Description

Technical Field

[0001] This disclosure relates to an image measuring apparatus and program that captures an image of a measured object, analyzes the image, and measures the dimension of a measurement point of the measured object. Background Technology

[0002] An image measuring apparatus is a device that captures an image of a measured object and measures the dimensions of measurement points of that object by analyzing the image (see, for example, JP2010-169584A). The image measuring apparatus performs measurements through a series of steps: specifying the element of interest or dimension in the captured image of the measured object, obtaining the measured values, setting the display mode and tolerance for these values, and saving the measurement results that reflect these settings. Summary of the Invention

[0003] The problem to be solved

[0004] Although various functions are implemented in the image measurement device to perform the aforementioned series of measurement processes, operators unfamiliar with the device may not easily understand the next step required at each stage of the measurement. Furthermore, while it is possible to consult the operation manual to recall forgotten functions or operations, this verification task increases the operator's burden and reduces work efficiency.

[0005] The embodiments of the present invention were made in view of the above-mentioned problems, and their object is to provide an image measurement apparatus and program that enables the operator to easily understand the next operation to be performed during the measurement operation.

[0016] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description and drawings, the same reference numerals are used for the same functional parts, and descriptions of functional parts that have already been described are omitted or described only to the extent necessary.

[0017] Figure 1 This is a schematic diagram showing an example of the appearance of the image measuring device 1. Figure 2 This is a schematic diagram showing the internal structure of the image measuring device 1. Figure 3 A functional block diagram of the image measuring device 1 is shown. In this embodiment, coaxial incident illumination will be used as an example to illustrate the case where an image of the object being measured can be captured. However, any illumination method is acceptable as long as an image of the object being measured can be captured.

[0018] The image measuring device 1 includes a mounting platform 2, an image capture unit 3, a control and processing unit 4, a storage unit 5, a display unit 6, a telecentric optical system 7, an illumination unit 8, and an input unit 10.

[0019] Mounting platform 2 is a platform on which the object to be measured, W, is placed.

[0020] Image capture unit 3 is positioned opposite to mounting stage 2 and captures an image of the measurement object W mounted on mounting stage 2 by receiving light from the direction of mounting stage 2. Image capture unit 3 includes an image sensor that converts the brightness or darkness of the image formed on its light-receiving surface into an electrical signal, thereby generating image data. For the image sensor, a semiconductor solid-state imaging device such as CCD (charge-coupled device) or CMOS (complementary metal-oxide-semiconductor) is used.

[0021] Storage unit 5 is any storage component capable of storing digital data.

[0022] Display unit 6 is any display component, and displays images of the measured object W captured by image capture unit 3, etc.

[0023] The telecentric optical system 7 includes an objective lens 71 that collects light from the direction of the mounting stage 2 and an imaging lens 72 that forms an image of the light arriving through the objective lens 71 on the light receiving surface of the image capturing unit 3. The objective lens 71 and the imaging lens 72 may each have multiple lens surfaces.

[0024] The illumination unit 8 is a coaxial incident illumination component, which includes a light source 81 that emits illumination light and a beam splitter 82. The beam splitter 82 splits the illumination light from the light source 81 into the telecentric optical system 7 and guides the light onto the coaxial incident illumination light guide mounting stage 2, whose optical axis coincides with the optical axis of the image capture unit 3. In addition to coaxial incident illumination, the illumination unit 8 can also be equipped with transmitted illumination or oblique illumination for image clarity and other purposes.

[0025] The input unit 10 accepts input from the operator. The input unit 10 may be configured, for example, as a touch panel display integrated with the display unit 6. Alternatively, in addition to or replacing a touch panel display, the input unit 10 may be equipped with a mouse.

[0026] The control processing unit 4 is composed of a CPU. The control processing unit 4 controls each component in the image measuring device 1 by executing various programs and performing necessary arithmetic operations to achieve image capture and image measurement performed by the image measuring device 1. The various programs include programs describing the functions of the image capture unit 3, the illumination unit 8, etc., and programs for image measurement applications that use images of the object to be measured (W) captured by the image capture unit 3 to perform measurements such as the dimensions of various components of the object W. The programs can be read from the storage unit 5 or from another storage medium.

