摘要
针对煤矿井下液压支架工况复杂,高度检测和控制难度较大等问题,提出一种巷道环境下液压支架高度非接触式测量方法。该方法采用基于双边滤波的单尺度Retinex图像增强算法得到增强图像,再对增强图像进行边缘检测、PPHT处理,求解出液压支架结构件的真实角度,间接测量出液压支架高度。实验结果表明,该液压支架高度测量方法可有效地煤矿井下视频图像中进行测高,且误差小于2 mm。
As for the problems of complex working conditions and larger difficulty in height detection and control of hydraulic support for underground coal mine,a non⁃contact measuring method for the height of hydraulic support under the roadway environment is proposed.In this method,the single scale Retinex image enhancement algorithm based on bilateral filtering is used to obtain the enhanced image,and then the edge detection and PPHT processing of it are carried out to solve the true angle of the hydraulic support structure component and indirectly measure the height of the hydraulic support.The experimental results show that the height measurement method of the hydraulic support can effectively measure the height in the video image of underground coal mine,and the measurement error is less than 2 mm.
