Image processing system comprising fixed cameras and a system simulating a moving camera

Abstract

Abstract Digital image processing system with: - a system of n real fixed cameras (C1,...Ci, Cj,... Cn), the individual fields of view of which merge together for taking a view of a panoramic scene, - an image construction system (GVVB) simulating a moving camera (Cv) called virtual camera, which continuously scans the panoramic scene in order to furnish an arbitrary sub-image thereof, called target image (lv), which is digital and constructed from adjacent source images (I1,...Ii, Ij,... In) from the real cameras, - a luminance equalisation system, including modules (LUT.A, LUT.B) which apply correction laws (Gi, Gj) respectively to the sets (R and F(R)) of the corresponding luminance levels in the parts (Ivi, Ivj) of a digital target image (Iv) which is constructed from two adjacent digital source images (Ii, Ij), in order to equalise these levels according to the relation Gi(R) = Gj[F(R)]. Application: monitoring devices, panoramic viewing devices for moving vehicles. <IMAGE>
