US 9,071,819 B2 · System and method for providing temporal-spatial registration of images

Abstract

A video imaging system for use with or in a mobile video capturing system (e.g., an airplane or UAV). A multi-camera rig containing a number of cameras (e.g., 4) receives a series of mini-frames (e.g., from respective field steerable mirrors (FSMs)). The mini-frames received by the cameras are supplied to (1) an image registration system that calibrates the system by registering relationships corresponding to the cameras and/or (2) an image processor that processes the mini-frames in real-time to produce a video signal. The cameras can be infra-red (IR) cameras or other electro-optical cameras. By creating a rigid model of the relationships between the mini-frames of the plural cameras, real-time video stitching can be accelerated by reusing the movement relationship of a first mini-frame of a first camera on corresponding mini-frames of the other cameras in the system.

Claims24

Dependent claims

A video registration system, comprising:

circuitry for receiving at least first and second mini-frames from a first camera of plural fixedly interconnected cameras;
circuitry for creating a first extended mini-frame for the first camera of the plural fixedly interconnected cameras from at least the first and second mini-frames;
circuitry for receiving a third mini-frame from a second camera of the plural fixedly interconnected cameras;
and
circuitry for registering the first extended mini-frame and at least the third mini-frame to determine a first registration relationship between the first and second cameras.
