Environment three-dimensional appearance scene reconstruction method

The invention relates to an environment three-dimensional appearance scene reconstruction method, which comprises the following steps of: performing grid division on a large scene into a plurality of equal parts, determining a grid center point, and determining a plurality of observation points around the grid center point; respectively completing scene reconstruction of the three-dimensional appearance of each observation point; determining the weight of each observation point based on the distance between each observation point and the grid center point, and completing the final reconstruction of the three-dimensional appearance scene based on the weight and the reconstructed three-dimensional appearance scene at each observation point. According to the method, a representation method of a three-dimensional scene can be quickly established through an instantaneous NeRF technology of Hash coding, the storage space of a large amount of three-dimensional data is saved by storing three-dimensional information i
