Analysis and design of circular line-scan imaging for 3D scene visualization and reconstruction

This paper addresses recent developments of circular line-scan imaging system for applications of 3D scene visualization and/or reconstruction. Such an imaging system is characterized by rotating linear sensors capturing one image column at a time respectively. This allows for accurate mappings onto a cylindrical image surface and very high image resolutions paid by motion distortions in dynamic scenes. These images can be used, for example, for stereo visualization and 3D reconstruction in the VR applications where extremely high image resolution is of benefit (for static scenes). The paper elaborates the basic geometry, the geometric analysis, and the design and control of imaging parameters to ensure high-quality 3D data acquisition.
