Background:

Traditional 3D reconstruction often requires complex multi-camera setups.
Achieving accurate 3D reconstruction relies on robust pose estimation and sufficient visual constraints.

Purpose of the Study:

To introduce a novel visual 3D reconstruction system using a virtual multi-ocular system (VMOS).
To demonstrate a concise hardware configuration for high-performance 3D reconstruction.

Main Methods:

Developed a system with a two-axis galvanometer scanner and a camera to create a VMOS.
Implemented a method for calibrating intrinsic and extrinsic parameters of the VMOS.
Investigated the system's applicability for 3D reconstruction and object pose estimation.

Main Results:

The VMOS enables rapid adjustment of camera boresight for capturing objects from multiple perspectives.
The VMOS provides stronger constraints for object pose estimation compared to standard cameras.
Experimental results show competitive 3D reconstruction performance against conventional stereovision systems.

Conclusions:

The proposed VMOS offers a more concise hardware solution for 3D reconstruction.
The system demonstrates effective 3D reconstruction capabilities with enhanced pose estimation.
This approach presents a viable alternative to conventional stereovision systems.
