    A novel laser difference—frequency scanning underwater 3-D vision sensing system based on the original developed wide field angle panoramic underwater laser TV is described. The 3-D measurement of panoramic large field (underwater 25°×28°) can be realized when the 2-D image is provided.Using 3-D scanning receiving unit and photomultiplier as high sensitive narrow field rece- iver, so the base line leingth can be adjusted, and the light in underwater scattering background can bo overcome. The measuring range of the system is equivalent to 3~4 attenuation lengths in muddy water.

    It is very important that the 3-D visual sensory system in visual robotics field is designed. In this paper, a TV camera and a 3-D teaching device with four LEDs attached to measured Point on the object are employed to acquire the 3-D information of the measured point. The algorithm of the position and orientation in space is based on vector analysis and Perspective transformation principle. The advantages of the algorithm are high reliable, time saving, simple and practical. The calibration of the camera is also discussed in this paper. The correct parameters of the camera are obtained by decomposed matrix method and Least Square method, which is proposed by author. The calibration method is better than non iterative matrix analytic method.

    三维视觉传感系统在机器人视觉领域有着重要的意义和实用价值。本文采用单摄像机与3-D示教器(由四个LED构成)组成的仿真三维视觉传感装置来完成空间坐标系中物体的空间位置和姿态的测量。将3-D示教器坐标,机器人坐标及摄像机坐标用透视变换进行坐标变换及LED的几何关系来求取被测对象的空间位置和姿态。本方案具有简单,快速,可靠的特点。为机器人视觉形成反馈提供了可操作的实用方法。本文对摄像机模型参数的求取进行了探讨,提出了用矩阵分解及最小二乘法来实现视点的标定。其算法结构优于非迭代矩阵分解算法。
