[Technical field]

[0001] The present invention relates to a measuring terminal device, a tilt measuring method, and a program. [Background technology]

[0002] One element of the damage assessment survey for the purpose of issuing a disaster damage certificate is the assessment of damage based on the inclination of a house, etc. Generally, when measuring the inclination of a house, etc., an investigator uses a tool called a plumb bob.

[0003] The problems that may arise when an inspector uses a plumb bob to measure the inclination of a house or other structure include the following (1) to (3).

[0004] (1) When measuring the inclination of a dwelling, etc., two or more people are required, one to fix the plumb line and one to check the measurement value.

[0005] (2) A plumb bob is not a commonly used tool, and there are learning costs involved, such as learning how to use it and learning the criteria for judging the extent of damage based on the inclination of a house or other structure.

[0006] (3) Immediately after a large-scale disaster, there may be a shortage of plumb bobs, and it may be necessary to use substitutes to measure the inclination of houses, etc. If substitutes are used, there is a concern that the reliability of the measurement data may decrease.

[0007] Meanwhile, a technology is known in which application software installed on a smart device is executed and the smart device is used to measure the inclination angle of a building. Non-Patent Document 1 describes that during a damage certification survey, application software on a smart device is used to measure the inclination angle of a building and to photograph the measurement results.

[0008] Patent Document 1 describes a technology for determining the degree of damage to buildings. In this document, an acceleration sensor built into a smart device, a personal computer, or the like is given as an example of a sensor for detecting the acceleration of an earthquake.

[0009] Patent Document 2 describes a sensor module that uses two acceleration sensors to measure changes in gravitational acceleration and measures the tilt angle of an object using the measurement data from the acceleration sensors. The document also describes that an acceleration sensor of a smart device such as a mobile phone can be used as the sensor module.

[0010] Non-Patent Document 1 describes the specific procedures and investigation methods for damage certification investigations. Damage certification investigations are carried out based on the descriptions in this document. [Prior art documents] [Patent documents]

[0056] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification, the same components are designated by the same reference numerals, and duplicated descriptions will be omitted as appropriate.

[0057] [Summary of damage certification investigation] For houses and other structures damaged by disasters such as earthquakes, a damage assessment survey is conducted to investigate the damage to the house, etc., as a prerequisite for the issuance of a disaster certificate certifying the extent of the damage. The damage assessment survey includes measuring the four corners of the exterior walls of the first floor of the house, or the pillars at the four corners, and deriving the simple average inclination.

[0058] Fig. 1 is a schematic diagram of wall inclination measurement. The figure shows a state in which an inspector P is using a measurement terminal device 10 to measure the inclination of a wall 20, which is an exterior wall of a dwelling 1 to be inspected.

[0059] Fig. 2 is an explanatory diagram showing specific examples of the four main corners of the surveyed house. The figure shows a plan view of the surveyed house 1. The figure shows examples of corners 22 that are the four main corners of the surveyed house 1.

[0060] Fig. 3 is an explanatory diagram showing examples of the four main corners. The figure shows a top view of the surveyed dwelling house 1. Each of corners 22A, 22B, 22C, and 22D shown in the figure is an example of corners 22 that make up the four main corners. The arrows attached to each of corners 22A, 22B, 22C, and 22D in Fig. 3 indicate the inclination of each of corners 22A, 22B, 22C, and 22D.

[0061] Figure 4 is an explanatory diagram showing the installation state of a measurement terminal device on a wall to be measured. The wall 20 shown in Figure 4 is one of two walls constituting any one of the four main corners. The measurement terminal device 10 used by the surveyor P shown in Figure 1 has inclination measurement application software installed, and the surveyor P brings the measurement terminal device 10 into contact with the wall 20 to be measured, runs the inclination measurement application software, and performs an inclination measurement to measure the angle θ of the wall 20 with respect to the vertical direction.

