Vehicle target motion speed detection method based on UAV multi-source images

Abstract

The invention discloses a vehicle target motion speed detection method based on UAV multi-source images. The method comprises the following steps of constructing a UAV multi-source image acquisition platform; acquiring image data by using the image acquisition platform, acquiring the multi-source images of a visible light camera and a thermal infrared camera by using the computer main board of theUAV platform, transmitting the multi-source image data to a ground monitoring client through 4G to complete the real-time acquisition of the images; correcting the acquired image data to reduce the geometric distortion of the image data; registering the corrected multi-source image data; performing weighted fusion on the registered multi-source image data; based on the multi-source image data subjected to the weighted fusion, detecting a vehicle targets; tracking the vehicle target; calculating the motion speed of the vehicle target. The invention provides an easy-to-operate, high-efficiency,flexible vehicle speed monitoring method for a vehicle monitoring and management department.

Description

technical field [0001] The invention relates to the technical field of video image processing, in particular to a method for detecting the moving speed of a vehicle target based on multi-source images of an unmanned aerial vehicle. Background technique [0002] With the continuous development of science and technology, modern transportation is becoming more and more important in economic activities, and with the modernization of transportation, more and more traffic problems have emerged. Under such a large environment, Intelligent Traffic System (Intelligent Traffic System, ITS) emerged as the times require, and researchers from all over the world are actively researching and developing to improve traffic monitoring methods, among which computer vision technology provides important technical support for intelligent transportation systems. The detection of vehicle speed is an important part of the intelligent transportation system, and it is also a hot and difficult point in...

AI Technical Summary

Problems solved by technology

Among them, the detection technology based on the principle of electromagnetic induction is relatively complicated in layout, and the monitoring location is relatively fixed; the relatively high cost of laser and radar detection technology has certain errors, making it difficult to promote in practical applications.

This means that the current vehicle speed monitoring has the problem of poor flexibility of monitoring locations, a certain dependence on lighting conditions, and it is difficult to detect a single vehicle of interest.
