Abstract

3D laser radar has the advantage of acquiring the accurate 3D information of the surrounding environment in a fast manner. However its high selling price restricts its further application in many fields. A fast 3D scanning laser radar is designed and calibrated. The system consists of a 2D laser scanner, a step motor controlled pitching mechanical equipment and a control unit. A specially designed high-speed data transmission board is used to guarantee the high sampling rate of the radar. The inner parameters affecting the accuracy of the system are analyzed and then computed by the least sum of square error algorithm. The experimental results show that the resulting system has high scanning rate and high data accuracy and therefore is a cost effective means to acquire high quality 3D data.
