The Research And Application Of Multi-target Track Tracking Method For Video Of Underground Coal Mine

Coal is not only one of China's basic energy,but also an important pillar of the national economy.Frequent mine accidents caused the state and society to attach great importance to coal mine safety issues.With the rapid development of video surveillance technology,video surveillance technology has been widely used in coal safety production monitoring.Therefore,from the point of view of safety production,this paper studies the video surveillance technology in coal mine.computer information technology is used to reduce the occurrence of coal accidents,to ensure the safety of coal mine production is of great significance.According to the actual situation of coal mine and the characteristics of monitoring video,this paper studies the technology of underground monitoring video.According to the existing problems of monitoring in coal mine,the CamShift algorithm in target tracking is improved.Monitor video target tracking system is developed.The main contents and innovations are as follows:(1)This paper presents an algorithm for multi-target trajectory tracking of coal mine.In order to improve the accuracy of target recognition in coal mine monitoring video,track effectively target,the wavelet transform algorithm and background difference method are combined to improve the CamShift algorithm.Firstly,wavelet transform algorithm is used to denoise the video image.And then perform the background difference method to detect the moving target.Finally,CamShift algorithm is used to track the moving objects.The results show that the improved CamShift algorithm reduces the randomness of the original CamShift algorithm at the initialization phase.(2)In order to cope with the changing environment of coal mine,The technology of video and the characteristics of monitoring video in coal mine are studied.And a variety of target detection technology and target tracking technology are integrated into to develop the video target tracking system.In the system development process,in order to allow users,modular design ideas are used,and the various functions are packaged independently.And the system also provides a warning function,when the moving target into the manual set of dangerous areas,the target will be highlighted to show a warning.This paper has developed a multi-target trajectory tracking system for underground coal mine.The system uses the improved CamShift algorithm to improve the success rate of target tracking.Due to limited personal ability and time,there are still some problems in the system,the future will be further research and exploration.
