Abstract
Disclosed in the present invention is an indoor scene virtual roaming method based on reflection decomposition, the method includes: firstly, by means of three-dimensional reconstruction, obtaining a rough global triangular mesh model projection as an initial depth map, aligning depth edges to color edges, and converting the aligned depth map into a simplified triangular mesh; checking planes in the global triangular mesh model, and if a certain plane is a reflection plane, constructing a double-layer expression in a reflection area for each picture in which the reflection plane is visible, so as to correctly render the reflection effect on an object surface; and giving a virtual viewport, using neighborhood pictures and the triangular mesh to draw a picture of the virtual viewport, and for the reflection area, using foreground and background pictures and foreground and background triangular meshes to perform drawing.
