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.
