Document Type and Number:
WIPO Patent Application WO/2022/166868
Kind Code:
A1
Abstract:
A walkthrough view generation method, apparatus and device, and a storage medium. The method comprises: acquiring an initial three-dimensional model and a repaired three-dimensional model corresponding to the initial three-dimensional model in the same spatial region, wherein the repaired three-dimensional model is obtained after spatial information in the initial three-dimensional model is repaired; respectively determining a first intersection point set of walkthrough light corresponding to the current walkthrough parameter and the initial three-dimensional model, and a second intersection point set of the walkthrough light and the repaired three-dimensional model, wherein the current walkthrough parameter comprises a walkthrough position and a walkthrough viewing angle after a movement; and fusing the initial three-dimensional model and the repaired three-dimensional model according to the depth difference between corresponding intersection points in the first intersection point set and the second intersection point set, and rendering a fusion result to obtain the current walkthrough view.
