Abstract
En 中文
The use of computer vision to detect and recognize target objects in the industrial field has high academic value. In this paper, computer vision is used to identify cell's label and detect the surface scratch. Using inter variance threshold method of image acquisition threshold processing, to obtain a better image binarization, subsequent using characterization information to establish a template, and the template using mathematical morphology operations. Object matching is achieved by matrix change of the template, in order to achieve the detection. The experiments show that this method has higher accuracy and better real-time, so online detection can be used for battery characterization.
