Abstract

The invention discloses a projection image correction method and a correction device. The correction method includes: acquiring depth information of a projection area; determining a projection reference plane according to the depth information; and determining deformation of the projection area based on the projection reference plane position; perform correction processing on the image to be projected according to the deformed position. The technical scheme of the invention can effectively correct the distorted display screen and improve the imaging quality.

Description

technical field [0001] The present invention relates to the technical field of image display, in particular to a projection image correction method and correction device. Background technique [0002] With the development of projection display technology, projectors have gradually entered people's daily home life from office supplies. Through the projector, the user can display the displayed content at any time. However, the projector has high requirements on the flatness of the projection display plane. If the projection display plane has a concave or convex position, the light will be superimposed or scattered at this position, and the projection display screen will be distorted and deformed, resulting in poor image quality. [0003] The above content is only used to assist in understanding the technical solution of the present application, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] Based on this, aiming at the...
