Abstract:
1. A computer-implemented method for determining an egomotion parameter using an egomotion estimation system comprising: obtaining a first image frame and a second image frame; selecting a first portion of the first image frame to obtain a first sub-image that is formed from the first image frame, and selecting a second portion of the second image frame to obtain a second sub-image that is formed from the second image frame; performing a transformation on the first sub-image and the second sub-image to respectively obtain a first perspective image and a second perspective image; iteratively adjusting the second perspective image to obtain a plurality of adjusted perspective images; determining a plurality of difference values respectively corresponding to a respective difference between the first perspective image and the plurality of adjusted perspective images; and determining a translation vector for an egomotion parameter, wherein the translation vector corresponds to one of the difference values in the plurality of difference values.
