Escape vehicle rapid identification and tracking method based on vehicle-mounted unmanned aerial vehicle

Abstract

The invention discloses an escape vehicle rapid identification and tracking method based on a vehicle-mounted unmanned aerial vehicle. The method specifically comprises the steps of (1) constructing a prediction model for the position of a road section where an escape vehicle is located, and taking the first three areas with the largest probability values as candidate areas; (2) scanning vehicles in the three candidate areas and uploading the vehicles to a cloud end through a 5G network; (3) establishing a lightweight escape vehicle re-identification model based on the improved DenseNet121, and performing vehicle feature extraction and re-identification on a picture of each candidate area based on the escape vehicle to be queried; and (4) transmitting the position information of the candidate area where the picture with the highest escape vehicle re-identification rate is located to an on-duty person, and completing tracking of the hit-and-run vehicle. The unmanned aerial vehicle can rapidly and reliably re-identify the escape vehicle, and the case solving efficiency is improved.

Description

technical field [0001] The invention relates to the fields of vehicle tracking and vehicle re-identification, in particular to a method for quickly identifying and tracking escaped vehicles based on a vehicle-mounted drone. Background technique [0002] At present, with the continuous growth of the number of vehicles and drivers, the situation of traffic safety is becoming more and more serious; the proportion of serious injuries caused by traffic accidents and escapes is increasing, which not only brings huge economic losses, but also brings a series of social problems . Under the severe background of shortage of public security officers and remote roads, the technical tracking of hit-and-run vehicles is particularly important. How to hunt down escaped vehicles efficiently and intelligently has also become an urgent issue that deserves attention and needs to be solved. [0003] The rapid development of computer vision and machine learning has also brought new ideas to the...
