Automatic Target Reporting Technology And Gun Calibration In Shooting Training

The application of automation technology in the shooting training process can not only improve the efficiency of shooting training,reduce the risk of safety,but also help the shooter to master the hit situation in real time,adjust the shooting action in time and improve the training effect according to the hit situation.This paper includes two main research contents: 1.automatic target shooting during the firing process;2.gun calibration before firing.Study on a target,with automatic target reporting,fire command and control function of the target drone lifting control system.In terms of gun calibration,we have studied a kind of gun calibration system that can automatically calculate the amount of firearms correction and apply to ordinary shooters.Based on the image processing technology to research the key range bullet hole recognition control system and gun calibration system.The main work of this paper includes the following contents:According to the actual demand,a design scheme of the range control system is proposed.The hardware platform part of the system is briefly expounded,and the system management software part is divided and programmed.In view of the fact that the current gun method can not meet the actual demand of shooting,this paper presents an improved method for calculating the correction of firearms,derives the calculation formula for the correction of the firearms,and designs the overall design of the gun system based on computer automatic recognition and calculation.Automatic bullet hole recognition first target image preprocessing.Aiming at the complicated background area of target image,we extract the target area preliminarily.In view of the geometric distortion of the target image,an improved method of geometric correction of the target image is proposed.The corrected target image is consistent with the actual physical size and has no distortion.An improved adaptive enhancement algorithm for target image is proposed.According to different illumination conditions,the adaptive enhancement of the target image is made,and the visual effect is improved and the recognition of the bullet holes is also beneficial.For the problem of interference in the recognition of the bullet hole based on the silhouette method,the improved method of the bullet hole extraction is proposed.Through two silhouettes,the gray value of the new area of the new bullet hole has a larger difference with the other regions,and then the bullet hole is extracted.In view of the complex situation of the ring value area of the target surface,a method based on the effective region is proposed.The experimental results show that this method has a high accuracy and can meet the practical application needs.
