摘要
在全国大学生智能车比赛中,控制车模运行需要检测赛道参数.该文提出了一种使用CMOS摄像头进行赛道参数检测的方法.该方法充分利用了MC9S12DG128单片机内部硬件资源,配合硬件二值化电路,采集CMOS摄像头输出的模拟信号.获得满足参数检测需要的信息后,可以计算出赛道参数.实验证明,该方法简便、有效.
In the National University Intelligent Automotive Competition, it was required to detect the racetrack parameters to control the model car. Thus we employed a CMOS camera to complete the detection. The method made full use of the internal hardware resources of MCU MC9S12DG128 chip to collect the analog output signal from CMOS camera, with the aid of hardware binary circuit. The racetrack parameters could then be evaluated after the information needed for parametric detection was obtained. Experiments showed that the method is simple and effective.
