Shielding evaluation method, device, equipment and system based on mutual view angle, and medium

Abstract

The invention discloses a shielding evaluation method, device, equipment and system based on a mutual view angle, and a medium. The method comprises the following steps: acquiring first imaging dataacquired by at least one top depth camera at a top view angle of a target scene, and acquiring second imaging data acquired by a light field camera array at a main view angle of the target scene; obtaining a three-dimensional coordinate set under a world coordinate system for the head of the person in a plurality of regions in the target scene; modeling each personnel coordinate to a focal plane where the face of the target personnel sits according to the three-dimensional coordinate set to obtain a personnel focal plane coordinate set; and according to at least one color sensor in the light field camera array, evaluating the shielding condition of the target person under the visual angle of any one or more color sensors, and obtaining a shielding degree evaluation set for the target person so as to select an optimal visual angle. According to the invention, the optimal visual angle can be selected to render the light field of the shielded position, and the optimal face information isobtained.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an occlusion evaluation method, device, device, system and medium based on a mutual perspective. Background technique [0002] As an electromagnetic field distributed in space, light has various properties such as amplitude, phase, and wavelength, and helps humans perceive the brightness, position, and color of objects. However, traditional optical imaging intelligently captures the projected intensity of light radiation on a two-dimensional plane, while losing the three-dimensional shape data of the target. Light field data acquisition is to obtain the complete distribution of light radiation, and calculate the required image through data processing methods such as transformation and integration. Light field imaging refers to the process of collecting light field and processing the light field into an image. As a computational imaging technology, light field i...
