Calibration of Hand-Held Camera Sequences for Plenoptic Modeling

In this contribution we focus on the calibration of very long image sequences from a hand-held camera that samples the viewing sphere of a scene. View sphere sampling is important for plenoptic (image-based) modeling that captures the appearance of a scene by storing images from all possible directions. The plenoptic approach is appealing since it allows in principle fast scene rendering of scenes with complex geometry and surface reflections, without the need for an explicit geometrical scene model. However the acquired images have to be calibrated, and current approaches mostly use pre-calibrated acquisition systems. This limits the generality of the approach. We propose a way out by using an uncalibrated handheld camera only. The image sequence is acquired by simply waving the camera around the scene objects, creating a zigzag scan path over the viewing sphere. We extend the sequential camera tracking of an existing structure-frommotion approach to the calibration of a mesh of view...
