Projected imaged weapon training apparatus
First Claim
1. Weapon training apparatus including a high optical transmission back-projection screen of high optical transmissivity;
- image projection means operable to form a visible target image on the screen by back-projection, said image including one or more datum points;
means for changing the projected image;
weapon sighting means, directable at the front of the screen by a trainee in a training area, including a weapon discharge trigger mechanism and an optical radiation emitter responsive to operation of the trigger mechanism to direct optical radiation at the screen to impinge thereon in a spot indicative of a simulated projectile impact point;
a television camera, located on the same side of the screen as the projector and having a field of view substantially co-extensive with the image projected by the projector, operable to receive at least a part of the projected target image, reflected from the screen, and radiation forming said impact simulating spot, transmitted by the screen, simultaneously as a composite image; and
scoring analysis means comprising image processing means operable to determine from the camera video signal the positional relationship between the impact simulating spot and said datum points defined on the camera-viewed target scene, data storage means operable to store data pertaining to said positional relationship and review means including the screen and means to cause said projector to project onto the screen for viewing an image of said target scene including the impact simulating spot in the positional relationship therewith determined by the image processing means.

Abstract
Apparatus (FIG. 1), for training in the rapid and accurate reaction to a situation confronting one or more trainees 12, 12'"'"' in an enclosed room 11, has one wall thereof formed by a screen portion 14 onto which an optical image is back-projected by projector 16. Each trainee'"'"'s weapon 22 has a light emitter 24 responsive to firing the gun (containing blanks) at the screen to simulate the projectile impact point by spot 26. A television camera adjacent the projector and viewing the rear of the screen receives the spot and relates the position of this within the camera field to datum points of the projected image, the datum points 36'"'"' being visible to the camera and not the trainee. The scoring is analyzed by projecting onto the screen recorded video images including both the spot 26 and the reflected projected image and a store 29'"'"', containing the positional relationships between datum points and target areas, may be used with image processor 28 to determine quantitative relationships between simulated impact point 26 and the target area. A plurality of trainees may use the system together, each being allotted a light emission time window, synchronized with the camera scan to discriminate between them.
