Abstract

The invention discloses a changed building rapid detection method based on new and old time phase images of an unmanned aerial vehicle; the method includes obtaining an old time phase image obtained before a current moment and a new time phase image obtained at the current moment; performing rough matching based on Kalman filtering; determining a rough matching image area of the new time phase image in the old time phase image; and based on a k-d index tree, carrying out accurate matching on the rough matching image region and the new time phase image, obtaining a time-phase corresponding region of the new time-phase image in the old time-phase image; taking a time-phase corresponding region as a reference image; performing geometric correction on the new time phase image; performing relative radiation correction between images based on brightness correction model construction and a color balance method. A pre-trained recognition model is adopted to recognize the old time phase image and the new time phase image after radiation correction so as to determine a suspected changed building area, rapid detection of a changed building is realized, and the corresponding detection processhas relatively high accuracy.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for quickly detecting changing buildings based on new and old phase images of drones. Background technique [0002] In response to the current problem of illegally abusing land to build and expand buildings, relevant departments have also taken many measures to comprehensively supervise, increase supervision, and strengthen dynamic supervision through various means, so as to detect changes in buildings in time and improve Work efficiency, to achieve "timely discovery, timely report, timely stop, timely processing". In order to grasp the status of land changes in time, it is necessary to monitor and control the land. Traditional UAV land monitoring requires manual selection and deployment of a large number of control points, and large-scale splicing of images to complete change detection, which is time-consuming and labor-intensive. Contents of the invention [0003...
