| 摘 要： | 利用HSI颜色空间中的色调提取方法,根据汽车仪表彩色指针的颜色特征提取出仪表的指针,为了消除仪表背景中与指针同颜色的像素,通过改进的差分算法提取出指针,确定指针圆心,并利用角度法计算仪表读数。研究中用MATLAB的GUI中ActiveX控件模拟了汽车转速仪表,将指针转动状态及角度判断实时显示在了模拟仪表中,实现了动态跟随。实验结果显示该研究方法对于彩色指针仪表的动态识别快速、便捷、有效。

Research on Automobile Dashboard Pointer Recognition Based on Color Extracting Method |
| |
| Abstract: | Hue extracting method of HIS color space is usd in this article,and the red pointer on the dashboard is extrcted by using automobile pointer color features.In order to eliminate those pixels which have the same color with the backgrounds of pointer,modified differencial algorithm is used,dashboard pointer is extracted,central point of the pointer is marked,and angle algorithm is used to calculate the pointer＇s reading.In the research work,ActiveX controls in the GUI of MATLAB is used to simulate car speed table,the pointer＇s rotation and angle are displayed in real-time,and dynamic tracing is realized. |
