Development Of The Mobile Terminal For Automatic Target-Scoring System

With the rapid development of science and information technology, highly automated target reporting system used troops firing training or shooting competitions have been developed. Currently, live fire training of many units still use manual target scoring system, its security is low, heavy workload, the presence of man-made false positives and false negatives, reported target low efficiency drawbacks. Compared to artificial reported target, the automatic target mode is safe, fast, accurate and efficient characteristics.Therefore, the development of automatic target system has become an inevitable trend, and it is very important to improve the training efficiency for shooting and promote the construction of military modernization.In view of the high cost, complex structure, poor portability of the existing target system, and the display terminal is fixedly installed in a computer behind the shooting staff,what is not easy for shooting staff to observe their shooting results in real time. only at the end of the shooting, shooting staff can walk to the display terminal to see the shooting performance. The display terminal is connected with the background management computer through the connection mode of the network cable, so the computer is fixed and there is the existence of a complex network cabling problem, when the shooting end, the computer display terminal is not transferred to the interior, long time exposed in the humid air will affect the service life of the terminal. Because of the inconvenience of computer display terminal, this paper designs a kind of interactive mobile target terminal.This paper introduces the development status of automatic target reporting system,complete the overall design of the system framework, then studied the system core image processing and judging the shooting ring algorithm, proposed image subtraction algorithm to eliminate interference of the target loop, old bullet holes, target surface digital and external factors, reduces the computation load of the system and improve the system performance in real time. Mobile target terminal module is designed and implemented based on the STM32 processor slave computer software framework, programming to achieve the signal control, the data analysis processing, wireless data transmission and communication of mobile terminal, PC handheld terminals designed and implemented interactive interface and complete all the features of interface design, and completed theoverall debugging system terminal interface. Finally, the thesis gets some general conclusions for the whole dissertation and bring up the prospect of the work in future.
