[0061] The specific embodiments of the present invention are described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention. A method for rapid target detection in remote sensing images based on YOLOv2 includes the following steps:
[0062] 1. Make remote sensing image data sets such as figure 1 As shown, the preprocessing, target labeling and data expansion of the collected remote sensing images include the following steps:
[0063] 1.1 Preprocessing: Use the dark channel defogging algorithm to defog the foggy image, and use the MSRCR image enhancement algorithm to obtain the remote sensing image data set with improved clarity and contrast.
[0064] 1.2 Manually label the remote sensing image data set obtained in step 1.1, divide the target to be detected into six categories: airplanes, ships, vehicles, squares, playgrounds, and buildings, record the coordinates of the target location, and compare the targe...