[0062] Fig. 4 shows an example in which the back surface of the measuring terminal device 10 is placed against a wall 20 and the inclination of the wall 20 with respect to the vertical direction is measured. The two dashed dotted lines shown in Fig. 4 represent two perpendicular directions on a horizontal plane. Also, the dashed dotted line perpendicular to the two dashed dotted lines representing the horizontal plane shown in the figure represents the vertical direction.

[0063] The back surface of the measuring terminal device 10 is the surface opposite to the front surface on which the display 102 of the measuring terminal device 10 is mounted. In Fig. 4, the reference numerals for the back surface of the measuring terminal device 10 are omitted. The back surface of the measuring terminal device 10 is shown in Fig. 9 with the reference numeral 10B.

[0064] When the side of the measuring terminal device 10 is installed against the wall 20, the installation state of the measuring terminal device 10 against the wall 20 becomes unstable, making it difficult to accurately measure the inclination of the wall 20. Note that the side of the rectangular parallelepiped measuring terminal device 10 is the two relatively long faces between the front and back faces.

[0065] On the other hand, when the back surface of the measuring terminal device 10 is placed against the wall 20 as shown in FIG. 4, the measuring terminal device 10 is placed in a stable state against the wall 20, and the inclination of the wall 20 can be measured accurately.

[0066] 5 is a schematic diagram of two walls constituting a corner viewed vertically from above. In measuring the inclination of the four main corners of the measurement subject house, the degree of inclination of each of the two walls 20A and 20B constituting the corner 22 is measured.

[0067] The degree of inclination of wall 20A and the degree of inclination of wall 20B are added together as a vector to calculate the inclination value of corner 22. In most homes, the angle between walls 20A and 20B that make up corner 22 can be approximated as a right angle. The inclination of walls 20A and 20B that make up corner 22 can be derived by applying Pythagoras' theorem using their respective tangent values.

[0070] The measurement terminal device 10 includes a power button 110 and an operation button 112. The power button 110 and the operation button 112 are mounted on one side of the frame 100. The measurement terminal device 10 includes an input / output port 120. The input / output port 120 is built into the frame 100.

[0071] A detachable liquid crystal panel is applied as the display 102. Various information and software buttons are displayed on the display 102. The display 102 functions as a display device and an operating device.

The speaker 106 converts the electrical signals into sounds and outputs the sounds representing the electrical signals. The camera 108 converts optical images into electrical signals and generates electrical signals representing the optical images. The electrical signals representing the optical images are called images and image signals.

[0073] The power button 110 outputs an electrical signal indicating power on and an electrical signal indicating power off in response to an operation by an operator. The operation button 112 outputs an electrical signal indicating display 102 on and an electrical signal indicating display 102 off in response to an operation by an operator.

[0074] Fig. 7 is a functional block diagram of the measuring terminal device shown in Fig. 6. The measuring terminal device 10 includes one or more processors 200 and one or more memories 202. The processor 200 executes a program to realize various functions of the measuring terminal device 10. Each unit included in the processor 200 shown in Fig. 7 corresponds to various functions realized by the processor 200.

[0075] The memory 202 stores various data applied to the measurement terminal device 10. The memory 202 stores various data applied to the measurement terminal device 10. The memory 202 may be a semiconductor storage medium such as a Read Only Memory (ROM) and a Random Access Memory (RAM). The memory 202 may be a magnetic storage medium such as a hard disk.

[0076] The measuring terminal device 10 includes an acceleration sensor 204. A three-axis acceleration sensor that measures acceleration in three mutually orthogonal directions is applied to the acceleration sensor 204. A signal representing measurement data output from the acceleration sensor 204 is transmitted to the processor 200.

[0077] The processor 200 includes a dwelling information acquisition unit 219. The dwelling information acquisition unit 219 acquires dwelling information related to the dwelling to be surveyed, such as the address and structure of the dwelling to be surveyed, transmitted from outside the measuring terminal device 10 via the input / output port 120. The dwelling information is stored in the memory 202. Note that the dwelling described in the embodiment is an example of a structure. The address described in the embodiment is an example of geographical location information indicating a geographical location.

