A laser simulated shooting system based on image recognition

Laser simulated shooting system based on machine vision, need to identify laser spot of digital target figure for completing follow-up results display and automatic voice report. However, images captured by camera has distortion, which may cause identification difficulty. In this paper, image recognition algorithm conduct digital target figure correction analysis to get transformation matrix, which is used to do coordinate transformation for laser spot that is acquired with background subtraction based on threshold. After analyzing transformed coordinate on standard target figure, we can report ring number. Approach of this system has been extensively tested on Windows operating system, results are accurate and reliable, which meets the system requirements.
