ABSTRACT:
This invention relates to a method and apparatus for a system having a multisensor optical module with a large aperture angle, 180 degrees or more possible (360 degrees around), and an electronic interface which outputs two video or digital images of the scene. The first image is a high resolution representation of the entire field of view reconstructed from the partial views of each sensor. The second image is a high resolution representation of a selected part of the scene (window), the dimension and position of which can be interactively commanded through a communication port. The size and location of the window may be changed at every frame (typically every 1/30th of a second). The window field of view can cover the field of view of several adjacent sensors while the resulting image will remain continuous and undistorted. An arbitrary number of windows can be obtained with a unique optical sensor by adding electronic modules to the interface apparatus. The system is applicable, for example, in professional video and television, in industrial machine vision, in image processing, in surveillance systems, in teleguided and tele-operated systems and in many other fields.
