specific Embodiment I

[0075] Specific embodiment 1: as Figure 1~4 , figure 2 new bullet hole image relative to figure 1 There is a new bullet hole in the still image below the 9-ring area, and the difference between the two images is used to binarize the image to obtain the binarized image after the difference, such as image 3 . It can be seen by the naked eye that the position corresponding to the new bullet hole is a non-zero pixel-intensive area, and the average value of the edge coordinates of the non-zero pixel area is used as the seed. figure 2 Region growing on the new bullet hole image, we can get Figure 4 According to the image shown, the ring number area to which the new bullet hole belongs can be obtained. According to the previously determined target paper template, the position of the ring number mark in the ring number area can be known, and the obtained position image can be compared with the digital template to obtain the ring number area of ​​the area. At this point, the v...

Abstract

In order to solve the defects of high cost of consumable materials and easy damage of equipment of intelligent target reporting system in the prior art, the invention provides a bomb point positioningmethod based on image recognition, which is characterized by comprising the following steps: S1, selecting bullet type before firing, corresponding to bullet hole template in a database; 2, collecting target paper image through an image acquisition device, and comparing that target paper image template store in a database to identify the target paper; at that same time, the digital template of the re number in the target pap image being determined according to the target paper template; S3, capturing continuous images stored in the image processing device, comparing each frame image with theprevious frame image separately, judging whether the target paper is shaken or not, and if the target paper is shaken, starting a new bullet hole identification process to generate position information of the new bullet hole; S4. the position information of the new bullet hole being sent to the server, and the server sends the position information to the display mechanism to complete the display.The invention has the advantages of high reliability and low cost.

Description

technical field [0001] The invention relates to the field of intelligent target reporting devices, in particular to a bullet point positioning method for frame-by-frame comparison of images. Background technique [0002] At present, the army's light weapons shooting training is mostly carried out in the form of target trenches and mechanical lifting targets. Play for 10 rounds, finish 1 round, record the results of 1 round, re-process the target paper, and play the next round. According to rough statistics, the time for recording scores and processing target papers accounts for more than 70% of the total training time, which severely restricts training efficiency. There are also greater safety risks in night training. [0003] The application level of the automatic target reporting system is relatively low, and it is mainly used in the training of a single subject. The difficulty lies in its high technological content and relatively high cost; Automatic target reporting s...
