1. A computer controlled imaging system responsive to the position and orientation of a scene recognition means comprising:
- a data base having a defined area with a digital three coordinate system and a library having a plurality of rectangular two dimensional image frames of electromagnetic spectrum band representation of images;
said defined area part of said data base having scene composition data which defines the location and size of each of said image frames relative to said coordinate system;
simulation means for supplying position vectors and rotational observation data defining the location and the field of view of said scene recognition means relative to said defined area coordinate system;
interface means for receiving said observation data;
field of view processor means associated with said interface means and said data base, said field of view processor means including a second three coordinate system and means for determining which of said image frames are included in said field of view and their respective ranges relative to said observation data and said frame data to compute four corner coordinates in said second three coordinate system which correspond to the defined area coordinates of the corners of each said included image frames;
controller means connected to said field of view processor and including means to receive data therefrom;
said data including the identity of said image frames included in said field of view, said ranges of said included image frames and said coordinates of each of said included image frames;
said controller means being further connected to said library part of said data base;
processing channel means controlled by said controller means connected to said library part of said data base wherein said library part of said data base is connected between said controller means and said processing channel means, said channel means operating to map said included frames to the enclosed space defined by the corresponding ones of said corner coordinates; and
scene construction means connected to said processing channels for assembling an output scene based on said ranges of said included frames on a digital basis such that the included frame nearest said scene recognition means includes more distant ones of said included frames.

Abstract
The disclosure relates to a computer controlled imaging system involving a digital image processing and display system which has the ability to compose and construct a display scene from a library of images with sufficient processing speed to permit real-time or near real time analysis of the images by a human operator or a hardware/software equivalent thereof.