[0078] The processor 200 includes an installation properness confirmation unit 220. The installation properness confirmation unit 220 acquires the measurement data transmitted from the acceleration sensor 204, and causes the display 102 to display the measurement data of the acceleration sensor 204.

[0079] The installation suitability confirmation unit 220 detects the attitude of the measuring terminal device 10 based on the measurement data of the acceleration sensor 204, and displays the attitude of the measuring terminal device 10 on the display 102. The surveyor checks the measurement data of the acceleration sensor 204 displayed on the display 102 and the attitude of the measuring terminal device 10, and can adjust the attitude of the measuring terminal device 10 to be parallel to the horizontal direction by aligning any one axis of the acceleration sensor 204 provided in the measuring terminal device 10 with the horizontal direction.

[0080] That is, the installation suitability confirmation unit 220 displays the measurement value of the acceleration sensor 204 and the attitude of the measuring terminal device 10 with respect to the horizontal direction as first assist information for assisting the installation of the measuring terminal device 10 on the wall 20. The attitude of the measuring terminal device 10 with respect to the horizontal direction is determined by the angle of any one axis of the acceleration sensor 204 with respect to the horizontal direction.

[0081] The processor 200 includes an inclination calculation unit 222. The inclination calculation unit 222 acquires measurement data from the acceleration sensor 204, and calculates an inclination index value representing the inclination of the wall 20 to be measured with respect to the vertical direction based on the measurement data from the acceleration sensor 204. The inclination calculation unit 222 stores the calculation result for each wall 20 in the memory 202. The inclination calculation unit 222 causes the calculation result for each wall 20 to be displayed on the display 102.

[0082] The inclination calculation unit 222 calculates inclination index values ​​for the two walls 20A and 20B that constitute the corner 22 shown in Figure 2 for each of the four main corners of the house being surveyed, and calculates the inclination value for each corner 22 based on the inclination index values ​​of walls 20A and 20B.

[0083] The inclination calculation unit 222 stores the inclination value calculated for each corner 22 in the memory 202. The inclination calculation unit 222 causes the inclination value for each corner 22 to be displayed on the display 102.

[0084] The processor 200 includes a damage level determination unit 224.

The damage level determination unit 224 stores the damage level determination result in the memory 202.

[0085] The processor 200 receives signals transmitted from the power button 110 and the operation button 112, and operates each part of the measurement terminal device 10 in response to the received signals. The processor 200 acquires an audio signal transmitted from the microphone 104, converts the received audio signal into a wireless signal conforming to a prescribed standard, and transmits the wireless signal to the outside.

[0086] The speaker 106 receives an audio signal transmitted from the processor 200, converts the received audio signal into sound, and outputs the sound. Note that the sound referred to here may include an alarm sound, a beep sound, and the like.

[0087] The camera 108 converts an optical image representing an object into an electrical signal to generate an image of the object.

Here, the term image can include the meaning of the image itself and image data, which is an electrical signal representing the image.

[0088] [Hardware configuration of various processing units and various control units] The hardware of the processing unit that performs various processes may be implemented using various processors. The processing unit may be called a processing unit. The various processors include a CPU (Central Processing Unit), a PLD (Programmable Logic Device), and an ASIC (Application Specific Integrated Circuit).

[0089] A CPU is a general-purpose processor that executes programs and functions as various processing units. A PLD is a processor whose circuit configuration can be changed after manufacturing. An example of a PLD is the Field Programmable Gate Array (FPGA). An ASIC is a dedicated electrical circuit with a circuit configuration designed specifically to perform a specific process.

[0090] A single processing unit may be configured with one of these various processors, or may be configured with two or more processors of the same or different types. For example, a single processing unit may be configured using multiple FPGAs, etc. A single processing unit may be configured by combining one or more FPGAs and one or more CPUs.

[0091] In addition, multiple processing units may be configured using one processor. As an example of using one processor to configure multiple processing units, one processor may be configured by combining one or more CPUs and software, and the single processor may function as multiple processing units. This type of configuration is typified by computers such as client terminal devices and server devices.

