基于摄像头的路径信息采集系统的简易设计与实现

Simple Design and Implementation of camera based path Information Collection System

通过对智能车的研究发现,智能车跑道自身的颜色分别为白色和黑色两种,对图像颜色的明暗度并没有明确规定,因此,区分智能车的仅有条件则是反射光线的强度。因而,假如采用A/D实现采样,如此软件设计不但会变得较为复杂,而且获取不到理想的测量精度与响应时间,抗干扰的功能也会较低。此文章是利用了单片机传入获取的功能,在其单片机的内部安装了加强版定时器(ECT),它有一定的传入捕捉的能力,可以利用捕捉系统时钟脉冲对导引线进行测试。

Through the study of the intelligent car, the color of the intelligent runway is white and black, and the brightness of the image is not specified. Therefore, the only condition of distinguishing the intelligent vehicle is the intensity of the reflected light. So we use A/D to achieve sampling,in this way the software design will not only become more complex, and it could not get the ideal measurement accuracy and response time, the anti-jamming function will be lower. This article make use of the microcontroller to get access to the function, in its microcontroller installed within the enhanced version of the timer （ECT）, it has a certain ability to pass the capture, you can use the capture system clock pulse on the lead to test, the experimental results show that this method could not only improve the stability of the system performance, but it is also very easy to complete the operation.
