For imageprocessing, the recognition of pointer instrument's reading by computervision highly depends on brightness. An image enhancement algorithm based on homomorphic filtering and histogram equalization is proposed in order to reduce the impact of low-light conditions on images of pointer instrument. It combines the methods of spatial with frequency domain, which enhances the image contrast and highlights the image details as well. Compared with the traditional method, the experiments show that the proposed method can eliminate the effect of inadequate light and also perform well in enhancing the image quality.

For the universality of computervision in the automatic detection of pointer instrument, an OpenCV-based automatic detection system for automobile meter was proposed and realized. The original video image was pre-processed through the filtering and SURF algorithm was used for the registration of template and test instruments to obtain the transformation parameters. Pointer and dial were treated respectively. Through the gray-scale images subtraction, Canny edge extraction and Hough line detection, the straight line where the pointer was obtained rapidly. Then the pointer readings were obtained through functional relation between the point angle and actual value. Experimental results show that this system can be used to conduct the real-time and automatic detection of different types of meters.