[0092] Another example of the configuration is a form that uses a processor that realizes the functions of the entire system including multiple processing units using a single IC chip. This form is typified by system on chip. Note that IC is an abbreviation for integrated circuit. Also, system on chip is sometimes written as SoC, which is an abbreviation for system on chip.

[0093] In this way, the various processing units are configured as a hardware structure using one or more of the various processors described above. More specifically, the hardware structure of the various processors is an electric circuit (circuitry) that combines circuit elements such as semiconductor elements.

[0094] [Wall inclination measurement method procedure] 8 is a flowchart showing the procedure of the damage level determination method according to the embodiment. An investigator P shown in FIG. 1 operates the measurement terminal device 10 and executes a program applied to damage level determination using the processor 200 shown in FIG.

[0095] In the dwelling information acquisition step S10, the processor 200 acquires dwelling information on the dwelling to be surveyed. The processor 200 may acquire dwelling information input by the inspector P operating the measurement terminal device 10, or may acquire dwelling information stored in advance. After the dwelling information acquisition step S10, the process proceeds to the device installation step S12.

[0096] In the device installation step S12, the installation suitability confirmation unit 220 shown in FIG. 5 detects the orientation of the measuring terminal device 10 with respect to the wall 20 to be measured, and causes the display 102 to display the orientation of the measuring terminal device 10.

[0097] The surveyor installs the measurement terminal device 10 by contacting the back surface 10B, which is the wide surface of the measurement terminal device 10, with the wall 20 to be measured. The surveyor should contact the entire back surface 10B of the measurement terminal device 10 with the wall 20 to be measured. After the device installation step S12, the process proceeds to the installation adjustment step S14.

[0098] In addition, the detection of the attitude of the measuring terminal device 10 in the device installation step S12 described in the embodiment is an example of terminal attitude detection that detects whether the inclination of the measuring terminal device with respect to the horizontal direction in a plane parallel to the wall of the measurement target is within a specified range. Also, the display of the attitude of the measuring terminal device 10 on the display 102 in the same step is an example of displaying the third assist information on the display device.

[0099] In the installation adjustment step S14, the installation suitability confirmation unit 220 adjusts the installation state of the measuring terminal device 10. In the installation adjustment step S14, the installation suitability confirmation unit 220 causes the display 102 to display first assist information that assists in the installation of the measuring terminal device 10 on the wall 20.

[0100] The surveyor P can manually adjust the attitude of the measuring terminal device 10 to be parallel to the horizontal direction by referring to the first assist information displayed on the display 102. After the installation adjustment step S14, the process proceeds to the tilt measurement step S16. Note that the detection of the installation state of the measuring terminal device 10 in the installation adjustment step S14 described in the embodiment is an example of terminal tilt detection.

[0101] In the inclination measurement step S16, the inclination calculation unit 222 acquires measurement data from the acceleration sensor 204, and calculates an inclination index value of the wall 20 to be measured with respect to the vertical direction based on the measurement data from the acceleration sensor 204. Note that the calculation of the inclination index value of the wall 20 in the inclination measurement step S16 described in the embodiment is an example of wall inclination measurement.

[0102] Further, the inclination calculation unit 222 calculates the inclination value of the corner 22 based on the inclination index value of the wall 20, and stores the inclination value for each corner 22. In the inclination measurement step S16, second assist information that assists in measuring the inclination of the wall 20 is displayed on the display 102. The second assist information will be described in detail later. After the inclination measurement step S16, the process proceeds to a step S18 of determining whether or not measurement of all points has been completed.

[0103] In the all-points measurement completion determination process S18, the inclination calculation unit 222 determines whether or not inclination values ​​have been obtained for the four main corners of the house being surveyed. If the inclination calculation unit 222 determines that there is a corner 22 for which no inclination value has been obtained in the all-points measurement completion determination process S18, the determination is No. If the determination is No, the process proceeds to the device installation process S12, and each of the device installation process S12 to the all-points measurement completion determination process S18 is repeatedly performed until the determination is Yes in the all-points measurement completion determination process S18.

