Document Type and Number:
WIPO Patent Application WO/2018/102990
Kind Code:
A1
Abstract:
System and method can rectify a wide-angle image captured using a wide-angle lens. The system can obtain a projection model for the wide-angle lens, wherein the projection model corresponds the wide-angle image with a plurality of target image portions in a target image. Furthermore, the system can determine, based on the projection model, a plurality of reference pixels in the wide-angle image for a target pixel in the plurality of target image portions. Then, the system can calculate one or more pixel values for said target pixel based on the plurality of reference pixels in the wide-angle image.
