摘要
无扫描3-D距离选通成像激光雷达能有效抑制后向散射,消除距离模糊,提高系统的探测能力、成像质量和距离精确性。介绍了完全采用商用器件搭建的无扫描3-D距离选通成像激光雷达实验系统,对实验系统进行了测试,结果表明:系统在室内40m的作用距离下,距离分辨率达到1.5m,能够准确地获得目标形状和距离信息;在室外960m的作用距离下,系统的距离分辨率下降到3m,但依然能够识别出目标。最后提出了实验系统的不足之处。
Non-scanning 3-D range-gated imaging lidar can improve the detection capability, image quality and distance accuracy of the system by suppressing back scattering and removing fuzzy distance. The non-scanning 3-D range-gated imaging lidar system composed of commercial products is introduced, and the experimental system is tested. Results show that the system range resolution is 1.5 m at 40 m range indoor, and target shape and distance information can be acquired accurately. The system range resolution decreases to 3 m at 960 m range outdoor, however, target can still be identified. Finally, the system＇s shortcomings are pointed out.
