基于视频的自动巡航智能小车的设计与实现

为了进一步提高自动巡航智能小车的速度，在图像采集部分，将模拟CCD摄像头架高并减小其俯角，并在单片机外部搭建高速AD转换电路。在驱动部分，用H桥驱动电路正反向驱动智能小车前进和刹车，结合速度编码器实时获取车速，并对其运用PD算法进行控制。在转向部分，改进舵机的安装方式为立式并架高。结论证明，智能车实现了前瞻大及转向响应灵敏，能够快速且稳定运行。

Design and implementation of an automatic cruise intelligent vehicle based on vidio

In order to further improve the automatic cruise smart car's speed, in the image acquisition part, we raise the analog CCD camera, reduce its angle of depression, and build a high-speed AD converter circuit outside the microcontroller.In the driving part, use the H-bridge driver circuit to drive the the smart car forward and brake, combined with speed encoder to obtain the real-time speed, and control it with PD algorithm. In the turning parts, improve servo mounting for vertical, and heighten its position. Conclusions prove that the smart car get a greater foresight and a sensitive turning response. It can operate quickly and stably.
