| Shooting training is one of the important training projects in routine military training, at present, the shooting target training is still mainly based on real bullet, and it needs the man to reply the scores to the trainer, its cost is not only expenditure, but the reliability, fairness, and efficiency also can not be guaranteed. As the laser has the characteristics of monochrome, high directivity, high brightness, coherence and so on, it becomes a trend to replace the actual shooting training with the laser bullets targeting system.This issue highlights a realistic simulation training which based on image processing techniques that can be used in real targeting training. The system uses CCD camera to shoot target surface images, converts analog images into digital images by image capture card, and stores in a computer, then through image preprocessing and image recognition sub-target obtains shooting results, namely: shooting rings.The essay makes researches on video image acquisition system and image recognition algorithm of sub-target. It relates the hardware composition and working principles of the video acquisition system in detail, it uses CCD camera and image acquisition card to acquire target surface image, and then sends to PC by video transmission line to process and display in real-time; the essay emphasizes on the methods of image recognition, including identifying the target of the center, calculating ring spacing, judging the center location of laser and shooting ring. Experiments were conducted using the image processing software, developed on the basis of VC++6.0 software, and succeed in scoring it automatically, the friendly user interface achieve real-time display, as well as to query, modify or print the personal information and achievements and so on.Compared with manpower target-scoring, the system was found to be able to improve the credibility and safety and scoring efficiency, and for its low cost, it has good prospects for development and application. |
