A method and related device for automatic lighting of indoor scenes

Abstract

The invention discloses an indoor scene automatic light distribution method and a related device. The method comprises the steps of carrying out the convex decomposition of a target scene space, and obtaining a plurality of convex polygonal regions; traversing all the lamps in the target scene space, and adding the lamps into a lamp list of the corresponding convex polygon area according to the area where the lamps are located; when the lamp list is empty, determining the lamp distribution type, the lamp distribution number, the lamp distribution intensity and the lamp distribution position ofthe convex polygon area on the basis of the calculated maximum inscribed rectangle and a preset lamp distribution rule; when the lamp list is not empty, calculating gain values of all lamps in the convex polygon area based on the calculated illumination intensity required by the convex polygon area and the distributed light source intensity; and performing gain adjustment on all the lamps in theconvex polygon area based on the gain value. The technical problem that the existing automatic light distribution method performs non-differential layout on the light of the whole space, does not consider the situation that the lamps exist in the scene, and has relatively large deviation with the actual light effect is solved.

Description

technical field [0001] The present application relates to the technical field of interior design, in particular to an automatic lighting method for an indoor scene and related devices. Background technique [0002] Interior scene design renderings are an important tool for designers to communicate with customers. The quality of design renderings directly affects customers' approval of design schemes and products. A good design rendering is inseparable from the careful design of the scene by the designer. Reasonable lighting layout and lighting effects are very important for the scene design. [0003] In the traditional lighting process of indoor scenes, the designer bases on the layout of lighting fixtures and lighting conditions in the design scheme, and according to the needs of the scheme performance, combined with the designer's experience to determine the lighting type, position, size, color and so on in the design scene. Temperature and other parameters are set, and t...
