Eye Gaze Based 3D Triangulation for Robotic Bionic Eyes
Sensors, 2020 Three-dimensional (3D) triangulation based on active binocular vision has increasing amounts of applications in computer vision and robotics. An active binocular vision system with non-fixed cameras needs to calibrate the stereo extrinsic parameters ...

Robust visual servoing in 3d reaching tasks [PDF]
, 1996 This paper describes a novel approach to the problem of reaching an object in space under visual guidance. The approach is characterized by a great robustness to calibration errors, such that virtually no calibration is required.

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 ...

A Portable Active Binocular Robot Vision Architecture for Scene Exploration [PDF]
, 2016 We present a portable active binocular robot vision archi- tecture that integrates a number of visual behaviours. This vision archi- tecture inherits the abilities of vergence, localisation, recognition and si- multaneous identification of multiple ...

Deep Eyes: Binocular Depth-from-Focus on Focal Stack Pairs
, 2020 Human visual system relies on both binocular stereo cues and monocular focusness cues to gain effective 3D perception. In computer vision, the two problems are traditionally solved in separate tracks.

On the contribution of binocular disparity to the long-term memory for natural scenes [PDF]
, 2012 Binocular disparity is a fundamental dimension defining the input we receive from the visual world, along with luminance and chromaticity. In a memory task involving images of natural scenes we investigate whether binocular disparity enhances long-term ...

Research on DSO vision positioning technology based on binocular stereo panoramic vision system
Defence Technology, 2022 In the visual positioning of Unmanned Ground Vehicle (UGV), the visual odometer based on direct sparse method (DSO) has the advantages of small amount of calculation, high real-time performance and high robustness, so it is more widely used than the ...

Multifocal acceptance score to evaluate vision: MAS-2EV
Scientific Reports, 2021 We present a new metric (Multifocal Acceptance Score, MAS-2EV) to evaluate vision with presbyopic corrections. The MAS-2EV is based on a set of images representing natural visual scenes at day and night conditions projected in far and near displays, and ...
