The invention discloses a multi-view collaborative 3D
Gaussian splash optimization method and
system, and the method comprises the steps: constructing a multi-level heterogeneous
video memory pool, and dynamically dividing a
video memory in 3D
Gaussian reconstruction into a view exclusive
memory block and a global
shared memory pool; a mixed rendering-gradient pipeline is designed, and hardware-level pipeline parallelism in 3D
Gaussian reconstruction is realized through a double-buffer asynchronous switching
mechanism based on a
CUDA Warp-level parallel primitive fusion forward rendering and back propagation thread group; performing multi-view gradient joint optimization, screening an effective gradient path in 3D Gaussian reconstruction based on the
visibility mask matrix, and performing projection error weighted fusion on a multi-view gradient
tensor; and implementing a multi-
modal densification decision, generating a 3D Gaussian candidate splitting position in 3D Gaussian reconstruction through Monte Carlo sampling, calculating a joint optimization objective function by combining a multi-view projection residual error and a gradient contribution factor, and finally realizing 3D Gaussian reconstruction. According to the invention, high-precision and low-
delay large-scale scene real-time rendering and training can be realized.