[0027] Next, the measurement application software, one of the programs executed by the control processing unit 4, will be described.

[0028] Figure 4This diagram illustrates an example of a screen displayed on display unit 6 by the measurement application software. Camera view R1 is the area displaying the image captured by image capture unit 3. Toolbar R2 is the area displaying icons for frequently used functions in the measurement application software. When the operator taps an icon displayed on toolbar R2, the function corresponding to the tapped icon is executed. Option panel R3 is the area displaying various user interfaces required for measurement operations, including buttons such as confirmation button B1 and menu button B2, sliders, text boxes, toggle switches, etc.

[0029] Measurements using such measurement application software typically follow a series of steps: when the image captured by the image capture unit 3 is displayed in the camera view R1, the operator specifies the element or dimension of interest for the measurement, obtains the measurement value, sets the display mode or tolerance of the measurement value, and saves the measurement results that reflect these settings.

[0030] In this embodiment, the measurement application software displays a text notification indicating the next recommended action and a marker indicating the location of the action. Hereinafter, these text notifications and markers are referred to as recommended action notifications. The recommended action notification identifies the next recommended action based on the processing state of the measurement application software (e.g., the displayed image, the most recently performed action, the selection state of an element, etc.). The text notification and marker are then displayed according to the identified action. The next recommended action for each processing state is predetermined and described within the program of the measurement application software. These recommended action notifications enable the operator to understand the action they should perform next and the location of the user interface required to perform that action.

[0031] In this embodiment, the measurement application software provides two notification methods as notifications for recommended operations: "fixed location indication" and "operation location indication". Operators can choose how to receive notifications for recommended operations by configuring the measurement application software according to their preferences.

[0032] (Notification of recommended actions using fixed location indicators)

[0033] Figure 5 and Figure 6 An example is shown that uses a fixed position indicator to provide a notification recommending actions for a series of measurement operations. In the fixed position indicator, at a predetermined fixed position (at... Figure 5 and Figure 6 In the upper right of the camera view R1, a notification display area R4 for displaying text notifications is shown, along with a marker M indicating the location of a recommended action. The marker M can be displayed in a way that is easily visible to the user through color, brightness, flashing, movement, or other effects. For example, the marker M can be displayed in a highly visible color at (or near) the location of the recommended action.

[0034] The following is a specific example of the notification of recommended operations in the fixed position indication, along with a series of measurement operations. When the image of the measurement object W placed on the mounting table 2 is captured by the image capture unit 3, the captured image of the measurement object W is displayed in the camera view R1. In this state where only the image of the measurement object W is displayed, the next recommended operation to be performed is to extract elements (various geometric shapes contained within the shape of the measurement object W) from the image. Therefore, the measurement application software displays a notification stating "Please extract elements" in the notification display area R4, and displays a mark M ( ) superimposed on two icons IC related to the function of extracting elements on the toolbar R2. Figure 5 (S01 in the context). In this way, the operation location indicated by the marker in the notification of the recommended operation is not limited to one location, but can be multiple locations.

[0035] When the operator performs the element extraction operation, the shape of the extracted element is overlaid on the image of the measured object W in the camera view R1. With the element already extracted, the next recommended operation is to select the element of interest in the measurement. Therefore, the measurement application software displays a notification stating "Please select an element" in the notification display area R4, and displays a marker M overlaid on the shape representing the element displayed in the camera view R1. Figure 5 (S02 in the example). By analyzing the image of the object being measured, W, and extracting its elements, the positions of the elements on the image of the object being measured, W are identified. This allows the marker M to be superimposed on the positions of the elements on the image of the object being measured, as seen in the camera view R1. In other words, while the display position of the marker M changes based on the captured image of the object being measured, the marker can be displayed at a consistently appropriate position on the image, thus prompting the user to perform the next action.

