| Live-fire training is an important part of modern military routine training and its main training course, which is mainly used to testify the trainees’controlling of the weapon and equipment through the accuracy of their hitting degree. Currently, most of the troops still use manual target-scoring system as its main pattern in live-fire training. However, manual target-scoring system has its disadvantages when used in the wild live-fire training, such as low efficiency, inaccurate score as well as some potential safety hazards.In light of all the disadvantages of manual target-scoring system, experts at home and abroad have done many researches and put forward a variety of designing schedule of automatic target-scoring system, such as photoelectric target-scoring system, acoustoelectric target-scoring system and laser target-scoring system, etc. However, because of their high cost, difficulty in operating and system arranging, etc. it is not easy to popularize them. At present, the automatic target-scoring system based on image processing has drawn a lot of attentions because of its simple hardware structure of the system, the convenient design and maintenance of software as well as its low cost. But because of its low recognition rate and weak adaptability to the environment, it has not been widely used yet.According to the above questions, this paper proposed a kind of designing schedule of intelligent target-scoring system based on DSP image processing and CAN bus. This system has realized a integrate process of intelligent target-scoring system, from the data acquisition, image processing and bullet identification, to real-time display, real-time data managements and statistics. The whole system consists of four parts, and they are PC management software, image processing subsystem, intelligent display subsystems, and automatic target changing mechanical equipment. Each subsystem is connected to the network through the CAN bus to realize modularization, intellectualization, miniaturization and facilitation of the design of the whole system. This paper mainly researched the design and application of the PC management software, image processing subsystem and CAN communicating network. As for design of the software, PC management software is mainly used to realize system management and data storage. During image processing, image processing algorithms such as binarization, Gaussian filter, edge extraction are adopted, combining with the characteristics of the chest silhouette image, which realized bullet hole recognition scheme with high recognition rate. In the aspect of system communication, this paper designed CAN bus communication protocols in application level with high real-time performance and high reliability based on the analyzing and researching on the communicating mechanism and principle of CAN bus to adapt the target-scoring system and ensure that the system is stable and reliable for data packet transmission.After a lot of research and system integration testing experiments, we can find that the overall design of the intelligent target-scoring system and its related algorithm is feasible and can meet the actual demand of live-fire training. This system not only takes the characteristics of the troops ’live-fire training into consideration, but also has high indication accuracy and steady and reliable communication system. In addition, this system adopts modularized and intelligent design, which made the system not only simple to layout and easy to maintain but also convenient to outdoor environment, thus it boasts certain academic and practical value. |
