ABSTRACT:
A passive range measurement device and method are described which utilizes a digitized image stream derived from images taken by a camera which is also part of the device. The device also includes a digital processor which operates on the image stream to extract the coefficients of an address modification function from which range to each point in the scene, relative camera-scene, and camera-platform orientations may be derived. The extraction process is based upon calculation of a vector field which describes the pixel-to-pixel misregistration between two images. Improvements in the modification function are found from global, then localized averages of the vector field. Thus, a topographic map of the scene which is referenced to the position of the camera and platform is created, and may be used to create a terrain following capability.
