A biprism-stereo camera system [PDF]
Proceedings. 1999 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (Cat. No PR00149), 2003 In this paper we propose a novel and practical stereo camera system that uses only one camera and a biprism placed in front of the camera. The equivalent of a stereo pair of images is formed as the left and right halves of a single CCD image using a biprism.

Cameras for stereo panoramic imaging [PDF]
Proceedings IEEE Conference on Computer Vision and Pattern Recognition. CVPR 2000 (Cat. No.PR00662), 2002 A panorama for visual stereo consists of a pair of panoramic images, where one panorama is for the left eye, and another panorama is for the right eye. A panoramic stereo pair provides a stereo sensation lip to a full 360 degrees. A stereo panorama cannot be photographed by two omnidirectional cameras from two viewpoints.

Photometric Stereo with Twin-Fisheye Cameras [PDF]
2020 25th International Conference on Pattern Recognition (ICPR), 2021 In this paper, we introduce and solve for the first time, the photometric stereo problem for low-cost 360-degree cameras. In particular, we present a spherical image irradiance equation which is adapted to twin-fisheye cameras, and an original algorithm for the estimation of light directions based on the specular highlights observed on mirror balls ...

Illumination and camera invariant stereo matching [PDF]
2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008 Color information can be used as a basic and crucial cue for finding correspondence in a stereo matching algorithm. In a real scene, however, image colors are affected by various geometric and radiometric factors. For this reason, the raw color recorded by a camera is not a reliable cue, and the color consistency assumption is no longer valid between ...

Photometric stereo with central panoramic cameras
Computer Vision and Image Understanding, 2020 Abstract In this paper, we introduce and rigorously solve for the first time the photometric stereo problem for central panoramic systems. In particular, by leveraging the unified camera model, we present a new spherical image irradiance equation and analyze its mathematical properties in detail.

Obstacle Avoidance Using Stereo Camera
CoRR, 2017 In this paper we present a novel method for obstacle avoidance using the stereo camera. The conventional obstacle avoidance methods and their limitations are discussed. A new algorithm is developed for the real-time obstacle avoidance which responds faster to unexpected obstacles.
