Description

technical field [0001] The invention mainly relates to the technical field of product machine vision quality inspection and control on an automated production line, in particular to a high-speed real-time image processing method and a detection system applied to multi-station machine vision quality inspection on a high-speed automated production line. Background technique [0002] At present, on a high-speed automated production line, it is usually necessary to perform multi-station quality inspection on a certain product. Multi-station quality inspection can detect more parameters, such as detection of different types of foreign objects at different stations in liquid product quality inspection, liquid level inspection, appearance quality inspection, etc.; at the same time, multi-station inspection can improve The accuracy of quality inspection, such as multiple inspections of inspection objects at multiple stations can improve the accuracy of inspection of unqualified prod...

AI Technical Summary

Problems solved by technology

[0005] 1. Complicated and large-scale machine vision equipment

Multiple stations require multiple computers, which increases the volume and cost of machine vision inspection equipment;

[0006] 2. It is difficult to synchronize the detection of multiple stations

Since each computer works independently, the detection system needs to synchronize multiple detection processes. Since the detection time of a single computer is difficult to control, the current system structure increases the difficulty of real-time synchronization of each station, and it is difficult to realize the stability of multiple stations for the same product. Reliable detection;

[0007] 3. It is difficult to realize the coordinated control of the whole machine

[0008] Due to the above problems, most of the current high-speed automated production line machine vision inspection equipment is limited to the detection of a single station; the multi-station inspection system is extremely complex and has poor stability; the multi-station machine vision quality inspection system is still one of the current machine vision inspection equipment. unresolved technical problems
