3-D modeling Using a Monocular Plenoptic Camera


A plenoptic camera is a passive, off-the-shelf industrial camera that has been reengineered to measure the focused depth of image projections within the camera. Using this information and with the help of a calibrated camera model, it is possible to infer the depth of the scene in front of the camera. Contrary to widespread depth cameras like the Kinect or time-of-flight cameras, plenoptic cameras only require one lens aperture and they do not need to actively emit any radiation unto the environment.

Recently we published a method to metrically calibrate a plenoptic camera in a previously unattained level of accuracy. We now have the opportunity to be the first to model an object in 3-D using a single plenoptic camera in an accurate, metric way. To that end, synthetic brightness images and metric depth images are available. For instance, the brightness images can be used for up-to-scale 3-D modeling, using bundle adjustment and dense structure from motion (e.g. using our institute's SGM implementation). After that, the metric depth images can be used to optimally apply the correct metric scale to the reconstructed model.
