OPTICAL RANGE AND SPEED DETECTION SYSTEM

摘要

A passive optical speed and distance measuring system includes a pair of camera lenses (14, 18) positioned along a common baseline (60) a predetermin ed distance apart and controlled by an operator to capture images of a target a t different times. The camera lenses (14, 18) are focused on light sensitive pixel arrays which capture target images at offset positions in the line sca ns of the pixel arrays. A video signal processor with a computer (30) determine s the location of the offset positions and calculates the range to the target by solving the trigonometry of the triangle formed by the two camera lenses (14 , 18) and the target. Once the range to the target is known at two different times the speed of the target is calculated.
