Research on Image Processing Technology for Dynamic Characteristics Test System of Electric Apparatus
摘要
Abstract
A fast image processing non-contact dynamic characteristic test system for electromagnetic apparatus is developed by means of high-speed camera and image processing technology in this paper. A series of images of contactor dynamic process can be acquired in this system. In order to reduce the noise effectively and improve the signal-to-noise ratio, the median filtering algorithm is applied to eliminate random noise and the image enhancement method is taken to highlight the image edges and details firstly. Then edge detection is undertaken by the Canny operators to get the edge images and the target can be found clearly by morphological transform, so that the target and data processing could be carried out. The results show that the data obtained by the method above are very close to the data obtained with Image-Pro Plus6. 0 software. In view of the electric signals of voltage and current combined with the motion signals of contactor and iron core obtained by the dynamic signal acquisition circuit, the complete dynamic characteristic curves with high real-time property can be obtained. It can provide the technical support for future research and design of electrical apparatus.关键词
