Document Type and Number:
WIPO Patent Application WO/2023/029458
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a correction method and apparatus, a device, and a storage medium. The correction method comprises: in the case of detecting a trigger operation for an automatic keystone correction function, obtaining a first correction parameter corresponding to a current user, then optimizing, according to the first correction parameter, an angle parameter obtained on the basis of three-dimensional reconstruction, and further performing automatic keystone correction on a first projected picture according to the optimized angle parameter. That is, according to the embodiments of the present application, after the automatic keystone correction function of a projection device is triggered, the angle parameter obtained by the three-dimensional reconstruction can be optimized using a correction parameter corresponding to the current user, such that the accuracy of an included angle of the projection device with respect to a carrier is improved, thus improving the correction effect of the first projected picture, and satisfying user requirements.
