DLT-Like Calibration of Central Catadioptric Cameras
In this study, we present a calibration technique that is valid for all single-viewpoint catadioptric cameras. We are able to represent the projection of 3D points on a catadioptric image linearly with a 6×10 projection matrix, which uses lifted coordinates for image and 3D points. This projection matrix can be computed with enough number of 3D2D correspondences (minimum 20 points distributed i...
متن کاملDirect Self-Calibration of Central Catadioptric Omnidirectional Cameras
Calibrating a camera means determining the geometric properties of the imaging process, i.e., the transformation that maps a three-dimensional point, expressed with respect to a reference frame, onto its two-dimensional image whose coordinates are expressed in pixel units. This process is required when recovering 3D information. More precisely, we have to know the translation and rotation of th...
متن کاملSelf-calibration of hybrid central catadioptric and perspective cameras
Hybrid central catadioptric and perspective cameras are desired in practice, because the hybrid camera system can capture large field of view as well as high-resolution images. However, the calibration of the system is challenging due to heavy distortions in catadioptric cameras. In addition, previous calibration methods are only suitable for the camera system consisting of perspective cameras ...
متن کاملVisual servoing of mobile robots using non-central catadioptric cameras
This paper presents novel contributions on image-based control of a mobile robot using a general catadioptric camera model. A catadioptric camera is usually made up by a combination of a conventional camera and a curved mirror resulting on an omnidirectional sensor capable of providing 360o panoramic views of a scene. Modeling such cameras has been subject of significant research interest in th...
متن کاملNon-Central Catadioptric Cameras Pose Estimation using 3D Lines
In this article we purpose a novel method for planar pose estimation of mobile robots. This method is based on an analytic solution (which we derived) for the projection of 3D straight lines, onto the mirror of Non-Central Catadioptric Cameras (NCCS). The resulting solution is rewritten as a function of the rotation and translation parameters, which is then used as an error function for a set o...
