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 θto θof the wide-angle lens, and acquiring ratios of adjacent FOVs βto βaccording to the n half FOVs θto θ; obtaining image heights IHs rto rcorresponding to the n half FOVs according to the n half FOVs θto θ; obtaining an IH relationship of adjacent half FOVs according to the ratios of adjacent FOVs βto βand the IHs rto rcorresponding 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.
