Virtual compound-eye camera system for acquiring three-dimensional scene of building satisfying time-space consistency and working method thereof

Abstract

The invention relates to the field of three-dimensional digital scene construction, provided are a virtual compound eye camera system for acquiring three-dimensional scene of a building satisfying spatio-temporal consistency and a working method thereof, the system includes a data acquisition module, positioning module and task assignment module, wherein the data acquisition module is composed ofall compound eye cameras facing the building object, and all compound eye cameras facing the building object are programmed according to a predetermined building acquisition grid, and the virtual group is formed into a complete and systematic compound eye system, which is called virtual compound eye; Virtual compound eye is composed of multiple compound eye cameras, which are programmed accordingto the acquisition grid of a given building, and are cooperated with each other to form a virtual compound eye. The virtual compound-eye camera system and the working method thereof can realize real-time shooting and real-time production with consistent time and space, and obtain more accurate and real dynamic three-dimensional virtual scene.

Description

technical field [0001] The invention relates to the field of three-dimensional digital scene construction, in particular to a virtual compound eye camera system and a working method thereof for collecting three-dimensional scenes (interior and exterior scenes) of buildings satisfying temporal and spatial consistency. Background technique [0002] Oblique projection shooting collects images from different angles and stitches them later to obtain a 3D virtual scene that conforms to human vision. At present, camera systems used for oblique projection shooting of 3D scenes mainly have five-lens, two-lens and single-lens lens structures. Among them, for five-lens and two-lens cameras, the spatial angle between the lenses is fixed, and the shooting scene is fixed by a single-axis gimbal; for a single-lens camera, a two-axis or three-axis gimbal drives the lens to align with the photographing target. [0003] In the acquisition application, a carrier such as a drone is generally u...

Problems solved by technology

[0007]2. At present, it mainly focuses on scenes other than architectural scenes, and there is no real 3D effect of integrating internal and external scenes.

[0008]3. There is no reasonable plan for the shooting point of the camera, and the shooting process of the camera mainly relies on artificial flight control, or a simple flight route according to the flight area through the flight control software Planning, resulting in a large amount of data redundancy or partial data loss

[0009]4. The subjectivity of the collectors in the collection operation is strong, it is difficult to establish a scientific, standardized, standardized and quantitative collection plan, it is difficult to maintain the stability of the collection quality, and it is difficult to Improve post-production efficiency
