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

Abstract

The invention discloses a geographic line matching method and device based on a three-dimensional remote sensing image. The method comprises the steps of obtaining a to-be-matched curve segment selected by a user in a depth map through a human-computer interaction interface and used for representing a geographic line; marking a geographic line reference curve segment corresponding to the curve segment to be matched on the three-dimensional remote sensing image based on a corresponding relation between the depth map and DEM data of the three-dimensional remote sensing image; obtaining a ground property line matching curve segment corresponding to the ground property line reference curve segment selected by the user in the panorama through the human-computer interaction interface; and matching the geolinear matching curve segment in the panorama with the to-be-matched curve segment in the depth map to obtain a coordinate mapping relation between the panorama and the depth map. The invention further discloses a ground object target positioning method based on the three-dimensional remote sensing image. According to the invention, the geologic line corresponding to the geologic line to be matched in the depth map can be more intuitively found in the panorama, and accurate positioning of the longitude and latitude of the ground object target position is facilitated.

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.
