智能汽车的“眼睛”
智能汽车的“眼睛”是装在汽车右前方、上下相隔50厘米处的两台电视摄像机,摄像机内有一个发光装置,可同时发出一条光束,交汇于一定距离,物体的图像只有在这个距离才能被摄取而重叠。“眼睛”能识别车前5——20米之间的台形平面、高度为10厘米以上的障碍物。如果前方有障碍物,“眼睛”就会向“大脑”发出信号,“大脑”根据信号和当时当地的实际情况,判断是否通过、绕道、减速或紧急制动和停车,并选择最佳方案,然后以电信号的方式,指令汽车的“脚”进行停车、后退或减速。智能汽车的“脚”就是控制汽车行驶的转向器、制动器。
The "eyes" of a smart car are two TV cameras installed in the front right of the car and 50 centimeters apart from the top and bottom. There is a light emitting device in the camera, which can emit a light beam at the same time and intersect at a certain distance. Only at this distance can the image of the object be taken and overlapped. "Eye" can identify obstacles with a platform plane between 5 and 20 chengdu.89ix.com guizhou.89ix.comkunming.89ix.com hangzhou.89ix.comnanchang.89ix.comguangzhou.89ix.commeters in front of the car and a height of more than 10 centimeters. If there is an obstacle ahead, the "eye" will send a signal to the "brain", which judges whether to pass, bypass, decelerate or emergency brake and stop according to the signal and the actual situation of the local area at that time, and chooses the best plan, then instructs the "foot" of the car to stop, retreat or decelerate by means of electrical signals. The "foot" of intelligent vehicle is the steering gear and brake that controls the vehicle.
