【摘要】：提出一种基于声光扫描技术实现三维视频激光雷达系统,克服了基于传统扫描方式的三维成像激光雷达应用中所面临的成像速度慢、体积大、质量大等问题。采用二维声光扫描技术,大大提高了扫描速度;同时,采用高精度的时间差检测芯片,精确测量激光脉冲飞行时间,从而获得高精度的距离值,实现高精度的三维视频成像。详细描述了系统的原理、组成部分以及实验结果。在图像分辨率为63pixel×63pixel时,该系统三维成像速度达到25frame/s,实现视频三维成像,能够满足对成像速度要求较高的特殊场合的需求。
[Abstract]:A 3D video lidar system based on acousto-optic scanning technology is proposed, which overcomes the problems of slow imaging speed, large volume and large quality in the application of 3D imaging lidar based on traditional scanning mode. The scanning speed is greatly improved by using two-dimensional acousto-optic scanning technology. At the same time, high precision time-difference detection chip is used to accurately measure laser pulse flight time, thus obtaining high precision range value and realizing high precision 3D video imaging. The principle, components and experimental results of the system are described in detail. When the resolution of the image is 63pixel 脳 63pixel, the 3D imaging speed of the system reaches 25frames, which can meet the need of special occasions with high imaging speed.
