Problems solved by technology
[0002] In the pan-tilt monitoring and alarm detection system based on machine vision, when matching the ground line between the panorama image and the depth map, due to the complex terrain of the application scene, and the poor angle of image acquisition or weather reasons, it is easy to cause the captured image to be out of focus. The ground line is not displayed clearly in the panorama, which may lead to mismatching or difficulty in finding the corresponding ground line, which will lead to the wrong positioning of the target position of the ground object, causing interference and inestimable consequences to the subsequent processing

The invention discloses a ground line matching method and device based on a three-dimensional remote sensing image. The method includes: obtaining a curve segment to be matched to represent a ground line selected by a user through a human-computer interaction interface in a depth map; Correspondence between the map and the DEM data of the 3D remote sensing image. Mark the reference curve segment of the ground line corresponding to the curve segment to be matched on the 3D remote sensing image; obtain the ground line selected by the user through the human-computer interaction interface in the panorama Matching curve segments with reference to the ground lines corresponding to the curve segments; matching the ground line matching curve segments in the panorama image with the to-be-matched curve segments in the depth map to obtain the coordinate mapping relationship between the panorama image and the depth map. The invention also discloses a three-dimensional remote sensing image-based method for locating the object position of ground objects. The present invention can more intuitively find the ground line corresponding to the ground line to be matched in the depth map in the panorama image, which is beneficial to the precise positioning of the longitude and latitude of the target position of the ground object.
Description
technical field [0001] The present invention relates to the technical field of ground object location positioning, and in particular to a ground line matching method and device based on three-dimensional remote sensing images and a ground object location positioning method. Background technique [0002] In the pan-tilt monitoring and alarm detection system based on machine vision, when matching the ground line between the panorama image and the depth map, due to the complex terrain of the application scene, and the poor angle of image acquisition or weather reasons, it is easy to cause the captured image to be out of focus. The ground line is not displayed clearly in the panorama, which may lead to matching mismatch or difficulty in finding the corresponding ground line, which will lead to the wrong positioning of the target position of the ground object, causing interference and inestimable consequences to the subsequent processing.
