Recognition of Instrument Color Pointer Based on Color Extracting Method
Jiao Sheng-xi · Journal of Northeast Dianli University · 2012
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.
