A road spill recognition method based on three-dimensional information restoration and extraction

Abstract

The invention discloses a three-dimensional information restoration and extraction method for identifying spilled articles on roads. The three-dimensional information restoration and extraction method particularly includes steps of acquiring a video image array of an urban road by the aid of a CCD (charge coupled device) camera; segmenting the video image array by a double-effect layer interactive segmentation algorithm to obtain static foreground target regions; extracting static foreground contours by the aid of an eight-adjacent connection region; creating a nonlinear two-dimensional pattern classifier by the aid of geometric shape characteristics of the target regions, eliminating static foreground interference and detecting suspected spilled targets; restoring three-dimensional information of the targets by the aid of a prospective projection matrix; and estimating an optimal ground plane equation by a difference removal optimization robust algorithm, solving extremely high values of the targets relative to the ground and identifying dangerous spilled targets. The three-dimensional information restoration and extraction method has the advantages of high efficiency, flexibility and high cost performance, and a novel idea is provided for developing an efficient intelligent obstacle identifying system.

Description

technical field [0001] This paper involves the fields of intelligent traffic video image monitoring, computer vision technology and 3D reconstruction technology, especially a method for identifying road spills based on 3D information restoration and extraction. Background technique [0002] In recent years, with the continuous increase of expressway traffic, vehicle spillage incidents have occurred from time to time, and traffic accidents caused by spillage and falling objects on passing vehicles have also continued to increase, which will not only make vehicles detour and reduce road operation Efficiency, and more importantly, it will cause safety hazards to other vehicles, because once an accident occurs, it is often easy to evolve into a major traffic accident, causing loss of life and property to passing vehicles and drivers and passengers, and bringing economic losses to the expressway operation and management unit. Losses and litigation disputes have increased the diff...

Problems solved by technology

With the popularization of video sensors installed on urban roads, expressways and tunnels and the continuous development of video surveillance technology, traditional artificial video surveillance can no longer meet the needs of real-time discovery of traffic abnormalities. Therefore, making full use of existing monitoring equipment, research The detection technology of spilled objects based on video image sequence can not only obtain more traffic status information, improve the current backward situation of video surveillance, but also improve the value of equipment, prevent traffic hazards in advance, and ensure safe and efficient operation of traffic roads
