Next, the functional configuration of the image processing device 1 will be explained.
FIG. 3 is a functional block diagram showing an example of the functional configuration of the image processing device 1 according to the first embodiment.
The functional configuration of FIG. 3 will be described below with reference to FIGS. 4 to 11.

The image processing device 1 includes a storage section 109, an image acquisition section 160, a measurement section 170, a composite image generation section 180, and an output section 190, as shown in FIG.

The storage unit 109 stores a first image of design information including at least a drawing and design dimensions of the article M. Here, an example of the design data PI corresponding to the first image in this embodiment is shown in FIG. Specifically, the storage unit 109 stores image data obtained by scanning a drawing or the like of the article M as design data PI. As shown in FIG. 4, the design data PI includes at least information such as a drawing, design dimensions, and tolerances of the article M. The storage unit 109 may store a plurality of design data PI.

The image acquisition unit 160 acquires a second image obtained by reading the article M. Here, an example of the imaging data MI corresponding to the second image in this embodiment is shown in FIG. Specifically, the image acquisition unit 160 acquires image data obtained by scanning the article M as the imaged data MI. For example, as shown in FIG. 5, the imaging data MI includes at least information such as an image of the article M to be measured.

The measuring unit 170 measures the dimensions of the article M based on the image data MI. Specifically, the measurement unit 170 measures the dimensions of each measurement target location of the article M by performing a predetermined image processing method on the image data MI acquired by the image acquisition unit 160. The measurement unit 170 then stores each measurement target location of the article M and the measurement results in association with each other. For example, as shown in FIG. 6, the measurement unit 170 may hold image data in which a result display area SW for displaying measurement results is displayed as imaged data MI.

The composite image generation unit 180 generates a third image in which a result display area SW in which the measured dimensions of the article M are displayed is superimposed on the design data PI. Here, an example of the composite image SI corresponding to the third image in this embodiment is shown in FIG.
The composite image generation unit 180 generates a composite image SI in which the result display area SW is superimposed on the design data PI by each unit that will be described below exerting its function.

Returning to FIG. 3, the explanation will be continued.
The composite image generating section 180 includes a specifying section 181 , a margin detecting section 182 , an overlapping area determining section 183 , a calculating section 184 , a format determining section 185 , and a recognizing section 186 .

The identifying unit 181 identifies design data PI corresponding to the article M to be measured from the design data PI stored in the storage unit 109. That is, the specifying unit 181 executes positioning processing based on the design data PI stored in the storage unit 109 and the image data MI acquired by the image acquisition unit 160, thereby matching the image data MI. Specify design data PI and imaging data MI.

Here, the alignment process will be described with reference to FIG. 7. FIG. 7 is a diagram illustrating a process of positioning the imaging data MI and the design data PI.

First, the specifying unit 181 analyzes the feature amount of each of the image N of the article M included in the imaging data MI and the drawing Z of the article M included in the design data PI. As a result, the specifying unit 181 extracts feature points SM-1 to SM-2 and feature points SP-1 to SP-2 as shown in FIG. 7, respectively. Then, the specifying unit 181 performs matching on the corresponding feature points (in the example of FIG. 7, feature point SM-1 and feature point SP-1, feature point SM-2 and feature point SP-2), and matches the image N with the drawing. Determine whether Z matches.
If the identification unit 181 determines that the image N and the drawing Z match as a result of such positioning processing, it determines that the design data PI including the drawing Z is the design data PI corresponding to the article M to be measured. Specify.

The recognition unit 186 recognizes design information based on the design data PI. Specifically, the recognition unit 186 recognizes the design information included in the design data PI by performing a predetermined image processing method on the design data PI identified by the identification unit 181. That is, for example, as shown in FIG. 8, the recognition unit 186 executes OCR processing to determine that the design dimension (reference value) and tolerance of the part A displayed in the design dimension display area PW-1 are 18±. 0.2, and that the design dimension (reference value) and tolerance of portion B displayed in the design dimension display area PW-2 are 1±0.2. Further, the recognition unit 186 recognizes the color, thickness, size, and other formats of characters such as the displayed design dimensions.
The recognition unit 186 stores the recognition results in association with each location in the drawing Z of the design data PI.

