Selective rendering for efficient ray traced stereoscopic images [PDF]

, 2009
Depth-related visual effects are a key feature of many virtual environments. In stereo-based systems, the depth effect can be produced by delivering frames of disparate image pairs, while in monocular environments, the viewer has to extract this depth ...

Neuromorphic Stereo Vision: A Survey of Bio-Inspired Sensors and Algorithms

Frontiers in Neurorobotics, 2019
Any visual sensor, whether artificial or biological, maps the 3D-world on a 2D-representation. The missing dimension is depth and most species use stereo vision to recover it.

3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

Advanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.

Modeling the measurement accuracy for binocular stereo vision system

Optics Express
Binocular stereo vision technology is widely used in the 3D measurements of aerospace, the automotive industry, and in other fields. However, its measurement accuracy is limited by many error factors and is difficult to improve. This paper presents a modeling method for the measurement accuracy of binocular stereo vision systems, providing a ...

FLSea: Underwater Visual–Inertial and Stereovision Forward‐Looking Data Sets

Journal of Field Robotics, EarlyView.
ABSTRACT Visibility underwater is challenging and degrades as the distance between the subject and the camera increases. That is why forward‐looking underwater computer vision tasks are difficult. We have collected underwater forward‐looking stereovision and visual–inertial image sets using two underwater imaging platforms, a stereo camera rig, and an ...
