| 摘 要： | 该方法先用Hough变换进行初始化的仪表指针中心点检测，然后将指针图像向中心点进行投影来搜索检测指针位置。实验结果表明：该方法能较准确地指针检测识别精度，同时与传统的Hough变换相比，运算速度能提高3～4倍左右，并可以大大减少存储空间。

| Abstract: | The Hough transform is firstly used to detect the center point of the dial. The dail image is then projected to the center point and the dial indicator is finally detected from the image center-point-based projection. Experiments show that the proposed method works very well for the dial indicator detection. Comparing with the classical Hough transform, it has the merit of fast processing speed and very low computation storage. |