The calculation unit 184 calculates the dimensional difference between the design dimension and the measured dimension of each measurement target location of the article M. Specifically, the calculation unit 184 associates the design information recognized by the recognition unit 186 with the measurement result of the article M measured by the measurement unit 170, and calculates the dimensional difference.

The margin detection unit 182 detects a margin area in the design data PI where no information is displayed. Here, FIG. 9 shows an example of a blank area BP corresponding to a blank area in this embodiment. As shown in FIG. 9, the margin detection unit 182 executes a predetermined image processing method on the design data PI identified by the identification unit 181, and creates margin areas BP-1 to BP-3 in which no information is displayed. (hereinafter sometimes referred to as "margin area BP").

The superimposition area determination unit 183 determines a position in the margin area BP where the result display area SW for displaying the measurement results is superimposed. That is, the superimposition area determination unit 183 determines the position where the measurement result of the article M measured by the measurement unit 170 is to be displayed in the margin areas BP-1 to BP-3 in the design information PI of FIG.
Specifically, as shown in FIG. 10, for example, the superimposition region determining unit 183 sets a result display region SW-1 (hereinafter sometimes referred to as "result display region SW") that displays the measurement results of part A as It is decided to overlap a part of the margin area BP-1 extracted by the margin detection unit 182.
Further, for example, the superimposing region determining unit 183 determines to superimpose the result display region SW-2, which displays the measurement results of the part B, on a part of the blank area BP-2 extracted by the blank space detecting unit 182.

The format determining unit 185 causes the second format for displaying measured dimensions to follow the first format for displaying designed dimensions. Here, in the present embodiment, the format refers to a format that includes at least the font such as the color, thickness, and size of characters that display dimensions. That is, the second format for displaying measured dimensions is a format for displaying measurement results, and the first format for displaying design dimensions is a format for displaying design dimensions.
Specifically, as shown in FIG. 10, the format determining unit 185 converts the format of the measurement results displayed in the result display areas SW-1 to SW-2 into the format recognized by the recognition unit 186 (the example shown in FIG. 10). Then, control is performed to match the font of the design dimensions and tolerances displayed in the design dimension display areas PW-1 to PW-2.

Further, based on the result calculated by the calculation unit 184, if the dimensional difference between the design dimension and the measured dimension is larger than a predetermined threshold, the format determination unit 185 converts the measured dimension into the format indicated by the design information. controls to display in a different third format. Specifically, if the dimensional difference between the design dimension and the measured dimension is larger than the tolerance as the threshold value, the format determination unit 185 changes the measured dimension displayed in the result display area SW-1 to the designed dimension. The design information is controlled to be displayed in a format different from that displayed in the display area PW-1. For example, in the example of FIG. 11, the design dimension and tolerance displayed in the design dimension display area PW-1 corresponding to part A are 18±0.2, while the measurement displayed in the result display area SW-1 The result is 18.5. That is, since the dimensional difference between the design dimension and the measured dimension is larger than the tolerance of 0.2, the format determining unit 185 displays the measurement result displayed in the result display area SW-1 in bold and large font. Control as follows.

The functions of each section included in the composite image generation section 180 have been described above. In this way, each part of the composite image generation unit 180 performs its function, thereby generating a composite image SI in which the result display area SW is superimposed on the design data PI.

The output unit 190 outputs the composite image SI as the third image. That is, the output unit 190 executes control to output the composite image SI generated by the composite image generation unit 180 to the operation panel 140 or the like.

Next, the flow of work when performing such image composition processing will be explained. FIG. 12 is a schematic diagram showing the flow of operations of the worker W and the image processing device 1 when the image synthesis process according to the first embodiment is executed.

The worker W places the design information of the article M on the contact glass 11 of the image processing device 1 (step S111). Specifically, for example, the worker W places a medium such as a drawing on which the design information of the article M is fixed on the contact glass 11. The worker W operates the operation panel 140 of the image processing device 1 and instructs to start scanning (step S112).

The image processing device 1 starts scanning (step S113). Specifically, scanning of design information is started when the carriage 12 of the image processing device 1 moves.

The image processing device 1 stores the scanned design data PI in the storage unit 109 (step S114). Specifically, the storage unit 109 stores design data PI obtained as a result of scanning the design information of the article M.

