摘要
介绍了一种以Freescale公司S12XS16位微控制器为核心控制单元,结合CMOS图像传感器的智能车系统的图像识别处理技术。该系统利用OV6620图像传感器获取图像信息,并通过一系列算法提取合适的轨迹参数,进而通过图像滤波整形、轨迹提取及PID模糊控制等优化算法对驱动电机和舵机进行精准的控制,从而使高速行进中的智能车具有良好的转向调节能力和快速加减速响应。
The image processing and recognition technologies which taking S12XS 16-bit microcontroller as key control unit,and combining CMOS image sensor with intelligent vehicle system were introduced,in which,having OV6620 image sensor employed to obtain image information,and to extract appropriate trajectory parameters through a series of algorithms;and basing on image filtering surgery,extraction trajectory and PID control algorithm,to have servo drive motor precisely controlled so that the intelligent car at high speed can have good turn regulation and quick acceleration/deceleration response.
