AI Technical Summary

Technical Problem

Existing novel perspective synthesis methods are computationally expensive in real-time scenes and suffer from flickering artifacts, jagged artifacts, and occlusion leakage, making it difficult to achieve a balance between high rendering frame rates and high-quality fully differentiable joint optimization.

Method used

A depth-layered Gaussian-enhanced surface radiation field reconstruction method is adopted. It utilizes a hybrid representation of two-dimensional surface elements and three-dimensional Gaussian elements, and combines depth stripping rendering and three-dimensional Gaussian rendering with hardware depth testing and transmittance culling to achieve high-fidelity rendering without flicker artifacts.

Benefits of technology

At extremely high rendering rates (up to 470 frames per second at 1080p resolution), it generates high-fidelity, visually consistent, and anti-aliased images or videos, solving flickering artifacts and jagged edges, and improving rendering quality.

Abstract

The application discloses a kind of based on depth layering's Gauss enhanced panel radiation field reconstruction and drawing method.This method uses the hybrid structure of two-dimensional panel and three-dimensional Gauss;Rendering is divided into two stages: first depth stripping extraction panel is separated from three layers of depth, color and opacity map, and mixed to obtain the color and transmittance map of panel rendering;Second, three-dimensional Gauss is projected to screen, and according to its corresponding panel depth layer, the transmittance value is modulated color weight, and the invisible Gauss is removed using hardware depth test, finally, the final rendering color is obtained by mixing the rendering color of panel according to weight.In the reconstruction stage, the semi-transparent edge feature of panel makes the gradient of image loss back propagation to Gauss and panel, realizes completely differentiable joint optimization;And supplemented by panel image constraint, scale regularization and transmittance constraint loss function.The application effectively eliminates geometric edge sawtooth and Gauss flicker artifact, and can synthesize high-fidelity, consistent view angle new view image with high rendering rate.
