This paper presents work towards the development of an accurate binocular eye tracking system for 3DTV-Applications. For that to happen, virtual modeling of eye tracking data is prepared. The model is based on defined suitable parameters considering a wide range of complex influencing factors from the distinctive binocular use case. This work in progress presentation is concluded by results of an...
Color discrepancies between the left and right images from a stereoscopic camera cause many problems, including a reduction in the three-dimensional effect and increased visual fatigue. Thus, color matching of stereoscopic images is very important for three-dimensional display systems. Therefore, this paper proposes simultaneous color matching based on image decomposition. The stereoscopic images...
Advances in robotic surgery especially in minimally-invasive surgery (MIS) has increased the need for translating computer-vision algorithms in endoscopic imagery to support surgical decisions. While methods for stereo reconstruction have been extensively investigated for man-made environments, such an extensive and detailed study on the pros and cons of stereo reconstruction for endoscopic images...
Binocular stereo matching is always hot and difficult issues in the machine vision, the advantages and disadvantages of feature stereo matching method is analyzed in the paper, and an improved feature stereo matching method is proposed. First, using the SIFT feature extracting algorithm to extract basic feature points, utilizing these feature points as the starting points, and then finding the similar...
This paper presents an efficient approach to estimate temporal synchronization distortions in 3D sequences, based on measuring motion consistencies of object feature points in depth planes. Errors in post-processing steps or exposure setups of stereo cameras can cause temporal asynchronization between stereoscopic channels. This kind of 3D artifacts lead to poor 3D experience for viewers. Due to the...
The objective of this paper is to reconstruct three-dimensional scenes from stereo images. In this paper, the single-lens stereovision system using biprism is employed to capture image pairs. Then, we propose a geometry-based approach to solve stereo rectification problem based on this system. It does not require complex calibration at all and also can obtain accurate extrinsic matrix. Then we propose...
The world's first regular 3D broadcasting was successfully launched by SBS(Seoul Broadcasting System), Korea. Moreover, the amount of 3D videos which were produced on HD / DCI format has increased. 3D videos have already been captured with 4K UHD(3840×2160) resolution. As the displays for 3D UHD display begin to become general, 3D UHD is going to be the standard for broadcasting and commercial films...
In this paper, we introduce a Natural Feature Tracking (NFT) system capable of running at real-time on limited powered devices. Combining current vision techniques with stereoscopic cameras has benefits that reduce processing expense and increase the suitability of the resultant data. The novel use of stereoscopic imaging centered within a single device allows for extraction of features from dynamic...
One of the drawbacks of current 3DTV systems are the glasses required to separate the 3D views. This problem can be solved by using autostereoscopic 3D displays, which generates a 3D scene from different viewpoints. These viewpoints are synthesized in the display based on depth information of the scene. However, currently no depth information is available for stereoscopic video. Therefore, depth estimation...
The Stereo Camera (STC) of the SIMBIO-SYS imaging suite of the BepiColombo ESA mission to Mercury is based on an innovative and compact design in which the light, independently collected by two optical channels at ±20° separation with respect to nadir, falls on a common bidimensional detector. STC adopts a novel stereo acquisition mode, based on the push-frame concept, never used before on a space...
This paper introduces two unusual optical range finders and compares them to each other and to stereo and optical flow based range finding. The axially displaced sensor uses to optical flow sensitive cameras at different distances to the scene. The paraxial array sensor uses an array of light sensitive elements that can be optically or mechanically rotated to provide a range measurement. Both sensors...
Stereoscopic tabletops offer unique visualization capabilities, enabling users to perceive virtual objects as if they were lying above the surface. While allowing virtual objects to coexist with user actions in the physical world, interaction with these virtual objects above the surface presents interesting challenges. In this paper, we aim to understand which approaches to 3D virtual object manipulations...
This paper describes an integrated system for the real time acquisition, streaming, and display of stereoscopic 3D video in mixed reality environments. These mixed reality environments combine real-time stereoscopic video with rendered 3D environments composed of sampled and modeled 3D data from actual landscapes or structures. While live video itself is an important part of exploration, reconnaissance,...
3D cinema is heading towards self-sufficient maturity both technically and aesthetically. In this paper, I will undertake a comparative analysis of the distinctions between 3D and 2D cinema based on a correlation between techniques of production and perceptual physiologies. Moreover, with reference to Siegfried Kracauer's classic remark about cinematic ontology that “the nature of film is the redemption...
Stereoscopic 3D (S3D) display is beneficial for educational purposes, although visual fatigue remains an issue for practical use. To avoid this, we have introduced an intermittent S3D exposure method. In order to clarify detailed effects of pictorial cues in 2D and S3D, this study introduces a rotating lines perception test, in which the random rotational motion of two lines provides pictorial cues...
In this paper, we present a depth reconstruction method for lenslet-based plenoptic cameras. Previous work in depth reconstruction from light field data was focused on synthetic or non lenslet-based plenoptic cameras. Lenslet-based plenoptic camera uses microlenses to obtain the 4D light field and results in a large non-uniformity across the sensor. A novel correction was applied to shading due to...
In this paper, we propose the development of a system for generating disparity maps using rectified images, one technique that is booming in depth perception systems in computer vision. For this reason, in this project, is made a brief explanation process associated with mating techniques for stereo vision. For this project, we explore correlation algorithms, such as sum of absolute differences and...
Recently, stereoscopic video systems are studied in the context of many new applications. This paper addresses the question how the road traffic surveillance may benefit from stereoscopic video analysis. In particular, we propose a novel method for estimating vehicle dimensions using stereoscopic video analysis. This method is based on active appearance model (AAM), a technique already used, e.g....
In the paper vehicle length estimation based on stereoscopic video analysis is considered. The accuracy of the parameters of the stereoscopic video acquisition system influence accuracy of the estimated vehicle length. The respective analysis is provided in the paper. The main result is the formula for estimating the accuracy of the vehicle length measurement.
Quality assessment on emerging stereoscopic 3D media is still in an early stage when compared to 2D image/video quality assessment. New characteristics (e.g. specific artifact perception, visual strain, perceived depth) and various requisite factors in stereoscopic systems (e.g. system-introduced crosstalk, screen size, viewing position, scene content, camera baseline) should be taken into account...
