Patent ID: 10748258

Abstract:
The present disclosure provides a method, a device and a system for correcting distortion of a wide-angle lens. The method includes: acquiring n half field of views FOVs θ1 to θn of the wide-angle lens, and acquiring ratios of adjacent FOVs β1 to β(n-1) according to the n half FOVs θ1 to θn; obtaining image heights IHs r1 to rn corresponding to the n half FOVs according to the n half FOVs θ1 to θn; obtaining an IH relationship of adjacent half FOVs according to the ratios of adjacent FOVs β1 to β(n-1) and the IHs r1 to rn corresponding to the n half FOVs, and obtaining the IH of each half FOV through recurrence calculation according to an IH corresponding to a maximum FOV and the IH relationship of adjacent half FOVs; and correcting distortion of the wide-angle lens across FOVs according to the IH of each half FOV.
