摘要: 建立了一种并联机器人位姿立体视觉测量系统框架,主要包括图像采集与传输、摄像机标定、尺度不变量特征变换(SIFT)匹配、空间点重建和位姿测量五个部分。该系统基于SIFT,能够很好地处理图像在大视角有遮挡、平移、旋转、亮度和尺度变化时的特征点匹配,有较高的匹配精度,特别适用于对并联机器人多自由度和空间复杂运动的检测。最后使用该方法对并联机器人位姿检测做了仿真实验。

Abstract: This paper presents a framework of scale-invariant feature transform based stereo vision position and orientation measurement system for parallel robot.It is composed of image gather and transfer,camera calibration,Scale-Invariant Feature Transform(SIFT),reconstruction of points and position and orientation measurement.This framework is mainly based on SIFT.It performs reliable matching between different views of objects,when the images have change in scale,rotation,shift and change in illumination.It is especially adapt to measurement for multiple DOF parallel robot and complex motions in space.In the end,position and orientation measurement for parallel robot is realized on the matlab.

Key words: SIFT, stereo vision, position and orientation measurement, 6-DOF Parallel Robot
