In one embodiment, the first processing drawing and the first visual parameter of the product to be tested may be stored on a server, and the visual inspection apparatus performing the method of the embodiment is obtained from the server. The method for obtaining the first processing drawing and the first visual detection parameter of the product to be detected comprises the steps of obtaining product information of the product to be detected, and obtaining the first processing drawing and the first visual detection parameter of the product to be detected from a server according to the product information of the product to be detected.
In this embodiment, the user may set product information of the product to be tested for the visual inspection in the visual inspection device through a first configuration interface, where the first configuration interface may be as shown in fig. 2. The product information may be, for example, an item code for representing a product type of the product to be measured.
In the server, a second configuration interface can be provided, a user can set the second configuration interface, the user can configure product information of the product to be tested through the second configuration interface, and the first processing drawing and the first visual detection parameter of the product to be tested are uploaded through the second configuration interface so as to correlate the product information of the product to be tested with the first processing drawing and the first visual detection parameter of the product to be tested.
Further, the user can configure the association relationship among the work station, the working procedure and the product information through the server.
Specifically, the user can configure item codes, station codes, system line identification codes, line types, procedures, station codes and station names through the server. The basic information is the basis for realizing parameter uploading and parameter issuing acquisition.
In one example, as shown in fig. 3, the server may synchronize project information of the basic data platform, may input project codes or factory instance information that may synchronize the basic data platform unit with the station position, and may input inventory organization codes that may synchronize the project material number information of the basic data platform.
In one example, as shown in fig. 3, the server may further provide a quality parameter management list in the second configuration interface, where the quality parameter management list is displayed based on the item, unit, and test class, and only the latest version of the quality parameter is displayed. The server can also screen and display the items for users with different data authorities.

In one embodiment, the visual inspection apparatus for performing the method of the present embodiment may acquire the first processing drawing and the first visual parameter of the product to be tested from the server in the event of the parameter acquisition event. The event of acquiring the parameter may include receiving an operation of acquiring the parameter, and reaching a set update time.
In another embodiment, the visual inspection apparatus performing the method of the present embodiment may acquire the first processing drawing and the first visual parameter of the product to be tested from the server in the case that the operation of acquiring the parameter is received. The visual inspection device may be configured to obtain the first visual parameter of the product to be inspected from the server if the set update time is reached.

The first configuration interface may be as shown in fig. 2, and the first button may be a "pull parameter and save to local" button in the first configuration interface as shown in fig. 2.
In this embodiment, the user may set, in advance, a time interval for updating the visual parameter in the visual inspection process of the product to be inspected through the first configuration interface in the visual inspection apparatus, where the time interval may be, for example, 5 minutes.

That is, a second inspection program, which is being used by the visual inspection apparatus to perform visual inspection of the product to be inspected, is generated based on the second visual parameters.
Further, in the case that the second visual parameter is not stored in the visual inspection apparatus, the step of comparing the first visual inspection parameter with the second visual parameter of the product to be inspected may not be performed, and steps S1200 to S1400 may be continuously performed.
According to the embodiment, under the condition that the visual parameters are updated, the detection program used by the visual detection equipment can be updated in time, so that inaccurate visual detection results of the products to be detected caused by untimely updating of the detection program are avoided, and the qualification rate of the products to be detected is further influenced.
In one embodiment of the present disclosure, the method further includes the step of issuing an alarm when the first visual parameter is different from the second visual parameter, and executing a first inspection program that generates the product under inspection from the first machining drawing, the first visual inspection parameter, and the conversion parameter in response to a confirmation operation of the modification of the visual inspection parameter.
In this embodiment, when the first visual parameter is different from the second visual parameter, an alarm is sent, so that a tester can be reminded to confirm whether to test the product to be tested by using the first visual parameter. Under the condition that the tester confirms that the product to be tested is tested by using the first visual parameters, the tester can execute the confirmation operation of modifying the visual detection parameters, so that the visual detection equipment executes the subsequent steps S1200-S1400.
By the embodiment, the reliability and the accuracy of the visual detection result can be improved.
In one embodiment of the disclosure, the method further comprises visually inspecting the product under inspection according to a second inspection program when the first visual parameter is the same as the second visual parameter, wherein the second inspection program is an inspection program obtained according to the first processing drawing, the second visual inspection parameter and the conversion parameter.
In this embodiment, when the first visual parameter is the same as the second visual parameter, it indicates that the visual parameter of the product to be tested is not changed, and in order to reduce the computing power of the visual detection device, it may be unnecessary to generate the first detection program according to the first visual parameter to perform visual detection on the product to be tested. Thus, the second inspection program generated according to the second visual parameter can be used for continuously performing visual inspection on the product to be inspected.
By this embodiment, the computational effort of the visual inspection apparatus can be reduced.
Step S1200, obtaining a conversion parameter from the actual size of the product to be detected to the pixel size of the camera field of view.
In this embodiment, the camera may be calibrated according to the calibration product, to obtain a conversion parameter from the actual size of the product to be detected to the pixel size of the field of view of the camera.
In some embodiments, the camera may be recalibrated prior to visual inspection in the event that the visual inspection apparatus is replaced with a type of product that requires visual inspection.
In some embodiments, the conversion parameters may be stored in the visual inspection apparatus after calibration of the camera, and in the event that the inspection apparatus is not replaced with an inspected product type, the stored conversion parameters may be retrieved from the visual inspection apparatus if it is desired to generate an inspection program.
Step S1300, a first detection program of the product to be detected is generated according to the first processing drawing, the first visual detection parameters and the converted parameters.
The first detection program comprises at least one first detection frame of the product to be detected in the field of view of the camera.
In this embodiment, the first detection program may be configured to detect whether the deviation between the at least one to-be-detected area of the product to be detected and the corresponding first detection frame in the camera field of view corresponds to the corresponding first visual parameter.
In one embodiment of the disclosure, a first detection program of a product to be detected is generated according to a first processing drawing, a first visual detection parameter and a conversion parameter, and the first detection program is obtained according to the first processing drawing, a second detection frame represented by the actual size of the product to be detected is generated according to the first processing drawing, the second detection frame is processed according to the conversion parameter to obtain a first detection frame, and the first detection program is obtained according to the first detection frame and the first visual detection parameter.
In this embodiment, the second detection frame indicates the actual size of the product to be detected and the actual position of the area to be detected in the product to be detected.
Because the visual inspection is to shoot the product to be inspected by the camera, and whether the product to be inspected has defects is inspected according to the shot image to be inspected, the second inspection frame in the product to be inspected needs to be converted into the field of view of the camera according to the conversion parameters, so as to obtain the first inspection frame.
In one embodiment of the disclosure, the processing drawing is a 3D drawing, and generating a second detection frame represented by the actual size of the product to be detected according to the first processing drawing includes generating a 2D drawing of the product to be detected according to the 3D drawing, and analyzing the 2D drawing to obtain the second detection frame.
According to the embodiment, the detection program of the product to be detected can be automatically generated according to the 3D drawing, a tester is not required to manually draw the detection frame, the generation efficiency and accuracy of the detection program are improved, and the production efficiency of the product to be detected is further improved.
In step S1400, the product to be tested is visually inspected according to the first inspection program.
In this embodiment, the visual inspection of the product to be inspected according to the first inspection program may include controlling the camera to capture the product to be inspected to obtain an image to be inspected, and performing the visual inspection of the image to be inspected according to the first inspection program to obtain a visual inspection result of the product to be inspected.
