| 摘 要： | 针对线结构激光扫描系统标定成本高,而双目立体视觉测量中立体匹配难的问题,提出了在双目立体视觉的原理上,结合线结构激光扫描的方法实现对被测物体的三维测量。该方法采用张正友相机标定方法对系统进行立体标定;采用BOUGUET’S法对左右相机图像进行立体校正;运用重心法进行激光中心线的精确提取。在图像校正的基础上,可快速实现激光中心线位置的立体匹配;再结合线扫描原理可完成对物体的扫描工作。最后,使用该系统对具有复杂自由曲面的鞋楦进行测量,结果表明:该方法能快速准确地测量出符合要求的三维数据。

| Abstract: | Aiming at the high cost in calibrating linear structured laser scanning system and the difficulty of stereo matching problem in binocular stereo vision,a 3D measurement method based on binocular stereo vision is proposed combining with linear structured laser scanning to obtain the 3D data of the object.The method applies zhang's camera calibration method to be applied to carry out the stereo calibration of the system,and BOUGEST method is adopted to rectify the captured images.With barycenter method laser ... |
