Title:
THREE-DIMENSIONAL SCENE RECONSTRUCTION METHOD AND APPARATUS, DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/088071
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to the technical field of computer vision, and provide a three-dimensional scene reconstruction method and apparatus, a device and a storage medium. The method comprises: determining a terrain layer according to j target images; performing semantic recognition and pixel depth estimation on at least one target image to obtain semantic objects; using a semantic object which meets a first preset condition as a first semantic object, and determining a vector contour of the first semantic object in the terrain layer according to camera parameters; using a semantic object which meets a second preset condition as a second semantic object, and determining a modeling position of the second semantic object in the terrain layer according to the camera parameters; and performing three-dimensional reconstruction according to the vector contour, the modeling position and the terrain layer to obtain a three-dimensional reconstruction model of an outdoor scene. The terrain layer, the first semantic object and the second semantic object are automatically generated, and the vector contour of the first semantic object in the terrain layer and the modeling position of the second semantic object in the terrain layer are automatically extracted, so that the three-dimensional reconstruction efficiency of the outdoor scene is increased.
