摘要
主要论述了利用颜色提取及图像分割技术对汽车仪表指针位置进行识别处理的原理、步骤以及具体的实现过程。通过使用彩色提取和形态学图像处理技术,成功地提取了仪表盘中红色的指针,确定圆心并利用角度法计算出指针仪表读数。颜色提取方法为HIS颜色空间的坐标区域表示法,与常见的先把仪表图像转化成灰度图再进行处理的方法比较,此方法对于彩色指针仪表的识别更简单有效。
This thesis mostly discusses the image processing and recognition means of the dial pointer position using the technology of color extracting and image segmentation. The red pointer on the dashboard has extracted successfully and confirm the central point of automobile dashboard with the technology of color extracting and image segmentation. Then calculate pointer numerical using angle method. The method of color extracting is coordinate regional representation of color space, and the common method is doing image processing after turning instrument image into grayimage. For the recognition of color pointer, coordinate regional representation of color space is more effective.
