Claim 16:
17. The method of claim 2, wherein fusing the plurality of first continuous depth image sequences to establish the three-dimensional reconstruction model of the dynamic scene comprises:
fusing the plurality of first continuous depth image sequences, determining a key frame reconstruction body according to a preset period, and performing, in each preset period, following operations:
determining a deformation parameter of a non-rigid deformation node in a current key frame reconstruction body, and updating a reconstruction model in the current key frame reconstruction body to a current data frame reconstruction body according to the deformation parameter, wherein the current data frame reconstruction body refers to a real-time reconstruction body at each moment;
extracting the three-dimensional reconstruction model of the dynamic scene from the current data frame reconstruction body; and
using the current data frame reconstruction body to replace the current key frame reconstruction body to act as a key frame reconstruction body in a next preset period.
