFigure 15 The state shown in FIG. 9, the measurement is repeatedly performed with the movement of the operation section 10. As a result, the number of the zones PA1 in which the information corresponding to the measurement value is displayed increases. In other words, the number of the zones PA1 in which the color is displayed increases. Figure 16 As shown in FIG. 10, the zones PA1 in which the information corresponding to the measurement value is displayed increase. In other words, the zones PA1 in which the color is displayed increase.

[0139] Further, from the state shown in FIG. 9, the measurement is repeatedly performed with the movement of the operation section 10. As a result, the number of the zones PA1 in which the information corresponding to the measurement value is displayed increases. In other words, the number of the zones PA1 in which the color is displayed increases. Figure 16 As shown in FIG. 9, the measurement is repeatedly performed with the movement of the operation section 10. As a result, the number of the zones PA1 in which the information corresponding to the measurement value is displayed increases. In other words, the number of the zones PA1 in which the color is displayed increases. Figure 17 As shown in FIG. 10, the zones PA1 in which the information corresponding to the measurement value is displayed increase. In other words, the zones PA1 in which the color is displayed increase. Figure 16 As shown in FIG. 9, the measurement is repeatedly performed with the movement of the operation section 10. As a result, the number of the zones PA1 in which the information corresponding to the measurement value is displayed increases. In other words, the number of the zones PA1 in which the color is displayed increases. Figure 16 As shown in FIG. 9, the measurement is repeatedly performed with the movement of the operation section 10. As a result, the number of the zones PA1 in which the information corresponding to the measurement value is displayed increases. In other words, the number of the zones PA1 in which the color is displayed increases.

[0140] Further, from the state shown in FIG. 9, the measurement is repeatedly performed with the movement of the operation section 10. As a result, the number of the zones PA1 in which the information corresponding to the measurement value is displayed increases. In other words, the number of the zones PA1 in which the color is displayed increases. Figure 17 As shown in FIG. 9, the measurement is repeatedly performed with the movement of the operation section 10. As a result, the number of the zones PA1 in which the information corresponding to the measurement value is displayed increases. In other words, the number of the zones PA1 in which the color is displayed increases. Figure 18 As shown in FIG. 10, the zones PA1 in which the information corresponding to the measurement value is displayed increase. In other words, the zones PA1 in which the color is displayed increase. Figure 17 As shown in FIG. 9, the measurement is repeatedly performed with the movement of the operation section 10. As a result, the number of the zones PA1 in which the information corresponding to the measurement value is displayed increases. In other words, the number of the zones PA1 in which the color is displayed increases. Figure 17The states shown are more finely distinguished. The determination of the representative values in the plurality of divisions PA3 is performed by the process S44 and the process S45, and the display within the display range RA is updated from the display based on the plurality of divisions PA2 to the display based on the plurality of divisions PA3 by the process S36 and the process S37.

[0141] Next, the effects of the electromagnetic environment analysis system in the present embodiment will be described. In the electromagnetic environment analysis system 1, the re-division determination section 63 determines whether to re-divide the plurality of divisions PA. In a case where the re-division determination section 63 determines to re-divide the plurality of divisions PA, the division setting section 61 re-divides the plurality of divisions PA forming the display range RA into a plurality of divisions PA2 smaller than the plurality of divisions PA1. In this case, the display information determination section 52 determines information related to the display of the plurality of divisions PA2. Thus, the size of the plurality of divisions PA forming the display range RA can be changed in the measurement of the display range RA. Therefore, the resolution of the display can be changed according to the situation of the measurement. As a result, the desired measurement can be easily achieved.

[0142] The size of each division PA2 is smaller than the size of each division PA1. In this case, in the measurement of the display range RA, the resolution of the display can be set from a low state to a high state. Thus, the electromagnetic environment analysis system 1 can display the measurement result of the rough position at the initial stage of the measurement, and then display the measurement result of the desired position in detail.

[0143] In a case where the re-division determination section 63 determines to re-divide the plurality of divisions PA, the division determination section 62 determines the division PA2 of the plurality of divisions PA2 corresponding to the measurement position of each measurement value based on the position information, and the display information determination section 52 determines the information related to the display of the division PA2 based on the measurement value corresponding to the division PA2. In this case, the measurement value corresponding to the division PA2 is re-determined, and thus more accurate display can be achieved in the division PA2.

[0144] In a case where at least one of the plurality of conditions is satisfied, the re-division determination section 63 determines to re-divide the plurality of divisions PA. In a case where a first condition of the plurality of conditions is satisfied, the size of each division PA2 re-divided by the division setting section 61 is smaller than in a case where a second condition of the plurality of conditions is satisfied. In this case, the plurality of divisions PA of the display range RA is re-divided into the divisions PA2 of different sizes according to the conditions. Thus, the desired measurement can be more easily achieved.

[0145] The second condition is a condition that is satisfied before the first condition is satisfied. In this case, the size of the plurality of divisions PA forming the display range RA by satisfying the second condition is further reduced by satisfying the first condition after the size of the plurality of divisions PA forming the display range RA by satisfying the second condition is set again. Thus, the resolution of the display can be changed in stages according to the measured condition.

