Ball firing system and hit point calculation method based on topology grid learning

Abstract

The invention discloses a ball firing system and a hit point solving method based on topology grid learning. Wherein, the method comprises: projecting grid sample images on a projection screen, processing to photographing for the sample images, and collecting position data of each grid endpoint; analyzing the position data of each grid endpoint corresponding in the sample images and sampling images, and establishing a nonlinear topology grid mapping relationship between the simple images and the sampling images; detecting the hit point on the projection screen via a camera, and processing a photographing aberrance restoration for position of the hit point in photographing images according to the topology grid mapping relationship, and solving out an exact position of the hit point on the projection screen relative to a mapping image. The invention effectively corrects errors caused by the photographing images generating image aberrance, and can detect the hit point on the projection screen via the camera through establishing a coordinate solving model of high accuracy photographing image and the mapping image, so as to process quick and real time position solving.

Description

Technical field [0001] The present invention relates to a technology for repairing camera image distortion, in particular to a method for correcting errors caused by image distortion caused by camera image based on topological grid learning, and accurately calculating the position of the hit point in the camera image, and a method using the method Live ammunition shooting system in virtual scenes. Background technique [0002] The guiding ideology of combat based on effects has introduced a large number of wars into cities, and the special environment of complex streets and numerous buildings has made urban combat pose unprecedented challenges to the military. Traditional live ammunition training can no longer meet the needs of future military struggles, nor can it effectively meet the needs of the garrison to perform defense. The virtual scene live ammunition training has become a new training method, which can simulate various special environments such as urban streets, buildin...
