摘要
本文主要针对智能小车的红外避障功能存在的"点"避障缺陷,提出并设计了一种基于双路交叉红外探测的智能避障系统.重点针对避障过程中所遇到的"贴墙"陷阱问题,进行深入分析研究,提出了基于时钟中断的保护期模式的解决方案和相关算法.算法经过测试实验反复调整参数,达到了较好的避障效果.
As a robot propelled through 4 wheels, Intelligent Vehicle have a lot of flexibility. The study about the intelligence obstacle avoidance research, which attracts many scholars, was one of the important subjects in the study field of the intelligent vehicle. Intend to solve the defect existing in the function of the smart car of infrared obstacle avoidance, this article puts forward and designed a way of infrared detection based on the double cross intelligence obstacle avoidance system. As for the ＂Wall＂ trapping problem, which the tiny intelligent car come across in the avoidance process, this article solves it effectively by presenting a protection mode based on the clock interruption. The algorithm has been tested again and again to modify the parameters, and achieved a good effect of obstacle avoidance.
