Abstract / Description:This paper presents an approach to intrinsic and extrinsic camera parameter
calibration from a series of photographs or from video. For the reliable and
accurate estimation of camera parameters it is common to use specially designed
calibration patterns. However, using a single pattern, a globally consistent
calibration is only possible from positions and viewing directions from where
this single pattern is visible. To overcome this problem, the presented
approach uses multiple coded patterns that can be distributed over a large
area. A connection graph representing visible patterns in multiple views is
generated, which is used to estimate globally consistent camera parameters for
the complete scene. The approach is evaluated on synthetic and real-world
ground truth examples. Furthermore, the approach is applied to calibrate the
stereo-cameras of a robotic head on a moving platform.
