Abstract： |
The invention is a kind of car scanning laser radar detecting system and the method for detecting forward dangerous which belongs to car traveling information sensing and processing technology field. The character lies in: the scanning component contains two scanning lens and step-by-step motor which drives the lens to rotate, the instruction output end of the controller control the step-by-step motor to rotate and stop through driving circuit; the step-by-step drives the scanning lens to rotate through a convex wheel mechanism and a V type pendulum rod. Thus the laser is used to scan in a fixed angle range. The invention uses the time difference sent by the laser and reflected by the target to calculate the target object distance, uses the angle from scanning to the status reflected by the target object to calculate the object position angle, and finally outputs the distance and position angle information of danger. The system can realize the scan in wide range, the cost is low. The method can identify the dangerous object effectively. |
