1. A multi-camera image processing method, comprising: performing geometric alignment to produce a geometric output, wherein the geometric alignment comprises: estimating fish eye distortion correction parameters; performing initial perspective correction on related frame; running corner detection in the overlapping areas; locating the stronger corner; calculating brief descriptors for features and match feature point from two cameras using brief scores; performing checks and rejecting wrong feature matches; finding perspective matrices to minimize distance between matched features; and creating a geometric lookup table.
