Reference).

The conventional image processing / inspection apparatus includes a camera 9
1 and two image data memories 92a and 92b for storing image data for one screen captured by the camera 91.

And a processing unit (not shown) that controls the control unit 3 to perform the measurement or inspection.

The processing section switches the selection switch circuit section 93, for example, with the camera 1 connected to the image data memory 92a, causes the camera 91 to take in image data for one screen, and stores it in the image data memory 92a. An image capturing process to be stored is executed. After completion of the image capturing process, the processing unit executes a measurement / inspection process for performing the measurement or the inspection based on the image data stored in the image data memory 92a. The next image capturing process is executed by using the image data memory 92b of FIG. As described above, the processing unit repeatedly and sequentially performs the image capturing process and the measurement inspection process.

The conventional image processing / inspection apparatus includes a monitor 94 and display image data memories 95a and 95b, and switches the monitor selection switch circuits 96a and 96b to display the camera 91 for display. The monitor 94 is connected via one of the image data memories 95a and 95.

[0006] As described above, the conventional image processing / inspection apparatus repeatedly performs image capturing processing and measurement / inspection processing in parallel and sequentially, and improves the performance of components such as ICs used in the processing unit and the like. Thus, various measurements or inspections such as the position and shape of the target object are performed in a short time.

[0007]

When the measurement or inspection of an object is actually performed using the above-mentioned conventional image processing and inspection apparatus in the production process of the object, in most cases, the image capturing processing is performed. This time is longer than the time required for the measurement / inspection processing being executed in parallel, and the processing time per unit (hereinafter referred to as “inspection tact”) in which the image capture processing and the measurement / inspection processing are sequentially and repeatedly executed in parallel. ")
Is substantially equal to the time required for the image capturing process.

However, the number of items of measurement or inspection of some objects may be larger than that of other objects depending on the state of the objects. At this time, measurement based on image data of the objects is performed. In the same manner as described above, the time required for the inspection process becomes longer, and when one image data captured from the camera includes a larger number of objects than other image data. However, the time required for the measurement inspection process based on the image data becomes longer. As a result, the time required for the measurement / inspection processing may be longer than the time required for the image capturing processing performed in parallel, once every several times.

In the above conventional example, if the time required for the measurement and inspection processing is longer than the time required for the image capturing processing as described above, there are only two image data memories.
For example, by executing an image capturing process, the image data memory 92a
After the image data is stored in the image data memory 92b
Is used to execute the next image capturing process, since the measurement and inspection process using the image data memory 92b is still performed, the next image capturing process cannot be performed immediately, and the measurement that took a long time There is a problem that the inspection tact becomes longer according to the time of the inspection processing, and the production processing capacity in the production process is reduced.

The above-described measurement inspection processing is executed based on the above, and during the execution of the measurement inspection processing, the next image capturing processing is executed using the other one of the image data memories 2a, 2b, and 2c. In this way, the processing unit 5 repeatedly performs the image capturing process and the measurement inspection process sequentially in parallel.

Further, the processing section 5 is provided for each image data memory 2
Management table 6 for grasping the states of a, 2b and 2c
The image capturing process and the measurement inspection process described above are sequentially and repeatedly performed based on the management table 6.

For example, as shown in FIG. 2, the management table 6 has first to third columns 6a, 6b, 6c in which the states of the respective image data memories 2a, 2b, 2c are individually written.

If "0" is written in c, the fields 6a, 6b,
"1" indicates that no image data is stored in the image data memories 2a, 2b, 2c corresponding to 6c.
Indicates that the image data is stored.

The processing section 5 sets "0" in the first column 6a and "0" in the second column 6b of the management table 6 shown in FIG.
Since "1" is written in the third column 6c, no image data is stored in the image data memories 2a and 2b, and the image data is stored only in the image data memory 2c. That the measurement inspection process has not been completed yet. Then, the processing unit 5 executes the image capturing process using the image data memory 2a, stores the image data in the image data memory 2a, and terminates the image capturing process, as shown in FIG. Thus, "1" is written in the first column 6a. Thereafter, when the measurement / inspection processing based on the image data stored in the image data memory 2c is completed, the processing unit 5
The image data stored in “c” is deleted, and “0” is written in the third column 6c as shown in FIG.

As described above, the processing unit 5 uses any one of the image data memories 2 by referring to the management table 6.

When the image capturing process is completed in No. 1, the first
"1" is written in the column 6a. Further, at this time, the processing unit 5 starts the measurement / inspection processing based on the image data stored in the image data memory 2a, and “0” is indicated in the second column 6b of the management table 6, After executing the image capturing process using the above-described image data memory 2a, the next image capturing process is continuously started using the image data memory 2b as shown in FIG.

Next, when the measurement / inspection processing based on the image data in the image data memory 2a shown in FIG. 3A is completed, the processing section 5 deletes the image data in the image data memory 2a and deletes the image data in the management table. "0" is written in the 1 column 6a. Thereafter, when the image capturing process using the image data memory 2b illustrated in FIG. 3B ends at time t2, the processing unit 5 writes “1” in the second column 6b of the management table.

Then, the processing unit 5 stores the third
Since "0" is shown in the column 6c of FIG.
As shown in (1), the next image capturing process is started continuously using the image data memory 2c, and the measurement / inspection process based on the image data in the image data memory 2b shown in FIG. 3B is started.

As described above, from time t1, the measurement and inspection processing and the image capturing processing are sequentially and sequentially repeated, and in most cases, the time required for the image capturing processing is longer than the time required for the measurement and inspection processing. Therefore, the processing time per unit (hereinafter, referred to as “inspection tact”) in which the image capturing process and the measurement inspection process are sequentially and repeatedly executed in parallel is substantially equal to the time required for the image capturing process.

3C, the time required for the measurement inspection process based on the image data stored in the image data memory 2b shown in FIG. 3B is reduced in parallel with the image data memory 2c shown in FIG. The processing unit 5 refers to the management table 6 even when the time taken for the image capturing process using the “?” Is longer and the measurement / inspection process is not completed even after the image capturing process is completed at time t3. Then, since “0” is indicated in the first column 6a, after the end of the image capturing process using the image data memory 2c described above (time t3),
The next image capturing process can be started continuously using the image data memory 2a shown in FIG.
