Research Of High Voltage Transmission Line With External For Damage Based On Bonocular Vision

Today,the country's economic construction has developed rapidly,the public infrastructure widespread implementation of large-scale construction machinery for high voltage transmission line damage especially,specifically including the construction of infrastructure projects such as vehicles,construction,environment greening,pose great threat to high voltage transmission line,the transmission line with external force damage is faced with great challenge.Due to the above problems,research and solve,be badly in need of new technology based on monocular vision is proposed research of high voltage transmission line with external force damage.This thesis on the basis of the study of monocular vision,around the edge detection and image characteristics monocular visual range two key problems were studied.First of all,the thesis analyzes the edge character of monocular vision technology to detect obstacles and monocular vision distance measuring,the research development of two major problems for high voltage transmission lines and preventing broken force existing methods are summarized;Then,according to the image environment are analyzed and the key technology are introduced,with emphasis on various edge detection algorithm has carried on the contrast research,to provide comprehensive literature research foundation,in view of the image characteristics under the environment of high voltage transmission lines,this thesis proposes a fusion algorithm based on Log operator and morphological edge detection,target through and li-jun jin foreign body in transmission lines based on aerial image recognition article putsforward an improved Otsu based on mathematical morphology(the categories)image segmentation algorithm,the experiment analysis and comparison,this method can better application in transmission lines under the condition of transmission lines inspection and detection of transmission line below the target;Finally,the measure of transmission lines and the distance between the obstacles,through the establishment of the camera imaging model,application of small hole imaging principle,the constant distance measurement method based on single camera Angle carries on the thorough research,achieve the obstacles of the transmission line and real time range.
