Here, we focus on the calibration of a multiview shooting system designed for the production of three-dimensional content for auto-stereoscopic visualization. The particularities of this multiview camera are the coplanarity of the image sensors and the shift that each sensor represents with regard to the corresponding optical axis. For the calibration of such cameras, we propose an approach based on Faugéras and Toscani’s calibration method, which herein is extended to a multiview camera with parallel and decentered image sensors. First, the geometrical model of the shooting system is presented along with some industrial prototypes based on a geometrical analysis. Next, the development of the proposed calibration method is described. Last, some simulation results are presented, and some final concluding remarks about this research are then given.
This paper focuses on the calibration problem of a multi-view shooting system designed for the production of 3D content
for auto-stereoscopic visualization. The considered multi-view camera is characterized by coplanar and decentered image
sensors regarding to the corresponding optical axis. Based on the Faugéras and Toscani's calibration approach, a
calibration method is herein proposed for the case of multi-view camera with parallel and decentered image sensors. At
first, the geometrical model of the shooting system is recalled and some industrial prototypes with some shooting
simulations are presented. Next, the development of the proposed calibration method is detailed. Finally, some
simulation results are presented before ending with some conclusions about this work.
