Hardware Design Of Automatic Target-scoring Terminal Based On DM8127 DSP

The traditional manual target-scoring method has many shortcomings,such as heavy workload,poor security,long target-scoring delay and fairness.With the development of image processing technology,auto-target-scoring technology based on image processing came into being.Compared with traditional manual target-scoring method,the auto-target-scoring technology has significantly improved in accuracy rate and target-scoring delay,which has a high practical application value.Therefore,this thesis designs an auto-target-scoring hardware terminal based on DM8127 DSP processor,implements the real-time auto-target-scoring function in the target training.The system captures the vibration signal of the target through the vibration sensor,collects the image of the target through the CMOS image sensor.After acquiring the image according to the vibration signal,the DM8127 runs the auto-target-scoring algorithm which processes the image to get the target performance.The system also extends Gigabit Ethernet for target performance uploads,and extends the SD card to store images for subsequent further analysis.The test results show that the auto-target-scoring terminal developed in this thesis has high accuracy,strong anti-interference ability and short target-scoring delay.At present,the system has been put into practical use in multiple shooting ranges,which can meet the need of auto-target-scoring in actual target training.
