SYSTEMS AND METHODS FOR DEWARPING IMAGES
First Claim
1. A method comprising:
- receiving, by a processor, a first imagery from a first camera and a second imagery from a second camera, wherein the first imagery is warped, wherein the first imagery depicts a bottom of a vehicle, wherein the second imagery depicts an identifier of the vehicle;
dewarping, by the processor, the first imagery;
stitching, by the processor, the first imagery such that a first image is formed;
extracting, by the processor, a set of symbols from the second imagery, wherein the set of symbols corresponds to the identifier;
storing, by the processor, the first image and the set of symbols in a database such that the first image is associated with the set of symbols;
retrieving, by the processor, the first image from the database;
comparing, by the processor, a second image against the first image, wherein the second image depicts the bottom;
determining, by the processor, whether the second image satisfies a comparison threshold with respect to the first image; and
requesting, by the processor, a barrier to be opened responsive to the comparison threshold being satisfied such that the vehicle can pass the barrier.

Abstract
A computer-implemented method comprises: extracting a setting from a description file of a virtual pan-tilt-zoom (PTZ) camera used to capture an original image through a wide-angle lens; determining a first set of coordinates of a pixel of the original image for each cell of a sparse conversion map represented as a first look-up table, wherein the sparse conversion map corresponds to a sparse grid of pixels of an output image; determining, via interpolating the first set of coordinates, a second set of coordinates of a pixel of the original image for each cell of a full conversion map, wherein the second set of coordinates is represented as a second look-up table, wherein the full conversion map corresponds to a full grid of pixels of the output image; instructing a display to present the output image, wherein the original image is less rectilinear than the output image.

12. A system comprising:
a server configured to; receive a first imagery from a first camera and a second imagery from a second camera, wherein the first imagery is warped, wherein the first imagery depicts a bottom of a vehicle, wherein the second imagery depicts an identifier of the vehicle; dewarp the first imagery; stitch the first imagery such that a first image is formed; extract a set of symbols from the second imagery, wherein the set of symbols corresponds to the identifier; store the first image and the set of symbols in a database such that the first image is associated with the set of symbols; retrieve the first image from the database; compare a second image against the first image, wherein the second image depicts the bottom; determine whether the second image satisfies a comparison threshold with respect to the first image; and request a barrier to be opened responsive to the comparison threshold being satisfied such that the vehicle can pass the barrier. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
