Volumetric Calibration of Stereo Camera in Visual Servo Based Robot Control
International Journal of Advanced Robotic Systems, 2009 The primary objective of the paper is to propose a calibration method for a stereo camera used in a visual servo control for a robot manipulator. Specifically, projection matrix between the stereo camera and world coordinates is established using few ...

A Novel Solution for Camera Occlusion in Stereo Vision Technique
Advances in Mechanical Engineering, 2013 Stereo version is a well-known technique for obtaining depth and surface information of objects from images captured by two cameras. In general, this technique is limited by camera occlusion inherent to grooved or steep profiles in 3D shape measurements.

ACCURACY EVALUATION OF STEREO CAMERA SYSTEMS WITH GENERIC CAMERA MODELS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Abstract. In the last decades the consumer and industrial market for non-projective cameras has been growing notably. This has led to the development of camera description models other than the pinhole model and their employment in mostly homogeneous camera systems.
