Target positioning method and related device

Abstract

The invention discloses a target positioning method and a related device, and the method comprises the steps: obtaining a first image and a second image, and enabling the first image and the second image to be shot at a first position and a second position for a same target object; obtaining the distance between the first position and the second position obtained by the distance measuring equipment; performing feature extraction and matching on the first image and the second image to obtain a first feature point pair set; obtaining a first rotation matrix and a first translation vector according to the first feature point pair set; and determining the direction information and distance of the target object according to the first translation vector, the first rotation matrix, the coordinates of the target object in the first image and the second image, and the distance between the first position and the second position. The invention further discloses a positioning device. When the target positioning method is used for target positioning, a positioning result with relatively high positioning precision can be obtained, and meanwhile, the position of the target is not exposed.

Description

technical field [0001] The present application relates to the field of image processing, and in particular, to a target positioning method and related devices. Background technique [0002] Obtaining the absolute position of the reconnaissance target in the battlefield can not only allow the UAV to carry out precise strike missions, but also serve as information for the navigation and positioning of other weapon platforms. The precise position of the target to be obtained by a single soldier on the battlefield can be determined by calculating the azimuth and distance of the opponent, and the precise positioning of the target can be obtained by combining its own coordinates and azimuth. Most of the existing target localization methods are based on binocular or multi-eye vision systems, and the position information of the target is calculated by solving the limit constraints between multiple cameras. Or by adding a laser range finder to the vision system, it is more convenien...

Problems solved by technology

[0003] In the battlefield, the enemy will use the laser detector to determine the position of the scout. Although the target positioning system using the laser rangefinder and camera can obtain better positioning accuracy, it is also easy to be exposed by anti-reconnaissance.
