Abstract

The invention discloses an element recognition method. The method includes following steps: a to-be-matched target picture and at least two template pictures of a to-be-recognized element are read; template matching of the at least two template pictures and the to-be-matched target picture is performed, and at least two corresponding groups of matching values are obtained; operation of the at least two groups of matching values is performed according to a preset calculation rule, and a group of matching results are generated; and each matching result in the group of matching results is compared with a preset threshold, and the position of the to-be-recognized element on the target picture is recognized according to the relation of the matching results and the threshold. The invention also discloses an element recognition apparatus. According to the element recognition method and the apparatus, high recognition accuracy is guaranteed when the target picture is stained, incomplete, or deformed.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a component recognition method and device. Background technique [0002] In the field of image recognition, sometimes it is necessary to find a target of interest in a target picture containing many objects, for example, sometimes it is necessary to find a specified electronic component in a board picture containing many electronic components. [0003] The current solution is to directly use the template matching algorithm to perform template matching between the template image of the target of interest and the target image, and obtain the position of the target of interest according to the matching value obtained through the matching. However, when the graphics on the target image are defaced, missing or deformed, this method may have low matching efficiency and unstable matching values, which cannot meet the requirements of use. Contents of the invention [0004] In view of ...
