Producing realistic display for road traffic simulation - using computerised modification of projected scene to correspond to deviation of learner-driver from straight course.

摘要

The driver under instruction sits (3) at a panel with dummy controls including a steering wheel (4). The video image back-projected (2) from a disc or tape (5) on to a display screen (1) is based on actual photography with a camera travelling at uniform average speed in the centre of a road. Variations of the image are introduced by a computer (7) with a keyboard (8) and video monitor (9) in accordance with imaginary movements (6) at right angles to the direction of travel. ADVANTAGE - Centre-oriented basic image information is modified at less cost by applications of mathematical model and computerised control.
