Claim 17:
18. The apparatus of claim 8, wherein the at least one processor is configured to execute the instructions to fuse the plurality of first continuous depth image sequences to establish the three-dimensional reconstruction model of the dynamic scene in the following manners:
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.
