Reference numeral 2 denotes an image memory for storing image data obtained from the A / D converter 101; 103, an image processing LSI functioning as a peripheral circuit for image processing; 104, a D for digital / analog conversion of a digital image signal. / A converter,
105 is mainly composed of a microprocessor,
A CPU for overall control of the entire apparatus, a data memory 106 for storing various setting data necessary for measurement and inspection, and a console interface (I / F) 107 to which a console for giving various operation commands is connected ), 1
Reference numeral 08 denotes a serial input / output interface (I / F) for transmitting / receiving serial data to / from an external device, and reference numeral 109 denotes a parallel input / output interface (I / F) for transmitting / receiving parallel data to / from an external device.

The operation of the apparatus will be described systematically and simply.
For example, a product to be inspected (not shown) on a transport line is
Image data is taken by the inspection camera 120 and image data obtained by this is sequentially stored in the image memory 102.
The CPU 105 performs various image processings on the image data stored in the image memory 102 in accordance with various setting data set by the user, performs measurement of the product, determines acceptability, and the like, and performs measurement as a result of the measurement. Numerical data and binary signals as judgment results are serially input / output 108
And to the parallel input / output 109 to send to an external device (for example, a PLC or a personal computer). At the same time, these measurement results and determination results are also displayed on the screen of the image monitor 130, for example, “100.52 mm”, “OK”, “NG”.
And so on.

The setting data set by the user for image processing includes, for example, area specifying data for specifying an inspection target area, reference pattern data for specifying a pattern to be inspected, and pass / fail of the inspection target. There are various patterns such as a threshold pattern for judging.

For this reason, the internal R
In the OM (not shown), a processing program in a measurement mode for executing measurement on an object based on input image data and a processing program in a setting mode for executing settings required for measurement on the object are alternatively provided. Is built into the executable.

[0006]

In an inspection using this kind of visual inspection apparatus, in order to obtain accurate measurement values and inspection results, various setting data values necessary for the measurement and inspection are also required. It must be as accurate as possible. Therefore, in this type of visual inspection, it is necessary to readjust the value of the setting data according to the value of the measurement result or the inspection result.

In order to readjust the setting data, the operation mode must be switched from "measurement mode" to "setting mode". As described above, the internal ROM (not shown) included in the CPU 105 stores the processing program in the measurement mode for executing the measurement on the object based on the input image data and the settings required for the measurement on the object. A processing program of a setting mode to be executed is installed so as to be alternatively executable.

For this reason, if the operation mode is switched from the “measurement mode” to the “setting mode” and the setting data is readjusted, the visual inspection cannot be executed during that time. Alternatively, in order to avoid the occurrence of defective products, the production line must be temporarily stopped during that time.

In order to enable the execution of the "measurement mode" even during the execution of the "setting mode", a product having a high operating speed is adopted as a microprocessor constituting the CPU 105, and a so-called time slice process is performed. It is conceivable to execute the operation program in the “setting mode” and the operation program in the “measurement mode” simultaneously and in parallel.

Incidentally, an image processing LSI 103 functioning as a peripheral circuit for image processing is incorporated in an image processing section of this type of visual inspection apparatus, and this image processing LSI 103 gives one image processing command. It takes a certain amount of time for the results to appear.
In addition, when performing a test measurement operation in the “setting mode”, it is necessary to operate the image processing LSI 103 in the same manner as in the “measurement mode”.

[0011] Therefore, if only the speeding up of the processor is performed,
It is extremely difficult to execute the “setting mode” operation program and the “measurement mode” operation program simultaneously and at high speed.

On the other hand, on the intermediate system side, the console request processing (corresponding to the received command) (step 511), the first image processing system corresponding processing (step 512), and the second image processing system corresponding processing (step 512) 513) is repeatedly executed. The details of each of these processes will be described in more detail with reference to the drawings in FIG.

FIG. 6 is a flowchart showing details of the received command handling process. When the process is started in the figure, the system enters a state of waiting for reception of a command from the intermediate system (step 601). Here, when any command is received from the intermediate system 270 (step 601 YES), the command is decoded according to a normal procedure (step 602), and various processes are executed according to the decoding result.

That is, if it is determined that the command is a setting data transmission request command as a result of decoding the command (YES in step 603), the requested setting data is read from the data memory and sent to the intermediate system 270. Is transmitted (step 604). That is, as will be described later in detail, when an instruction to transfer data from the first image processing system to the second image processing system is given from the outside via the console 240, the intermediate system 270 side , Sends a transfer request command to the first image processing system 250 regarding the corresponding setting data. Then, in step 603, it is determined that there is a setting data transmission request (step 603YE).
S), the setting data requested as a result is stored in the intermediate system 2
It is transmitted to the side of the server 70 (step 604).

On the other hand, as a result of decoding the command (step 602), when it is determined that the command is a setting data reception request command (step 605YE).
S), the setting data requested to be received is transferred to the intermediate system 270
Is executed (step 60).
6). That is, as will be described later in detail, in the system of the present invention, when a setting data transfer command is externally given from the second image processing system to the first image processing system, the intermediate system 270 sends the first image processing system A setting data reception request command is issued to 250. Then, it is determined that there is a setting data reception request (step 605 YES), and the requested setting data is received from the intermediate system 270 (step 606).

On the other hand, as a result of decoding the command (step 602), when it is determined that the content is a mode change request command (step 607), an operation mode change process is subsequently executed (step 608). ). That is, as will be described in detail later, in the system of the present invention, an operation mode change request from the outside via the console 240 (for example, an operation mode change command from the measurement mode to the setting mode for the first image processing system) Is given, the intermediate system 270 issues a mode change request command to the first image processing system 250. Then, it is determined that there is a mode change request command (step 607 YES), and the operation mode change processing (step 60) is performed on the first image processing system 250 side.

