METHOD AND APPARATUS ENABLING ARCHERY PRACTICE

摘要

An archery practice device simulates dynamic targets, such as in an animal hunt, on a visible screen (14). A video disk (37) contains a plurality of hunting scenes which are projected via a video projector (13) on a vertical screen (14). The screen images are comprised of pixel areas arranged in horizontal rows and vertical columns. A source of light (18) of a spectrum outside the humanly visible range is provided adjacent the screen. Arrows (17) penetrating this light field reflect light to a detector (21) sensitive only to light of said spectrum. Upon detecting such reflection, the scene frame is frozen on the screen (14). The frozen frame is coordinated to the signal from the light detector (21), whereupon a hit zone image is projected to indicate an arrow impact point relative to the frame image to show the scoring of the point of arrow impact.
