Abstract:
A scene reconstruction method, apparatus, terminal device, and storage medium. The method includes: acquiring a first image set matching a to-be-reconstructed scene ( 11 ); extracting a characteristic region of an image in the first image set by using a characteristic extraction algorithm ( 12 ); performing recognition on the characteristic region to obtain a scene characteristic region in the image ( 13 ); and performing three-dimensional reconstruction on the to-be-reconstructed scene according to the scene characteristic region in the image, and rendering and generating the to-be-reconstructed scene ( 14 ). Some useless and unstable characteristic regions are filtered off, and the three-dimensional reconstruction on the to-be-reconstructed scene is performed only according to the scene characteristic region associated with the to-be-reconstructed scene, thereby improving the efficiency and accuracy of reconstruction.

Claim (Index 4):
The method according to  claim 1 , wherein after the performing three-dimensional reconstruction on the to-be-reconstructed scene according to the scene characteristic region in the image, and before the rendering and generating the to-be-reconstructed scene, the method further comprises:\n selecting images comprising more than a preset number of scene characteristic regions from the images as key frames; determining a neighboring relationship between the key frames according to a spatial relationship between scenes displayed in the key frames and times when the images are captured; and performing path planning for the to-be-reconstructed scene according to determined neighboring key frames.
