Description
technical field [0001] The invention relates to the field of automatic optical inspection, in particular to an automatic light source adjustment method. Background technique [0002] Automated Optical Inspection (AOI, Automated Optical Inspection) is an effective inspection method for industrial automation. Machine vision is used as the inspection standard technology. It is widely used in LCD / TFT, transistor and PCB industrial processes, and it can be extended to security systems for people's livelihood. . Automatic optical inspection is a common representative method in industrial manufacturing processes. It uses optical methods to obtain the surface state of finished products, and uses image processing to detect defects such as foreign objects or abnormal patterns. Because it is a non-contact inspection, semi-finished products can be inspected in the middle of the process. [0003] In the circuit board production process, it is necessary to identify the type of each board...