[0036] Here, if multiple elements have been extracted, marker M can be displayed for all elements, or it can be displayed only for a limited number of elements (e.g., one). The element for which marker M is displayed can be determined based on predetermined conditions (e.g., the element closest to the image center, the largest element, etc.). Alternatively, marker M can be displayed at a location determined based on multiple elements (e.g., the centroid of multiple elements). The measurement application software can continue to issue... Figure 5 The notification of similar recommended operations in S02 continues until the required number and combination of elements for obtaining the measurement value (size value) are selected.

[0037] When the operator selects the desired number and combination of elements to obtain measurement values ​​by tapping the elements displayed in camera view R1, the measurement application software displays the measurement values ​​superimposed on the image of the object W to be measured in camera view R1, and displays dimension lines and dimension auxiliary lines as needed. Multiple measurement values ​​can be displayed depending on the number and combination of elements selected. Figure 5 In the example shown in S03, two parallel straight line elements are selected, and the distance between them is displayed as a measurement value. In this state, the next recommended action is to select the measurement value (dimensional value) to be recorded as the measurement result. Therefore, the measurement application software displays a notification stating "Please select a dimensional value" in the notification display area R4, and displays a marker M ( ) superimposed on the measurement value shown in the camera view R1. Figure 5 (S03 in the image). The position where the measured value is displayed within the camera view R1 varies depending on the selected element. However, since the measurement application software knows the display position of the measured value, the marker M can always be displayed in the appropriate position to prompt the user to perform the next operation. Here, when multiple measured values ​​are displayed, the operation position indicated by the marker M can be the display position of all measured values. Alternatively, the display position of a limited number (e.g., one) of the measured values ​​can be indicated. Which position among the display positions of the measured values ​​is used to display the marker M can be determined based on predetermined conditions (e.g., the display position of the measured value closest to the center of the image).

[0038] The operator selects a measurement value by tapping the value displayed in the camera view R1. With the measurement value selected in this way, the next recommended action is to confirm the element and measurement value (dimension value) to be recorded as the measurement result. Therefore, the measurement application software displays a notification stating "Please confirm the selected element and dimension" in the notification display area R4, and overlays the marker M on the confirmation button B1 displayed in the option panel R3. Figure 5 S04 in the middle).

[0039] By tapping the confirmation button B1, the operator confirms the element and measurement value (dimensional value) to be recorded as the measurement result. In this state, the next recommended operation is to edit the dimensional information of the measurement value, such as tolerances. Therefore, the measurement application software displays a notification stating "Please select and edit dimensional values" in the notification display area R4, and displays a marker M ( ) superimposed on the measurement value shown in the camera view R1. Figure 6 (S05 in the middle).

[0040] When the operator taps the measurement value displayed in the camera view R1, the measurement value is selected. In this state, the next recommended action is to select the content to be edited for the measurement value. Therefore, the measurement application software displays a notification stating "Please confirm the edit content" in the notification display area R4, and displays a marker M ( ) overlaid on the user interface for selecting the edit content displayed in the option panel R3. Figure 6 (S06 in the text). Figure 6 In the example, the marker M is overlaid on the toggle switch SW, which is used to select whether to enable editing content that sets the tolerance range to the measurement value.

[0041] When the operator taps the toggle switch SW to enable setting the tolerance range, the upper and lower limits of the tolerance range become editable. In this state, the recommended next step is to check the corresponding values ​​of the tolerance range and edit them as needed. Therefore, the measurement application software continues to display the notification "Please confirm edits" in the notification display area R4, while also displaying the mark M (overlaid on each value of the tolerance range shown in the option panel R3 and on the confirmation button B1.) Figure 6 (S07).

[0042] When the operator edits each value within the tolerance range as needed and taps the confirmation button B1, the tolerance range of the measured value is confirmed. In this state, the next recommended action is to save the measurement results or extract the elements again from the image to include the new measured values ​​in the results. Therefore, the measurement application software displays a notification stating "Please save or extract elements" in the notification display area R4, and overlays the mark M on the two icons IC related to the element extraction function displayed in the toolbar R2 and the menu button B2 at the top of the option panel R3. Figure 6 (S08 in the middle).

