[0002] In the current factory-produced equipment, the specifications of the parts used in each device must be accurate. If there is a mistake in the installation of parts, it will inevitably lead to customer complaints. For example, in the current vehicle production process, there are cases where export vehicles are produced. The parts standards of export vehicles are different from domestic standards, so there will inevitably be differences in parts specifications. According to the inspection requirements before export mass-produced vehicles leave the factory, the parts label specifications of export mass-produced vehicles are inspected to avoid export mass-produced vehicles affecting customer satisfaction due to the wrong installation of parts of domestic version specifications.

[0052] See also Figure 3 The staff can fix the head-mounted wireless camera 100 through the AR glasses, and can observe in real time through the AR glasses whether there are any installation errors in the parts during the verification process.

[0053] It should be noted that the display device 300 is a screen projection device;

[0054] The screen projection device projects the comparison result to a target area.

[0055] The detection mechanism of the component label specification inspection device is:

[0056] 1. Read the pictures collected by the head-mounted wireless camera 100 in real time and convert them into grayscale images;

[0057] 2. Perform noise reduction filtering on the image and increase contrast processing;

[0058] 3. Perform shape-based template matching. First, read the preset template contour, and compare the template contour from left to right and from top to bottom in the detection area. When the similarity reaches the set threshold, it is determined to be a match. That is, the corresponding component label contour is detected.

[0059] 4. Through affine transformation and projection transformation, the template contour is reflected on the captured image.

[0060] 5. Finally, save the result image and data.

[0061] During the inspection process, when the inspector moves, the collected image state becomes unstable and the captured component labels have a certain degree of perspective deformation. The uncalibrated perspective deformation template matching operator is used to match and detect the deformed contours.

[0062] It can be understood that the technical solution shown in this embodiment can ensure the reliability of automatic detection and judgment of the visual inspection system for the label specifications of export vehicle parts, formulate multiple test measures for malicious verification, and grasp the reliability of equipment detection;

[0063] Among them, malicious testing is carried out to verify the defective detection rate of parts labels (such as wrong specifications, scratches, stains, and damage). By verifying the equipment and confirming the verification test, it can be verified that under extreme circumstances, there will be no abnormal outflow in the visual inspection system of parts labels of exported vehicles. When the equipment finds that the specifications of parts labels are incorrect, the AR glasses display screen automatically displays a failing interface and sends out an alarm sound of a bad signal. The inspector records the abnormal problem on the vehicle performance registration form and sends the vehicle to the repair area for repair and reconfirmation of the problem before proceeding to the next process inspection.

[0064] In addition, in order to ensure the stability of equipment, a routine status inspection benchmark table is established. Inspectors conduct routine status inspections on all production vehicles every day (including routine status inspections and technical inspections of new models). Two vehicles are randomly selected for equipment status confirmation to ensure the accuracy and stability of equipment inspections.
