Problems solved by technology

The shadows in the diffuse reflection map include shadows caused by direct light and shadows caused by ambient light. Currently, tools such as Agisoft Texture Delighting are usually used to remove shadows caused by direct light, and tools such as Unity De-Lightingtool are used to remove indirect light. The shadows generated by lighting, but these de-lighting and shadowing schemes have problems such as loss of texture details, hue changes, color overflow and color blocks, which lead to unrealistic model effects and cannot be applied to any lighting. Conditional scenario, poor user experience

Abstract

The invention provides an image processing method and device, a computer storage medium and electronic equipment, and relates to the field of image processing. The method comprises the steps of acquiring a diffuse reflection map, and acquiring shadow streak elements in a shadow area in the diffuse reflection map; querying in an average color lookup table according to the space coordinate information of the shadow texel, and determining an average brightness difference corresponding to the shadow texel according to a query result; and determining restored color information according to the average brightness difference and the color information corresponding to the shadow texel, and restoring the color information of the shadow texel according to the restored color information. According tothe invention, shadows in the diffuse reflection map can be effectively removed, so that the model can be used in a scene under any illumination condition.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to an image processing method, an image processing device, a computer-readable storage medium, and electronic equipment. Background technique [0002] In art design, 3D model modeling technology based on photogrammetry is usually used for modeling. The 3D model modeling technology based on photogrammetry uses multiple photos for 3D modeling, and uses multiple photos The pixel color information is used to restore the diffuse color information of the object, so the color map of the generated model must have the shadow in the original photo. [0003] In order to use the resulting model in scenes with arbitrary lighting conditions, shadows in the diffuse map must be removed while preserving as much of the original color information as possible. The shadows in the diffuse reflection map include shadows caused by direct light and shadows caused by ambient light. Cu...