[0043] When the operator performs the element extraction operation, the shape of the extracted element is superimposed on the image of the measured object W in the camera view R1, resulting in a shape similar to... Figure 5 The state in S02 is then entered. Afterward, the operator continues the measurement operation until the measurements of all desired measurement points are included in the measurement results. During the operation, notifications of recommended actions similar to those described in S02 to S08 above are issued in response to the operator's actions. Alternatively, if the operator selects the save command from the displayed menu when pressing menu button B2, the measurement results are saved, and the series of measurement operations ends.

[0044] Based on the recommended operation notifications in the fixed-position instructions described above, operators can intuitively understand that they should perform the operation at the location indicated by marker M to execute the content notified in the notification display area R4. This allows even operators with limited knowledge of measurement operation methods to easily grasp the next operation to be performed. Therefore, measurement operations can be performed efficiently. Furthermore, by always displaying the notification display area R4 in the same location to inform the operator of the measurement operation overview, it provides the operator with a sense of security, allowing them to know the current task simply by looking at the fixed position.

[0045] (Notification of recommended actions using location indicators)

[0046] Figure 7 and Figure 8 An example is shown that uses an operation location indicator to provide a notification of recommended operations for a series of measurement operations. In the operation location indicator, a notification area R4 providing an overview of the measurement operations is displayed near the location of the recommended operation, along with a marker M indicating the location of the recommended operation.

[0047] The following is a specific example of the notification of recommended operations in the fixed position indication, along with a series of measurement operations. When the image of the measurement object W placed on the mounting table 2 is captured by the image capture unit 3, the captured image of the measurement object W is displayed in the camera view R1. In this state where only the image of the measurement object W is displayed, the next recommended operation to be performed is to extract elements (various geometric shapes contained within the shape of the measurement object W) from the image. Therefore, the measurement application software overlays the display mark M on two icons IC related to the function of extracting elements in the icons displayed on the toolbar R2, and places a notification display area R4 near these icons IC to display the notification "Please extract elements" (…). Figure 7 (Step S11). As shown in this example, when there are multiple locations for the recommended operation, the operation location indicated by marker M can be limited to one. In this example, marker M is displayed at the center position of the two icons IC related to the common function of the extracted element, and the notification display area R4 is placed near marker M. In this way, notifications can be provided near the location for the recommended operation while preventing the screen from becoming cluttered with numerous notification display areas R4.

[0048] When the operator performs the element extraction operation, the shape of the extracted element is overlaid on the image of the measured object W in the camera view R1. With the element already extracted, the next recommended operation is to select the element of interest in the measurement. Therefore, the measurement application software displays a marker M overlaid on the graphic representing the element displayed in the camera view R1, places a notification display area R4 nearby, and displays the notification "Please select an element" (…). Figure 7(S12 in the example). By analyzing the image of the object being measured, W, and extracting its elements, the positions of the elements on the image of the object being measured, W are identified. This allows the marker M to be superimposed on the positions of the elements on the image of the object being measured, as seen in the camera view R1, and the notification display area R4 to be superimposed nearby. That is, while the display positions of the marker M and the notification display area R4 change based on the captured image of the object being measured, the marker M and the notification display area can be displayed at a consistently appropriate position on the image, thus prompting the user to perform the next action.

[0049] Here, if multiple elements have already been extracted, the marker M can be displayed for all elements, or it can be displayed only for a limited number of elements (e.g., one). The measurement application software can then continue to send signals to... Figure 6 The notification of similar recommended operations in S12 continues until the required number and combination of elements for obtaining the measurement value (size value) are selected.

[0050] When the operator selects the desired number and combination of elements to obtain measurement values ​​by tapping the elements displayed in camera view R1, the measurement application software displays the measurement values ​​superimposed on the image of the object W to be measured in camera view R1, and displays dimension lines and dimension auxiliary lines as needed. Multiple measurement values ​​can be displayed depending on the number and combination of elements selected. Figure 7 In the example shown in S13, two parallel straight line elements are selected, and the distance between them is displayed as a measurement. In this state, the next recommended action is to select the measurement value (dimensional value) to be recorded as the measurement result. Therefore, the measurement application software displays a marker M overlaid on the measurement value shown in the camera view R1, and places the notification display area R4 nearby to display the notification "Please select dimensional value" (…). Figure 7 (S13). The position where the measured value is displayed within the camera view R1 varies depending on the selected element. However, since the measurement application software knows the display position of the measured value, it can always display a marker M or notification display area in the appropriate location to prompt the user to perform the next operation.

