【摘要】 鉴于传统砂轮地貌检测方法所存在的缺陷,提出了一种基于双目图像的磨粒高度检测方法。该方法采用灰度模板匹配算法,通过优化模板尺寸,可以获得较高的匹配率。通过对各种尺寸的模板进行试验研究,得出优化的模板尺寸。使用优化模板对标准试件进行匹配,并对其高度进行估算,试验结果表明,估算误差小于5%。更多还原

【Abstract】 A new approach for calculating the exposed height of grain based on the parallax of binocular images was presented due to the disadvantages of conventional detection methods.To obtain the parallax from binocular images,the algorithm of gray template matching was used,which had excellent matching rate and the window size is the only parameter.The optimum window size is obtained by experimental results.The exposed height of grain can be calculated by adopting the given calibration method,which was obtained on the basis of the optimum window size according to the parallax.The height error is less than 5%,which can satisfy to the engineering requirements.更多还原
