Abstract

The invention discloses a method for recognizing a component feature. The method comprises the following steps: acquiring a component picture to be recognized; marking the component picture as one having the component feature to be recognized; selecting a feature extraction algorithm with the highest recognition rate for the component feature from a database, wherein the database records the recognition rates of various feature extraction algorithms for the component feature; extracting an algorithm feature value of the component picture according to the feature extraction algorithm; recognizing whether the component picture has the component feature or not according to the algorithm feature value. Moreover, the invention further discloses a system for recognizing the component feature. Through the adoption of the method and the system provided by the invention, the feature extraction algorithm with the highest recognition rate for the component feature can be selected adaptively, so that effectiveness and accuracy are improved for recognition each time.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a component feature recognition method and system. 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] When the board is in a semi-finished state, it is necessary to detect each component on the board t...