The worker W removes the medium from above the contact glass 11 of the image processing apparatus 1, and places the article M to be measured on the contact glass 11 instead (step S115).

The worker W operates the operation panel 140 to specify the measurement site of the article M (step S116). Then, the worker W operates the operation panel 140 and instructs to start measuring the dimensions of the article M (step S117).

The image processing device 1 starts scanning the article M (step S118). That is, the image acquisition unit 160 of the image processing device 1 acquires the image data MI obtained as a result of scanning the article M.

The image processing device 1 measures the dimensions of the article M (step S119). That is, the measurement unit 170 of the image processing device 1 measures the dimensions of the measurement target portion of the article M by performing a predetermined image processing method on the image data MI acquired by the image acquisition unit 160. The measurement unit 170 stores each measurement target location and the measurement result in association with each other.

Next, the image processing device 1 starts processing for outputting a combination of the stored design data PI and the measurement results of the article M (step S120). Such processing in step S120 is particularly referred to as "image generation processing."
Next, details of the image generation process will be explained with reference to FIG. 13.
FIG. 13 is a flowchart illustrating an example of image generation processing according to the first embodiment.

The specifying unit 181 reads the design data PI stored in step S114 (step S201).

The specifying unit 181 executes alignment processing (step S202). Thereby, the design data PI corresponding to the article M to be measured is specified, and the blank area BP for superimposing the result display area SW in the design data PI can be detected.

The margin detection unit 182 detects the margin area BP based on the extracted design data PI. Specifically, the margin detection unit 182 extracts a margin area BP in which no information is displayed from the design data PI (step S203).

The calculation unit 184 performs calculations such as determining the dimensional difference between the design dimension and the measured dimension of each measurement target location of the article M, and determining the measurement result based on the calculated dimensional difference (step S204). This allows the difference between the design dimension and the measured dimension to be automatically calculated, making it easier to recognize the result.

The format determining unit 185 determines the format of the measurement results to be displayed in the result display area SW (step S205). That is, the format determining unit 185 determines the format of the measurement results displayed in the result display area SW to follow the format indicating the design dimensions, or to an arbitrary format.

The superimposition area determining unit 183 determines a position in the extracted blank area BP at which the result display area SW is to be superimposed (step S206).

As described above, the image generation process in step S120 ends. In this manner, each part of the composite image generation unit 180 functions to generate a composite image SI in which the result display area SW, in which the measured dimensions of the article M are displayed, is superimposed on the design data PI. .
Returning to FIG. 12, the process proceeds from step S120 in FIG. 12 to step S121.

The output unit 190 executes control to output the composite image SI. Specifically, the output unit 190 executes control to output a composite image SI in which the measurement results of the dimensions of the article M are superimposed on the design data PI to the operation panel 140, a paper medium, or as electronic data (step S121).

In this way, the worker W obtains the composite image SI as an output result, and ends the work (step S122).
The flow of operations of the worker W and the image processing device 1 when the image composition process according to the first embodiment is executed has been described above.

In this way, the image processing device 1 according to the first embodiment calculates the dimensions of the article M by combining the design data PI in which the design information of the article M is read and the image data MI obtained by reading the article M. A new composite image SI in which the measurement results are superimposed on the design data PI can be output. As a result, the measurement results and the design information can be displayed and output side by side, making the results easier to see and making it possible to understand at a glance whether the measurement results match the design information. Therefore, according to this embodiment, it is possible to improve the efficiency of the work performed by the operator.

Furthermore, the image processing device 1 according to the first embodiment can superimpose a result display area SW that displays the measurement results of the dimensions of the article M on a blank area BP in which no information of the design data PI is displayed. . Thereby, it is possible to avoid overlapping the design dimension display area P and the result display area SW. In addition, since the overlapping location of the result display area SW is automatically determined without manual adjustment by the operator, work efficiency is improved and, for example, the position of the result display area SW with respect to the design dimension display area PW is determined automatically. Relationships can be maintained constant.

Furthermore, the image processing device 1 according to the first embodiment can match the format for displaying measurement results with the format of design information. Therefore, the measurement results and design information can be displayed and output side by side in the same format without manual settings by the operator, making it possible to easily confirm the measurement results.

