Method for evaluating shot pattern on target of shooting ground for sports shooter, involves superimposing images, and detecting and evaluating difference in brightness of superimposition of images by image processing system

摘要

The method involves inverting images for comparing the images accommodated before and after impact of a projectile. The images are superimposed, where an image processing system (7) detects and evaluates difference in brightness of superimposition of the images. Image noises are suppressed, and distance of a target (2) to lift gates and/or size of the target are detected. The detected image is processed as a black-white-image, and dispersion size is detected. Signals of an image processing device (5) e.g. digital video camera, are supplied to the processing system. An independent claim is also included for a device for evaluating a shot pattern on a target of a shooting ground.
