AI Technical Summary

Benefits of technology

This patented technology allows for create highly accurate 3D visual representations that preserve their shape even if they contain complex details or have uneven surfaces on them. It also ensurims the resulting display remains intact despite being cut into different shapes. Overall, this process improves efficiency and accuracy in generating 3D virtual reality experiences.

Problems solved by technology

This patented technical problem addressed by the current art relates to improving the quality of 3-dimensional (stereo) video or virtual reality (virtual reality), which requires accurate editing and processing for generating high-quality results without compromising their accuracy over large areas. Current techniques involve either manually adjustment or use complex algorithms to achieve these goals but they often require significant effort and may lead to unsatisfactory effects due to imperfections caused during the process itself.

Abstract

The embodiment of the invention discloses a three-dimensional image splicing method based on rectangular boundary preservation. The method comprises the following steps: S1, splicing globally optimized three-dimensional images; S2, extracting irregular boundaries of the three-dimensional panorama; S3, carrying out three-dimensional image splicing based on rectangular boundary constraint. Accordingto the method, a target rectangular boundary is defined according to features and parallax of a three-dimensional panorama, and three-dimensional image splicing with the rectangular boundary kept isachieved through global energy optimization.