[0146] The storage section 22 stores a plurality of division definition tables 71, 72 that define the structure of each division PA in the case where the display range RA is divided according to different numbers. The division setting section 61 sets the plurality of divisions PA based on the plurality of division definition tables 71, 72. In this case, the resolution of the display can be changed more easily by the division definition tables 71, 72 without special arithmetic processing.

[0147] The reset determination section 63 determines to reset the plurality of divisions PA according to the input operation of the user. In this case, the reset of the plurality of divisions PA can be performed at an arbitrary timing.

[0148] The reset determination section 63 determines to reset the plurality of divisions PA in the case where the number of divisions PA corresponding to the measured value exceeds a predetermined number. In this case, the reset of the plurality of divisions PA can be performed automatically.

[0149] The reset determination section 63 determines to reset the plurality of divisions PA in the case where the proportion of the number of divisions PA corresponding to the measured value to the number of divisions of the display range RA exceeds a predetermined value. In this case, the reset of the plurality of divisions PA can be performed automatically by simpler setting.

[0150] The reset determination section 63 prohibits the reset of the plurality of divisions PA in the case where the number of times of the reset of the plurality of divisions PA exceeds a predetermined number. In this case, the reset can be avoided from being performed more than necessary. As a result, the detailed measurement of the desired position can be achieved more easily.

[0151] When two or more measurement values measured at mutually different times correspond to one division PA, the electromagnetic environment analysis system 1 calculates a representative value from the two or more measurement values, and determines information related to display of the division PA based on the representative value. In this way, the electromagnetic environment analysis system 1 performs two-stage processing of calculation of a representative value and determination of display information based on the representative value, and thus can display appropriate measurement results for each division PA even when there are multiple measurement values for one division PA. For example, if movement of the sensor 11 and measurement by the sensor 11 are not synchronized, the measurement values and the divisions PA do not necessarily have a one-to-one relationship. Considering measurement error, there is also a need to take multiple measurements in one division PA. In this way, even when multiple measurements are taken in one division PA, the electromagnetic environment analysis system 1 can display appropriate measurement results for each division, for a device in which the time of measurement and the position of measurement are not synchronized.

[0152] The measurement information acquisition unit 34 acquires additional information corresponding to each measurement value. The additional information includes at least one of information related to the intensity of an electromagnetic wave, information related to the phase of an electromagnetic wave, information related to the frequency component of an electromagnetic wave, and information related to the time of measurement. The display information determination unit 52 calculates a representative value from two or more measurement values included in one division PA based on the additional information. In this case, a more appropriate representative value can be calculated from two or more measurement values.

[0153] The multiple measurement values can include multiple measurement values related to electromagnetic waves of mutually different frequency components. In this case, the display information determination unit 52 selects at least one measurement value from the two or more measurement values based on the frequency component, and calculates a representative value from the selected at least one measurement value. As a result, in the case where there are two or more measurement values in one division PA, an appropriate measurement result related to an electromagnetic wave of a desired frequency component can be displayed.

[0154] The multiple measurement values can include multiple first measurement values related to electromagnetic waves of a first frequency component and multiple second measurement values related to electromagnetic waves of a second frequency component. In this case, the display information determination unit 52 determines first information related to display of a division PA based on first measurement values corresponding to the division PA, and determines second information related to display of the division PA based on second measurement values corresponding to each division PA. When two or more first measurement values measured at mutually different times correspond to one division PA, the display information determination unit calculates a first representative value from the two or more first measurement values, and determines the first information related to display of the division PA based on the first representative value. As a result, for each electromagnetic wave of a different frequency component, an appropriate measurement result can be displayed in each division PA.

[0155] The display information determination section 52 determines information related to the display of the zone PA by setting a maximum value, a minimum value, a median value, or a mode of two or more measurement values included in one zone PA as a representative value. In this case, a desired measurement value can be set as the representative value. For example, the measurement result can be displayed more accurately compared to a case where only the measurement values in the same zone PA are updated.

[0156] The display information determination section 52 can also determine information related to the display of the zone PA by calculating an average value of two or more measurement values included in one zone PA, and setting the calculated average value as a representative value. In this case, a desired measurement value can also be set as the representative value.

[0157] The image production section 35 also includes a re-setting determination section 63 that determines whether to re-set the plurality of zones PA that form the display range RA. In a case where the re-setting determination section 63 determines to re-set the plurality of zones PA, the zone setting section 61, the zone determination section 62, and the display information determination section 52 perform the following processing. The zone setting section 61 re-sets the plurality of zones PA that form the display range RA from the plurality of zones PA1 to a plurality of zones PA2 each having a different size from the zones PA1. The zone determination section 62 determines the zone PA2 in the plurality of zones PA2 that corresponds to the measurement position P4 of each measurement value based on the position information acquired by the position information acquisition section 31. The display information determination section 52 can also determine information related to the display of the zone PA2 based on the measurement value corresponding to the zone PA2.
