All-time automatic target scoring system and ammunition drop point positioning method thereof

Abstract

The invention relates to an all-time automatic target scoring system and an ammunition drop point positioning method thereof. The invention relates to the technical field of photoelectric measurement, a GPS positioning technology is introduced on the basis of passive cross positioning of an infrared camera, GPS positioning is carried out on an observation station, a target and a reference point, a passive cross positioning model is established on the basis, the limiting conditions of a system for a working environment are reduced, and the applicability of the system is enhanced; a three-dimensional aerial motion track of an ammunition target is generated by performing preprocessing, target detection, track association, space-time calibration, cross positioning and tracking on infrared images of each observation station, and ammunition drop point positioning and target scoring are performed according to target GPS information after ammunition landing explosion, so that measurement errors caused by inaccurate positioning of ammunition drop point pixel points due to landing explosion are avoided. The target scoring system has few working environment limiting conditions, is high in expandability and applicability, facilitates generation of instructive target scoring information, is high in positioning method precision, and is suitable for popularization and application in a target range.

Description

technical field [0001] The invention relates to the technical field of photoelectric measurement, and relates to an all-day automatic target reporting system and a method for locating the falling point of ammunition. Background technique [0002] Ground assault training is an important means of combat personnel's military combat capability. Taking ground assault training as an example, the airborne platform mounts ammunition, and conducts flight training according to the training plan. According to military learning theory and combat strategy, combatants throw ammunition at the ground target at an appropriate air position, and the ammunition flies quickly in the air. , and finally fall to the ground of the shooting range under the action of the earth's gravity. At this time, using various technical means to obtain the location of the ammunition drop point and report the target has become an effective way to evaluate the combat methods and combat strategies in the training. ...

AI Technical Summary

Problems solved by technology

However, for military training applications such as airborne ammunition ground-to-ground assault, the ammunition target explodes after landing, which will lead to the inability to accurately locate the pixel position of the target landing in the station image based on the above-mentioned traditional method, so as to estimate There will be a large error in the three-dimensional space position of the target landing point
