Abstract

In this paper, a high-speed condition based on the least square method covers defects and damage detection methods, this method can through visual road surface shape characteristics, fracture characteristics of the cover quickly identify and make analysis and processing.The road image in front of the detection vehicle is obtained at high speed through the two CCD cameras fixed at the top of the locomotive.The image acquisition card converts analog signal to digital signal transmission to the upper computer. The processing center uses the algorithm to preprocess the image and the least square ellipse fitting of the processed image to realize the shape feature recognition, using the calculated pixel area, pixels horizontal and vertical projection, calculation methods of rectangular degree, realize the manhole cover crack identification;The location of the well cover can be indirectly reflected by rotating encoder and GPS location detection vehicle.This method is simple, fast, safe and cost effective for the existing well cover detection technology. It can effectively recognize the loss and damage of the surface well cover and provide support for road safety.
