Title:
GENERAL LAYOUT-BASED MULTI-SITE MULTI-VIEW VIDEO FUSION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/040863
Kind Code:
A1
Abstract:
The present invention relates to the fields of digital construction supervision and the like. Disclosed are a general layout-based multi-site multi-view video fusion method and system. The method comprises: monitoring full-coverage site planning and device deployment based on an engineering project general layout; monitoring region division based on building space height layers; multi-view video fusion in respect of local monitoring regions; local fused video key region extraction; regional padding and fusion based on the engineering project general layout as a base layout; picture blind spot filling or deduplication by quick increase or decrease of cameras; and color equalization and splicing seam removal fusion optimization processing for the edges of videos of a plurality of regions. The present invention effectively solves the problems of dependence of multi-site multi-view video fusion on a three-dimensional model and the complexity of frequently updating the three-dimensional model due to a complex and changeable construction site environment, achieves synchronous supervision, dispatching and commanding for a plurality of construction work surfaces, pavements, yards and the like of an administered project, improves the supervision capability and efficiency, and has high practicability and universality.
