摘　　要：针对胶带输送机运动中的跑偏、扭曲等异常问题,提出一种基于视觉计算的胶带输送机智能监测与预警方法。首先利用高斯滤波建立场景模型,并应用背景减除法提取目标图像。然后使用Shi-Tomasi算法检测目标图像中的角点,并利用金字塔LK光流法跟踪检测到的角点。最后根据摄像机成像原理将角点坐标从图像坐标系转换至世界坐标系下,计算出角点的运动速度。根据胶带运输机上角点的速度判断输送机是否正常运行,并在必要时发出预警信息。实验结果表明该方法能够较为准确、实时地计算出输送机上胶带的运行速度。To resolve the problem of belt conveyor's belt running deviation and distortion,we propose an intelligent monitoring and warning method of belt conveyor based on visual computing.Firstly,the video images of belt conveyor in coal mine are preprocessed and the Gaussian Filter is used to establish the background model.Then,the background subtraction method is applied to get the target image.Secondly,the Shi-Tomasi algorithm is used to detect the corners of the target image and these corners are tracked by the method of Pyramid LK optical.Finally,these corners'coordinates are converted from the image coordinate system to camera coordinate system according to the principles of imaging.And we can get the speed of these corners and judge whether the belt conveyor is in a good condition or not according to the corners'speed and then send out some warning information in time when the running belt conveyor is abnormal.The experimental results show that the proposed method has higher veracity and real time quality.
