The invention provides a three-dimensional scene construction method, a three-dimensional scene construction device, a computer storage medium and electronic equipment, and relates to the technical field of computer vision. The three-dimensional scene construction method comprises the following steps: acquiring a plurality of acquired scene images; dividing the scene images into at least two imagegroups according to a matching relationship between the scene images; adding a scene image adjacent to the image group to the at least one image group so as to expand the at least one image group; respectively carrying out three-dimensional reconstruction processing on the scene images in each image group to obtain a local scene model corresponding to each image group; and combining the local scene models to obtain a complete three-dimensional scene model. According to the method, the problem that the image acquisition process is complex and tedious can be solved, the image acquisition efficiency is improved, the image acquisition cost is reduced, the correlation degree between local scene models can be improved, and the precision of the reconstructed model is ensured.
Description
technical field [0001] The present disclosure relates to the technical field of computer vision, and in particular to a three-dimensional scene construction method, a three-dimensional scene construction device, a computer storage medium and electronic equipment. Background technique [0002] Three-dimensional reconstruction refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects. It is the basis for processing, operating and analyzing its properties in a computer environment, and it is also a key technology for establishing a virtual reality that expresses the objective world in a computer. [0003] In related technologies, before performing 3D reconstruction of a large scene, it is generally necessary to provide professional training to the image collectors to ensure that the adjacent sub-regions of the collected images are guaranteed to contain the same control points at the same time, and then th...
