Abstract

Because of the good antinoise performance and non-sensitive traits against the partly covers phenomenon, the Hough transformation has been widely used in the fields of machine vision and pattern recognition. The automatic recognition of pointer instrument always uses digital image processing methods. In order to obtain accurate indication, this paper utilizes some edge detecting methods to obtain the binary image of instrument dials and pointer feature. Based on the Hough transform, this paper describes the application of automatic recognition of traditional instrument pointer which has been proved to be effective on improvement of computing efficiency. And it makes possible to detect pointer instrumentation real-time and low-cost.
