智能车是智能交通系统(ITS)中的关键环节,智能车自主驾驶技术在公路管理、交通运输等方面有着广阔的应用前景。路径识别跟踪技术是智能车发展的一个重要标志。给出以OV7620作为智能车的主传感器,以红外对管作为辅助传感器对赛道的信息进行采集。OV7620把赛道的亮暗程度转化成像素的灰度值,采用边沿跟踪检测图像处理算法。实验表明小车可以实现任意路径识别与智能行驶。
Smart car is the key link in Intelligent Transportation System (ITS). Smart car autonomous driving technology has broad application prospects in highway management and transportation. Path recognition tracking technology is an important symbol of the development of smart cars. Given OV7620 as a smart car’s main sensor, the infrared tube as an auxiliary sensor on the track information collection. OV7620 the brightness of the track into a pixel gray level, the use of edge tracking detection image processing algorithms. Experiments show that the car can achieve any path identification and intelligent driving.