[0104] On the other hand, if the inclination calculation unit 222 determines that the inclination values ​​have been obtained for all of the four main corners in the all-point measurement completion determination step S18, the determination is Yes. If the determination is Yes, the process proceeds to the damage level determination step S20.

[0105] In the damage level determination step S20, the damage level determination unit 224 derives a damage level determination result for the house to be surveyed based on the inclination values ​​of the four main corners. The damage level determination unit 224 stores the damage level determination result in the memory 202. The damage level determination unit 224 causes the display 102 to display the damage level determination result.

[0106] When the damage level determination result for the surveyed house is derived in the damage level determination step S20, the processor 200 ends the procedure of the damage level determination method. Each step from the house information acquisition step S10 to the all-point measurement completion determination step S18 described in the embodiment is an example of a component of the inclination measurement method.

[0107] [Detailed explanation of wall inclination measurement] Next, the inclination measurement of the wall 20 performed using the measuring terminal device 10 will be described in detail. Fig. 9 is an explanatory diagram of axes applied to the measuring terminal device. α, β, and γ shown in Fig. 9 represent the three axes that can be measured by the acceleration sensor 204 shown in Fig. 7.

[0108] In a plane parallel to the front surface 10A and the back surface 10B of the measuring terminal device 10, one of two mutually orthogonal axes is defined as an α-axis, and the other is defined as a β-axis. The axis perpendicular to the front surface 10A and the back surface 10B is defined as a γ-axis.

[0109] In the installation adjustment process S14 shown in FIG. 8, when the measuring terminal device 10 is installed on the wall 20, the measuring terminal device 10 is adjusted to a posture in which the measurement value of the α-axis of the acceleration sensor 204 is zero and the α-axis of the acceleration sensor 204 is aligned with the horizontal direction.

[0110] Fig. 10 is an explanatory diagram of wall inclination measurement. Fig. 11 is a diagram of Fig. 10 viewed from the front of the wall. The acceleration sensor 204 provided in the measuring terminal device 10 detects the β-axis component g β and the γ-axis component of the gravitational acceleration g γ In the above-mentioned adjustment of the attitude of the measuring terminal device 10, the α-axis component g of the gravitational acceleration g is measured. α is adjusted to zero. If the angle that the wall 20 makes with respect to the vertical direction is θ, then tan θ=g β / g γ That is, the angle θ represents the inclination of the wall 20 with respect to the vertical direction.

[0111] The measuring terminal device 10 can accurately calculate the inclination index value of the wall 20 by distributing the gravitational acceleration g acting on the acceleration sensor 204 into the β-axis direction, which is a component perpendicular to the intersection line between the wall 20 and a plane parallel to the horizontal plane within the plane of the wall 20, and the γ-axis direction, which is the normal direction of the wall 20.

[0112] For convenience of illustration, the β-axis component of the gravitational acceleration g is β and the γ-axis component of the gravitational acceleration g γ Although the vectors are shown as parallel vectors with different starting points, they are actually parallel vectors with the same starting point. Similarly, the γ-axis component g of the gravitational acceleration g shown in FIG. γ and the α-axis component of gravitational acceleration g α and the β-axis component of the gravitational acceleration g β The composite vector of and is also a parallel vector with the same starting point.

[0113] 12 is an explanatory diagram of a case where the attitude of the measuring terminal device 10 is not adjusted with respect to the horizontal direction. In the installation adjustment step S14, when the attitude of the measuring terminal device 10 is not adjusted so that the α-axis of the acceleration sensor 204 coincides with the horizontal direction, the acceleration sensor 204 detects the α-axis component g α A non-zero value is obtained as the measured value of .

[0114] When calculating the inclination index value of the wall 20, the α-axis component g of the gravitational acceleration g α and the β-axis component of the gravitational acceleration g β The component of the gravitational acceleration g in the direction parallel to the surface 10A of the measurement terminal device is calculated by combining these, and the α-axis component g of the gravitational acceleration g is calculated. α and the β-axis component of the gravitational acceleration g β The combined component of and the γ-axis component of the gravitational acceleration g γ is used to derive the angle θ that the wall 20 makes with respect to the vertical direction.

