| China is a country with frequent geological disasters,the disaster caused by collapse of slope dangerous rock usually bring huge losses.Therefore,how to realize long-term slope dangerous rock monitoring in complex field environment has become a key research content.In this thesis,a design scheme of slope dangerous rock monitoring system is proposed.The image detection method is used to monitor the dangerous area and the state information of dangerous rock is obtained in time.At the same time,a set of slope dangerous rock monitoring system equipment is developed to realize efficient and automatic monitoring of slope dangerous rock.The main research contents of this thesis are as follows:(1)In order to solve the detection problem of dangerous rock,a moving target detection algorithm based on adaptive information merging in hybrid color space is proposed.The algorithm can extract the complete target contour,has strong adaptability to the change of the target moving speed,and has outstanding detection performance.(2)In order to solve the tracking problem during the collapse process of dangerous rock in slope,a moving target tracking algorithm based on improved Camshift is proposed.The algorithm can acquire the state information of the dangerous rock in time,realize the reliable tracking of dangerous rock in complex background,and has good stability.(3)This thesis carries out the design of the slope dangerous rock monitoring system.The multi-scene tests in the real field slope environment show that the system can accurately extract the moving dangerous rock and track the dangerous rock collapse process,and meet the system design requirements.The tests verified the feasibility and effectiveness of the system.In this thesis,the design scheme of the slope dangerous rock monitoring system is carried out,the automatic detection and tracking of slope dangerous rock is realized,which has certain practical value in engineering application. |
