The geometrical calibration of a high-definition camera rig is an important step for 3D film making and computer vision applications. Due to the large amount of image data in high-definition, maintaining execution speeds appropriate for on-set, on-line adjustment procedures is one of the biggest challenges for machine vision based calibration methods. Our(More)
Over the last decade, advances in technology have made stereoscopic 3D (S3D) displays widely available with an ever-expanding variety of technologies, dimensions, resolution, optimal viewing angle and image quality. Of these, one of the most variable and unpredictable factors influencing the observer's S3D experience is the display size, which ranges from(More)
A primary concern when making stereoscopic 3D (S3D) movies is to promote an effective and comfortable S3D experience for the audience when displayed on the screen. The amount of depth produced on-screen can be controlled using a variety of parameters. Many of these are lighting related such as lighting architecture and technology. Others are optical or(More)
Résumé. Nous présentons dans cet article le système Skin3D qui implémente tous les composants matériels et logiciels nécessaires pour extraire des informations dans des images 3D de peau. Il s’agit à la fois du matériel d’éclairage et d’acquisition à base d’appareils photographiques stéréoscopiques, d’une méthode de calibration de caméras utilisant les(More)
Stereoscopic 3D film production has increased the need for efficient and robust camera calibration and tracking. Many of these tasks involve making planar correspondence and thus accurate fast homography estimation is essential. However, homography estimation may fail with distorted images since the planar projected corners may be distorted far away from(More)