[0115] That is, when the attitude of the measuring terminal device 10 is adjusted so that the α axis of the acceleration sensor 204 coincides with the horizontal direction, the α-axis component g of the gravitational acceleration g is smaller than when the attitude of the measuring terminal device 10 is not adjusted so that the α axis of the acceleration sensor 204 coincides with the horizontal direction. α and the β-axis component of the gravitational acceleration g β This eliminates the need for a process of synthesizing the above-mentioned signal and the above-mentioned signal, thereby reducing the computation load.

[0116] [Specific examples of assist displays applied to measuring terminal devices] 13 to 17, the assist information applied to the measuring terminal device 10 will be described. The assist information assists the damage assessment survey of the survey target dwelling carried out using the measuring terminal device 10, the calculation of the inclination values ​​of the four main corners in the damage assessment survey, and the inclination measurement of the wall 20. The assist information is displayed on the display 102.

[0117] Fig. 13 is a front view of the display on which the investigation in progress screen is displayed. Fig. 13 shows an investigation in progress screen 300 which indicates that a damage certification investigation is in progress. The investigation in progress screen 300 includes address information 302 which indicates the address of the dwelling to be investigated, and structure information 304 which indicates the structure of the dwelling to be investigated.

[0118] The address information 302 may be a residential address including administrative divisions such as prefectures and cities, wards, towns, and villages. The structure information 304 may be a building structure such as a wooden structure or a reinforced concrete structure. The address information 302 and the structure information 304 are character information.

[0119] The survey in progress screen 300 also includes main corner information 306 that shows the main four corners of the house being surveyed in a schematic manner, measurement data information 308 that shows the measurement data of the main four corners, and operation buttons 310.

[0120] The corner where the number 1 in the main four corner information 306 is displayed corresponds to the corner 22A shown in Fig. 3. The corners where the numbers 2, 3, and 4 in the main four corner information 306 are displayed correspond to the corners 22B, 22C, and 22D shown in Fig. 3.

[0121] The main four corners information 306 is displayed in inverted form for the corners 22 for which measurement data was obtained. Furthermore, for the corners 22 for which measurement data was obtained, arrows that typically represent the measurement data and values ​​of the measurement data are added to the main four corners information 306. Note that the main four corners information 306 described in the embodiment is an example of measurement position information that represents the position of the wall to be measured.

[0122] Measurement data information 308 displays the measurement data for each of the four main corners. The measurement data for the first corner corresponds to the measurement data for the corner marked with the number 1 in main corner information 306. The measurement data for the second corner, the measurement data for the third corner, and the measurement data for the fourth corner correspond to the measurement data for the corners marked with the numbers 2, 3, and 4 in main corner information 306, respectively.

[0123] The operation buttons 310 include four buttons corresponding to the four major corners. The operation buttons 310 include a button for instructing the start of a measurement. The operation buttons 310 may include a button for instructing the start of a remeasurement for the corner 22 for which measurement data was obtained.

[0124] The operation button 310 described in the embodiment is an example of a third button that instructs the execution of a wall inclination measurement for the wall to be measured, and is an example of a fourth button that instructs the execution of a wall inclination measurement again for a wall to be measured that has already been measured.

[0125] Fig. 14 is a front view of a display on which the judgment result display screen is displayed. The judgment result display screen 320 shown in the figure assists in the damage certification survey of the survey target dwelling. The judgment result display screen 320 adds judgment result information 322 to the survey in progress screen 300 shown in Fig. 13. Fig. 14 illustrates the judgment result display screen 320 on which text information indicating total destruction is displayed as the judgment result information 322.

[0126] When an operation button 310 for commanding execution of wall inclination measurement or execution of remeasurement of wall inclination measurement is operated on the investigation execution screen 300 shown in Fig. 13 and the determination result display screen 320 shown in Fig. 14, an assist display for assisting the wall inclination measurement is displayed on the display 102. The various pieces of information shown in Fig. 13 and Fig. 14 are examples of second assist information.

