Whole-course continuous track vehicle tracking system and method based on laser radar network

Abstract

The invention belongs to the technical field of traffic image processing and traffic information, and discloses a whole-course continuous track vehicle tracking system and method based on a laser radar network. The whole-course continuous track vehicle tracking system based on the laser radar network comprises the laser radar network, other roadside sensors, a roadside processor, a fusion server and network communication equipment, the whole-course continuous track vehicle tracking method based on the laser radar network comprises the following steps: synchronizing time; scanning a monitoringrange; performing vehicle multi-target detection; tracking a track; carrying out snapshot and license plate recognition; carrying out event analysis; carrying out coordinate conversion; carrying out encoding the information; reporting detection point information; fusing information in the whole process; and displaying vehicle full course trajectory. According to the invention, real-time and whole-course continuous trajectory tracking can be carried out on vehicles on an expressway, video images in an event occurrence time period can be accurately captured in combination with a camera, timely processing of hit-and-run vehicles is realized, and small time delay, low calculation load and small network transmission load are realized.

Description

technical field [0001] The invention belongs to the technical field of traffic image processing and traffic information, and in particular relates to a system and method for tracking a whole-process continuous track vehicle based on a laser radar network. Background technique [0002] At present, the monitoring and management of passing vehicles is an important work content of expressway management. In order to ensure road safety and effectively reduce the probability of traffic accidents, it is of great value to track the real-time continuous trajectory of illegal vehicles. The existing trajectory tracking technology is mainly realized by video equipment, monitoring points along the expressway, and tracking illegal vehicles through manual inspection or image recognition. Although the application of deep learning technology has greatly improved the recognition rate, it will still be seriously affected in scenes with poor ambient light, which poses a major obstacle to the co...

Problems solved by technology

[0008] The difficulties in solving the above problems and defects are as follows: the continuous track tracking of the whole process requires all-weather real-time tracking of the vehicle without dead ends, and the video technology is limited by the ambient light conditions, which makes it impossible to realize; the roadside radar coverage of a single monitoring point is limited, and for It is also difficult to meet the requirements of continuous trajectory tracking in the real-time connection of multiple radar boundaries