04), setting data reception processing (step 606) and operation mode change processing (step 608) are performed. In particular, in the operation mode change processing (step 608), the contents of the operation mode flag (not shown) stored in the first image processing system 250 are automatically changed to the contents specified by the command. .

FIG. 7 is a flowchart showing details of the operation mode execution processing. When the process is started in the figure, a reading process of the operation mode is performed (step 701), and then a determination is made as to whether the mode is the measurement mode or the setting mode based on the read content (step 7).
02, 704).

If the determination of the measurement mode is made (YES in step 702), a predetermined measurement program is executed (step 703). As is well known, in the execution of the measurement program, the CPU 2 compares the image data stored in the image memory 251 with the CPU 2.
By giving a designated command from the 53 to the image processing LSI 252, various types of image processing are executed in accordance with the contents of the setting data stored in the memory 254.
As described above, the content of this image processing is to read a specified pattern from the specified area of the image data and measure it according to a predetermined measurement algorithm, or execute pattern recognition and pattern matching, etc. As a result, the presence / absence of the specific pattern and the number of the specific patterns are measured, and the quality of the product is determined by comparing the measured value with a reference value.

On the other hand, if the operation mode is determined to be the setting mode (step 704 YES), a known setting program is executed (step 705). As is well known, in the setting program (step 705), various setting data is input while interacting with the user using the screen of the image monitor 230. As is clear from the above description of the flowchart, these two programs (measurement program and setting program) are executed alternately, and are not processed simultaneously by time slice. is not.

FIG. 8 is a flowchart showing details of the command request processing. When the process is started in the figure, the system enters a state of waiting for a command from the console 240 (step 801). In this state, when any command is received from the console 240 (step 801), the command is decoded (step 802), and the command is decoded (step 80).
3A, 803B, 803C), three processes (804, 8
05,806) are executed alternatively.

That is, when it is determined that the content of the command received from the console is a mode switching command (step 803A), processing for transmitting a mode change request command to the designated system is executed. (Step 804). That is, for example, if the command is to switch the operation mode of the first image processing system 250 from the measurement mode to the setting mode, the intermediate system 27
From 0, a command to switch the operation mode from the measurement mode to the setting mode is transmitted to the first image processing system 250.

If the decrypted content is (step 80)
3) If it is determined that the command is a setting data transfer command (step 803B), a process of transmitting a transfer data transmission request command to the transfer source system is executed (step 805). For example, if the content of the setting data transfer command is
If the command is to transfer the contents of the setting data stored in the memory 254 (for example, some setting has already been changed) from the first image processing system 250 to the second image processing system 260, the intermediate system 270 To the first image processing system 250, a command to transmit the changed setting data stored in the memory 254 to the intermediate system 270 is sent. Conversely, if the externally supplied setting data transfer command is to transfer setting data from the second image processing system 260 to the first image processing system 250, the intermediate system 27
0 to the second image processing system 260
A command to transmit the setting data stored in the memory 64 is issued.

Finally, the decrypted contents are displayed (step 80).
2) If it is determined that the command is a run / stop command (step 803C), a process of transmitting a run / stop request command to the designated system is executed (step 8).
06). That is, for example, when a command to stop the first image processing system 250 arrives from the console, the intermediate system 270 transmits a stop request command to the first image processing system.

Next, FIG. 9 is a flowchart showing details of the processing corresponding to the first and second image processing systems.
FIG. 7A is a flowchart showing details of the first image processing system compatible processing, and FIG. 7B is a flowchart showing details of the second image processing system compatible processing.

Since these processes are the same for the first image processing and the second image processing, only the first image processing system will be described below, and the second image processing system will not be described. Description is omitted.

When the process is started in FIG.
The system is in a state of waiting for reception of setting data from the first image processing system (step 901). In this state, the first
When the reception of the setting data from the image processing system is confirmed (YES in step 901), the received data is stored in the data memory 272 incorporated in the intermediate system 270 (step 902). Then, a setting data reception request command is transmitted (step 903).

Thereafter, if the second image processing system 260 responds that the reception is OK (step 904YE).
S), a process of transmitting the received data to the second image processing system 260 is executed (Step 905).

Such processing (steps 901 to 90)
As a result of the execution of 5), the setting data can be transferred from the first image processing system 250 to the second image processing system 260 via the intermediate system 270. At that time, an intermediate system 270 exists between the first image processing system 250 and the second image processing system 260,
Further, since there are system interfaces 276 and 277 that alternately gate on between the intermediate system 270 and each image processing system, the first image processing system 250 and the second image processing There is no need for the CPU to cooperate with the system 260, so that the respective systems 250 and 260 can continue control operations without any interruption.

FIG. 10 is a flowchart showing the procedure for transferring the setting data. In this example, first, in the normal state, measurement is performed on the first system side (step 1001). After that, the measurement is switched to the measurement in the second system (step 1002), and the setting contents of the first system are updated (step 100).
3). The update of the setting content is performed by changing the setting on the console of the intermediate system. Next, the setting contents of the first system are transferred to the intermediate system (step 1004), and the measurement is switched to the measurement in the first system (step 1005). Thereafter, the settings are transferred from the intermediate system to the second system (step 10).
06).

As described above, although the measurement was initially performed in the first system, the measurement was switched to the measurement in the second system, and the contents of the setting data empirically obtained in the first system are changed to the second system. Transferred to system side. As a result, according to this embodiment, the setting data can be readjusted while the product inspection is continued, and the measurement processing or calculation can always be performed with the optimal setting data. In particular, since there is no need to stop the measurement processing or the inspection processing, there is no need to stop or stop the production line, and the usability is significantly improved as compared with the conventional system.