[0127] 15 is a front view of a display on which an installation adjustment screen is displayed. This figure shows an installation adjustment screen 340 that assists in proper installation of the measuring terminal device 10 in measuring the inclination of the wall 20. The installation adjustment screen 340 includes an attitude line 342 that indicates the attitude of the measuring terminal device 10, an angle scale 344, a horizontal reference line 346, and operation information 348.

[0128] When wall inclination measurement is started and the measuring terminal device 10 is placed on the wall 20 to be measured, the measuring terminal device 10 acquires measurement data from the acceleration sensor 204, generates a posture line 342 based on the measurement data of the α-axis component shown in FIG. 9, and displays the posture line 342 on the display 102.

[0129] The inspector P can refer to the posture line 342 , the angle scale 344 and the horizontal reference line 346 and adjust the posture of the measurement terminal device 10 to a posture that aligns the posture line 342 with the horizontal reference line 346 .

[0130] The operation information 348 is applied as text information expressing the operation content of the measurement terminal device 10 for the inspector P. The inspector P can understand the operation content of the measurement terminal device 10 in the installation adjustment process S14 by referring to the operation information 348.

[0131] 16 is a front view of the display on which the measurement in progress screen is displayed. When the state in which the posture line 342 and the horizontal reference line 346 are aligned continues for a certain period of time, the measurement terminal device 10 starts measuring the inclination of the wall 20 and acquires the measurement data of the acceleration sensor 204.

[0132] During the period from when the inclination measurement of the wall 20 is started until the measurement data of the acceleration sensor 204 is acquired, a measurement in progress screen 360 is displayed on the display 102. The measurement in progress screen 360 includes status information 362 indicating that measurement is in progress, instead of the operation information 348 in the installation adjustment screen 340 shown in FIG.

[0133] During the period when the measurement in progress screen 360 is displayed, if the attitude of the measurement terminal device 10 is changed to an attitude where the attitude line 342 does not coincide with the horizontal reference line 346, the measurement is stopped and status information 362 indicating that the measurement has been stopped may be displayed.

[0134] 17 is a front view of the display on which the measurement completion screen is displayed. When the measurement of the inclination of the wall 20 is completed and the measurement data is acquired, the measurement terminal device 10 causes the display 102 to display a measurement completion screen 380.

[0135] The measurement completion screen 380 includes status information 362A indicating that measurement is completed, instead of the status information 362 in the measurement in progress screen 360 shown in Fig. 15. The measurement completion screen 380 also includes measurement data value information 382, ​​a first button 384, and a second button 386.

[0136] 17 is applied as the button operated by the investigator P when performing remeasurement. When the investigator P operates the first button 384, the measurement terminal device 10 performs remeasurement.

[0137] The second button 386 is applied as a button that the investigator P operates when saving the measurement data. When the investigator P operates the second button 386, the measurement terminal device 10 saves the measurement data. Note that saving the measurement data here is synonymous with storing the measurement data.

[0138] 16 and 17 in the embodiment are an example of the second assist information. The second button 386 in the embodiment is an example of the first button for instructing storage of the measurement result of the wall inclination measurement.

[0139] [Results of damage assessment investigation] Figure 18 is an explanatory diagram of the judgment result. In the inclination measurement using a plumb bob, the horizontal distance d1 at the top end of the plumb bob and the horizontal distance d2 at the bottom end of the plumb bob are measured when the vertical length h of the plumb bob is 1200 mm, and the inclination index value is calculated by substituting the measured values ​​of d1 and d2 into (d1-d2) / 1200. Note that d in Figure 18 is d1-d2.

[0140] The judgment result information 322 shown in Fig. 14 converts the inclination values ​​of the corners 22 constituting the four major corners into d / h or d shown in Fig. 18, and displays the judgment result derived by comparing with the judgment criterion. The measurement data information 308 shown in Fig. 14 may convert the inclination values ​​of the corners 22 into d / h or d and display them.