[0051] The operator selects a measurement value by tapping the measurement value displayed in the camera view R1. With the measurement value selected in this way, the next recommended action is to confirm the element and measurement value (dimension value) to be recorded as the measurement result. Therefore, the measurement application software will overlay the mark M on the confirmation button B1 shown in the option panel R3, and place a notification display area R4 nearby to display the notification "Please confirm the selected element and dimension" (…). Figure 7 (S14 in the text).

[0052] By tapping the confirmation button B1, the operator confirms the element and measurement value (dimensional value) to be recorded as the measurement result. In this state, the next recommended operation is to edit the dimensional information of the measurement value, such as tolerances. Therefore, the measurement application software displays a marker M overlaid on the measurement value shown in the camera view R1, and places a notification display area R4 nearby to display the notification "Please select and edit dimensional value" (…). Figure 8 (S15).

[0053] When the operator taps the measurement value displayed in the camera view R1, the measurement value is selected. In this state, the next recommended action is to select the content to edit for the measurement value. Therefore, the measurement application software displays a marker M overlaid on the user interface for selecting the edit content displayed in the option panel R3, and places a notification display area R4 nearby to display the notification "Please confirm the edit content" (…). Figure 8 (S16 in the text). Figure 8 In the example, the mark M is overlaid on the toggle switch SW, which is used to select whether to enable setting the tolerance range as the measurement value editing content, and a notification display area R4 is displayed near the location of the user interface for editing each value of the tolerance range.

[0054] When the operator taps the toggle switch SW to enable setting the tolerance range, the upper and lower limits of the tolerance range become editable. In this state, the recommended next step is to check the corresponding values ​​of the tolerance range and edit them as needed. Therefore, the measurement application software displays a mark M superimposed on each value of the tolerance range shown in the option panel R3 and on the confirmation button B1. Furthermore, a notification display area R4 is placed near each value of the tolerance range, and the notification "Please confirm the edits" continues to be displayed. Figure 8 (S17). As described, when multiple operation locations are indicated by the marker M, it is also possible to avoid placing the notification display area R4 near some operation locations.

[0055] When the operator edits each value within the tolerance range as needed and taps the confirmation button B1, the tolerance range of the measured value is confirmed. In this state, the next recommended action is to save the measurement results or extract elements from the image again to include the new measured values ​​in the results. Therefore, the measurement application software overlays the marker M on the two icon ICs associated with the function of extracting elements displayed on the toolbar R2, and on the menu button B2 at the top of the options panel R3. Then, the notification display area R4 is placed near the icon IC associated with the function of extracting elements, and displays the notification "Extract Elements". Another notification display area R4 is placed near the menu button B2 and displays the notification "Save". Figure 8 (S18 in the text).

[0056] When the operator performs the element extraction operation, the shape of the extracted element is superimposed on the image of the measured object W in the camera view R1, thus producing a state similar to S12. The operator then continues the measurement operation until the measurements of all desired measurement points are included in the measurement results. During the operation, notifications of recommended operations similar to those described in S12 to S18 are issued in response to the operator's actions. Alternatively, if the operator selects the save command from the displayed menu when pressing menu button B2, the measurement results are saved, and the series of measurement operations ends.

[0057] Based on the recommended operation notifications in the aforementioned operation location instructions, similar to those in fixed location instructions, the operator can intuitively understand that they should perform the operation at the location indicated by marker M to execute the content notified in the notification display area R4. This allows even operators with limited knowledge of measurement operation methods to easily grasp the next operation to be performed. Therefore, measurement operations can be performed efficiently. Furthermore, by focusing information near the area to be operated, eye movement can be minimized, thereby achieving efficient operation.

The above embodiments and variations are merely examples, and anything having a substantially identical configuration and producing the same effects as the technical concept described in the claims of this invention is included within the technical scope of this invention.
