Stereoscopic Photography is an art form as well as a science. Producing high quality 3D content needs plenty of vision and creativity while giving due consideration to the technical aspects involved. The control of technical parameters like interaxial distance and convergence angle of stereoscopic camera is essential to the production of aesthetic 3D content. However, it is difficult to determine...
In this paper, an efficient solution is proposed to the problem of 3D reconstruction from two uncalibrated views under Standard Vergence (SV) constraint. This solution consists of three core steps: firstly, set up the camera configuration according to SV constraint; secondly, estimate camera's focal length and relative pose between two views; lastly, reconstruct the scene optimally by minimizing reprojection...
To achieve a usable range measurement feature using a Vehicle-Mounted monocular camera for ADAS (Advantage Drive Assist System), a pitch angle estimation with high accuracy is required. We propose a method for estimating pitch angle with a non-occurrence of cumulative error, and the initial pitch angle can be estimated simultaneously with only a Vehicle-Mounted monocular camera. We use the Harris-corner...
As we known the vision system plays a very important role for people. Eye movements are an important part of human`s vision system. Scientists have studied fixational eye movements for many years, and the importance of fixational eye movements has been experimentally demonstrated. However, fixational eye movements have not been explained clearly because of the technical problems associated with experimentation...
This paper describes the relative pose estimation problems in a semi-calibrated case. It is well known that the fundamental matrix completely encapsulates the epipolar geometry between two perspective views. Through the parameterization of the fundamental matrix with the minimal parameters of pose and focal length, we formulate the problem as the minimum cost estimation problem with the aid of the...
Many binocular active tracking systems can track the target by vergence. However, the small vergence angle affects the vergence tracking in wide area. Furthermore, the scale variant problem will also disable the vergence tracking. To get a wide area security, we suggest installing a zoom control method to keep the target in the centre of the image instead of relying on vergence. We propose an active...
Scale variant is a big problem for wide area security and the target can only be tracked within limited area. To solve this problem, this paper is going to introduce a scale invariant algorithm of zoom control using depth which is calculated by stereo camera. We proposed a wide area tracking system consists of three tracking functions, including the first saccade, second saccade and smooth pursuit...
This study presents a robust face tracking method based on active stereo camera system. This system is a stereo vision system that can hold its gaze point on the face of the visual target during tracking it. When the system fixes its gaze point on the face exactly, the face can be discriminated from the background by binocular disparity. To keep the gaze point of the system on the face of a moving...