[0141] [Effects of the measuring terminal device and wall inclination measuring method] The measuring terminal device and the wall inclination measuring method according to the embodiment can provide the following advantageous effects.

[0142] [1] In the installation adjustment step S14 of the measuring terminal device 10, an installation adjustment screen 340 is displayed on the display 102. The installation adjustment screen 340 includes, as the first assist information, an attitude line 342 and a horizontal reference line 346 that indicate the attitude of the measuring terminal device 10. This allows the investigator P to refer to the installation adjustment screen 340 and properly install the measuring terminal device 10 by aligning one axis of the acceleration sensor 204 with the horizontal direction. Furthermore, the investigator P can refer to the first assist information and determine whether the attitude of the measuring terminal device 10 should be maintained or changed.

[0143] [2] By properly installing the measuring terminal device 10 so that one axis of the acceleration sensor 204 coincides with the horizontal direction, one of the three axes of the acceleration sensor is fixed, and the inclination of the wall 20 to be measured can be calculated based on the measurement data of the remaining two axes. This makes the measurement data of the fixed axis unnecessary when the wall 20 to be measured is inclined, reduces the calculation load, and contributes to deriving an accurate inclination.

[0144] [3] The measurement terminal device 10 displays a measurement-in-progress screen 360 on the display 102 while measuring the inclination of the wall 20. This allows the surveyor P to understand that the inclination of the wall 20 is being measured.

[0145] [4] Upon completion of the inclination measurement of the wall 20, the measurement terminal device 10 displays a measurement completion screen 380 on the display 102. This allows the surveyor P to know that the inclination measurement of the wall 20 has been completed.

[0146] [5] The measurement terminal device 10 displays a survey in progress screen 300 on the display 102. The survey in progress screen 300 includes the address of the surveyed dwelling, the concept, information on the corner 22 of the measurement target, and the measurement data. This allows the surveyor P to grasp various information on the surveyed dwelling.

[0147] [6] An operation button 310 is displayed on the in-survey screen 300. This allows the surveyor P to instruct the measurement terminal device 10 to carry out a function assigned to the operation button 310 during wall inclination measurement.

[0148] [7] Measurement and re-measurement are assigned to the operation button 310. This allows the surveyor P to instruct the measurement terminal device 10 to carry out measurement and re-measurement.

[0149] [8] The measurement terminal device 10 displays a judgment result display screen 320 on the display 102. The judgment result display screen 320 includes judgment result information 322 that indicates the judgment result. This allows even an investigator P who is not familiar with the investigation method to accurately conduct a damage certification investigation.

In the damage certification investigation system 400 shown in the figure, a plurality of measurement terminal devices 10 and a server device 412 installed in an investigation headquarters 410 are connected via a network 402.

[0151] The network 402 may be the Internet, a wide area network, or the like. The network 402 shown in the figure may include a plurality of networks. Various communication standards may be applied to the network 402.

[0152] The measuring terminal device 10 can transmit various data in the damage assessment survey of the surveyed dwelling 1 to the server device 412 via the network 402. The server device 412 can obtain various data in the damage assessment survey transmitted from the measuring terminal device 10 and create a questionnaire for each surveyed dwelling 1.

[0153] The server device 412 may store various data and survey forms in the damage certification survey for each house 1 in a database 414 installed in the survey headquarters 410. The server device 412 and the database 414 may be installed outside the survey headquarters 410 and communicatively connected to a computer provided in the survey headquarters 410. The server device 412 and the database 414 may employ cloud computing.

[0154] [Examples of application to programs] A computer may be configured with a program that realizes various functions of the measuring terminal device 10. That is, a computer may be configured with a program that realizes a house information acquisition function, a function for confirming proper installation of the measuring terminal device 10, a tilt measurement function, a tilt value derivation function, and a damage degree determination function.

[0155] A program that causes a computer to realize the various functions described above can be stored in a computer-readable information storage medium, which is a tangible, non-transitory information storage medium, and the program can be provided through the information storage medium.

[0156] Further, instead of providing the program by storing it on a non-transitory information storage medium, a program signal may be provided via a communication network.
