Article Preview

Forward looking collision avoidance radar has been extensively researched by domestic and external. Two-dimensional scanning and controlling method can be applied to front-visual automobile collision avoidance lidar to acquire intensity image and range profile of the targets. But it has some disadvantages of complex system, large volume, high cost and it is difficult in practical applications. In comparison to two-dimensional scanning image system, one-dimensional scanning image lidar cannot reconstruct 3D image of target, whereas the imaging speed is much more rapid due to less scanning points. In this work, a one-dimensional scanning semiconductor imaging lidar system was developed, which was composed of laser system, optical system, scanning system, detecting system and signal processing system. Real-time intensity images of black and white stripe targets were obtained in the laboratory. The study results provided foundation for further practical application. This lidar system owns the advantages of simple structure, high speed imaging, low cost, etc. It can be promisingly applied in forward looking automotive collision avoidance lidar system.
