Three-dimensional imaging and visualization using off-axially distributed image sensing.

This Letter presents an off-axially distributed image sensing (ODIS) system for three-dimensional (3D) imaging and visualization. The off-axially distributed sensing method provides both lateral and longitudinal perspectives for 3D scenes even though the sensor moves along a slanted, one-dimensional path. A 3D volume is generated from a set of recorded images by use of a computational algorithm based on ray backprojection. Preliminary experimental results are presented to illustrate the feasibility of the proposed system. To the best of our knowledge, this is the first report on 3D imaging and visualization using ODIS.
