Abstract
An imaging platform minimizes inter-frame image changes when there is relative motion of the imaging platform with respect to the scene being imaged, where the imaging platform may be particularly susceptible to image change, especially when it is configured with a wide field of view or high angular rate of movement. In one embodiment, a system is configured to capture images and comprises: a movable imaging platform having a sensor that is configured to capture images of a scene, each image comprising a plurality of pixels; and an image processor configured to: digitally transform captured images with respect to a common field of view (FOV) such that the transformed images appear to be taken by a non-moving imaging platform, wherein the pixel size and orientation of pixels of each transformed image are the same. A method for measuring and displaying 3-D features is also described.