Furthermore, the image processing device 1 according to the first embodiment calculates the dimensional difference between the design dimension and the measurement result, and determines the measurement result with respect to the design tolerance, for example, if the dimensional difference is larger than a predetermined threshold, etc. In this case, the measurement results are displayed in a predetermined format. This makes it possible to highlight and display only the results in which the measurement results deviate from the threshold, so that it is possible to easily recognize at a glance whether the results are acceptable or not.

(Modified example of the first embodiment)
In the above-described embodiment, the storage unit 109 is described as being located in the image processing device 1, but the storage unit 109 is not limited thereto. For example, the storage unit 109 may be a predetermined storage medium such as a USB memory, or an external server. The image processing device 1 may generate the composite image SI based on the design data PI stored in such a storage medium or server.

In the above-described embodiment, it has been explained that the storage unit 109 stores image data obtained by scanning the design drawing of the article M, etc. as the design data PI, but the invention is not limited to this. For example, the storage unit 109 may store separately prepared image data as the design data PI.

In the embodiment described above, the design information such as the design dimensions and tolerances of the article M is described as being automatically recognized by the recognition unit 186, but the recognition method is not limited to this method and may be any arbitrary method. For example, an operator may manually input the design information via the operation panel 140.

Furthermore, in the above-described embodiment, the position at which the result display area SW is superimposed has been described as being automatically determined by the superimposition area determining unit 183, but the method for determining the superimposition position is not limited to this, and may be determined arbitrarily. good. For example, the operator may manually specify the position where the result display area SW is to be superimposed via the operation panel 140.

(Second embodiment)
In the first embodiment, the method of generating the composite image SI in which the measurement results of the dimensions of the article M are superimposed on the design data PI has been described, but in the second embodiment, the design information of the article is superimposed on the imaging data MI. A new composite image SI superimposed on the image is output.
In the second embodiment, a process for generating such a composite image SI will be described.
Note that descriptions of parts common to the above-described first embodiment will be omitted as appropriate. The external configuration, hardware configuration, and functional configuration of the image forming apparatus according to the second embodiment are the same as those of the first embodiment.

FIG. 14 is a schematic diagram showing the flow of operations of the worker W and the image processing device 1 when the image synthesis process according to the second embodiment is executed.

Note that steps 131 to 139 in FIG. 14 are the same as steps 111 to 119 described in FIG. 12 in the first embodiment, so the process first proceeds to FIG. 15 and mainly describes the image synthesis process in step S140. .

Referring to FIG. 15, the image generation process in step S140 in FIG. 14 will be described.
FIG. 15 is a flowchart illustrating an example of image generation processing according to the second embodiment.

The specifying unit 181 reads the design data PI stored in step S114 (step S401).

The specifying unit 181 executes alignment processing (step S402).

The recognition unit 186 recognizes design information such as design dimensions and tolerances included in the design data PI. (Step S403).

The calculation unit 184 performs calculations such as determining the dimensional difference between the design dimension and the measured dimension of each measurement target location of the article M, and determining a result based on the calculated dimensional difference. Then, the format determining unit 185 determines the format of the design dimensions to be displayed in the design dimension display area PW based on such calculation results (step S404).

The superimposition region determination unit 183 determines a position in the image data MI at which the design dimension display region PW is to be superimposed (step S405). That is, the superimposition region determination unit 183 can superimpose the design dimension display region PW on any position of the image data MI.

As described above, the image generation process in step S140 ends. As described above, each part of the composite image generation section 180 functions to generate a fourth image in which the design dimension display area PW in which the design dimensions are displayed is superimposed on the imaging data MI. Here, an example of the composite image SI corresponding to the fourth image in this embodiment is shown in FIG. 16.
As shown in FIG. 16, in the imaging data MI, the composite image generation unit 180 creates a design dimension display area PW-1 in the vicinity of the result display area SW-1 that displays the measurement results of the part A, and a design dimension display area PW-1 of the part C. A composite image SI is generated in which the design dimension display area PW-2 is superimposed in the vicinity of the result display area SW-2 that displays the measurement results.
Returning to FIG. 14, the process proceeds from step S140 in FIG. 14 to step S141.
