Title:
METHOD AND DEVICE FOR ADJUSTING THREE-DIMENSIONAL MODEL
Document Type and Number:
WIPO Patent Application WO/2017/177713
Kind Code:
A1
Abstract:
A method and device for adjusting a three-dimensional model. The method comprises: fusing a two-dimensional video corresponding to a target monitored area with a three-dimensional model to generate a mesh model (S101); determining whether each set plane in the mesh model is smooth according to the position of each reference plane in the stored three-dimensional model (S102); selecting, for each unsmooth target set plane, unsmooth points in the target set plane as mark points (S103); generating a virtual plane according to the mark points and the reference plane corresponding to the target set plane (S104); and adding the virtual plane to the three-dimensional model, and storing, for the two-dimensional video, the three-dimensional model to which the virtual plane is added (S105). By processing unsmooth planes, the fusion effect between a video and a three-dimensional model is improved. Since no modification to a three-dimensional scene model is required, labor costs and time costs for modifying the three-dimensional scene model are reduced.
