| 摘 要： | 根据双目视觉原理,开发了基于双目视觉的三维尺寸测量系统.利用图像帧差法实现目标物体自动检测;并在此基础上利用立体匹配算法计算出目标物体区域的视差,对生成的初步视差采用基于最小二乘法的视差优化算法,获取目标物体区域的完整视差图;再将三维点云重投影到二维平面,利用最小外接矩形完成目标物体尺寸的自动测量.实验表明,在合适的测量距离下,系统测量精度达到了较好的效果,验证了该系统的可行性.

| Abstract: | The 3D size measurement system is developed according to the principle of binocular vision. Firstly, the target is automatically detected based on frame difference method. And the stereo disparity is calculated from the image target area by using stereo matching method. Secondly, the initial disparity map is improved by utilizing the least square method. The complete disparity map of the image target area is obtained. And then, the three-dimensional point cloud is re-projected onto a 2D plane. Finally, The size of the target can be automatically measure by making use of the minimum circumscribed rectangle. Simulation results show that the improved system can achieve good results, and it is feasible. |
