Image construction method and device, electronic equipment and storage medium

Abstract

The invention relates to an image construction method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a target projection matrix when image acquisition is performed on a target scene at a target observation point; for each target pixel point in the to-be-constructed image, determining target light corresponding to the target pixel point; projecting the target light by adopting the target projection matrix to obtain projection information of the target light on a preset sampling surface, wherein the preset sampling surface comprises a plurality of preset image sampling points for performing image acquisition on the target scene; determining the color of the target pixel point based on the projection information and the plurality of preset image sampling points; and constructing a target image corresponding to the target observation point according to the color of each target pixel point in the to-be-constructed image. The image construction method and device can solve the problems that the image rendering result loses authenticity and a large amount of storage space is consumed in the image construction process.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image construction method, device, electronic equipment, and storage medium. Background technique [0002] In various fields such as e-commerce, virtual exhibition, interactive experience, etc., it is necessary to describe the target scene from multiple angles, so that the user can present the image of the target scene corresponding to the corresponding angle when browsing in real time. [0003] In related technologies, there are mainly two methods to describe the target scene from multiple angles. One method is to use the 3D mesh model (including through the triangular patch position, normal direction, texture data) and related information (such as lighting, environment texture, etc.) etc.) to describe the entire scene, when browsing in real time, place the virtual camera at the observation point, and then render the 3D scene through the standard renderi...
