Three Dimensional Measurement Based on the Binocular Vision
测量 立体视觉 线段匹配 小波变换 Measurement Binocular stereo vision Sub-line segment matching Wavelet transformation
摘要
以双目立体视觉理论为基础,提取立体图像的Harris角点作为特征点,经过基于小波变换的子线段匹配方法,采用由粗到细的匹配策略匹配端点,盒滤波技术加速法,解决了匹配准确度和匹配速度之间的平衡问题.采用该方法对水泥冷却机内熟料进行测量,实验表明该方法能够较精确的对物体实现三维测量.
Abstract
The binocular stereo vision theory is used as the bases of extracting the Harris corners of 3D image as featrue points.The subset-line matching method based on wavelet transform,the matching-endpoints method of coarse-to-fine matching strategy and box-filtering accelerative technique are applied.Finally the balance problem between matching accuracy and speed is solved.This solution is deployed to measure the clinker in cement cooler.The results show that the method can realize a more accurate 3D object measurement.
