Projection display optimization method, spectral imaging equipment and terminal equipment

Abstract

The invention relates to a projection display optimization method, spectral imaging equipment and terminal equipment. The projection display optimization method comprises the following steps: determining the type of a projection surface through a projection surface image under a non-irradiation condition and a uniform light irradiation condition; in response to a non-uniform projection surface type of the projection surface, determining a base light spectrum of a set image, the set image comprising a mosaic repeated image of a basic calibration image composed of a plurality of color blocks of any color with different brightness; projecting the set image to a target area of a projection surface, and acquiring a reflection spectrum of the set image reflected from the target area of the projection surface; calculating an ambient light spectrum and a reflection spectrum of a projection surface based on the reflection spectrums corresponding to the plurality of color blocks of the set image; and performing linear sampling and smoothing on the reflection image of the projection surface based on the ambient light spectrum and the reflection spectrum of the projection surface to obtain an optimized reflection image of the projection surface. Therefore, the projection effect of the projection equipment can be optimized.
