Abstract: An imagery axle turning method for stereo vision and an apparatus thereof. The method turns an imagery axle of a stereo vision apparatus to capture images, and constructs a 3D image from the captured 2D images. The imagery axle turning method is realized by rotating the imagery axles of the first lens unit and second lens unit to an angle ?, so as to have different aspect ratios for the first image and second image. Thereby, the 3D image formed from the stereo vision reconstruction steps can achieve a user's expectation of capturing images with an appropriate aspect ratio. This invention also provides specific stereo vision apparatus corresponding to various applications by the imagery axle turning method.

Abstract: A monitoring system for generating a three-dimensional (3D) image, the system including: a plurality of monitoring cameras which are arranged to capture respective images of an area such that a portion of an angle of view of one monitoring camera overlaps a portion of an angle of view of another monitoring camera; and a controller which crops a plurality of overlapped images, each of which is an image of the overlapped portion, from among the respective images captured by the plurality of monitoring cameras, and generates a 3D image by adding the overlapped images.

Abstract: The present invention discloses a stereoscopic image display system and a method of controlling the same. An eye tracking module locates current 3D spatial positions of the viewer's eyes, and generates the information of both left and right eyes' current 3D spatial positions. A control module controls a display device that can alter the direction of the light outputted, and outputs images on the display device in time multiplex mode. The light containing the left eye image is outputted to the position of left eye instead of right eye at one time point, and the light containing the right eye image is outputted to the position of right eye instead of left eye at another time point, so that a stereoscopic image is perceived according to the parallax theory. The present invention enlarges the visual range of stereoscopic image and achieves a better stereoscopic image visual experience for viewers.

Abstract: A method for self-recalibration of a structured light vision system including a camera and a projector. A camera plane and a projector plane are defined, a Homography matrix between the camera plane and the projector plane is computed, and a translation vector and a rotation matrix are determined from Homography-based constraints. A computer vision system implementing the method is also described.

Abstract: A vision system that forms a map of a scene proximate a platform, e.g., a vehicle, that determines the actual ground plane form the map, and that corrects the map for differences between the actual ground plane and an assumed ground plane. The vision system may remove the actual ground plane from the map to prevent false positives. The vision system can further identify and classify objects and, if appropriate, take evasive action.

Abstract: A source image (S) that is distorted by camera optics is transformed into a corrected image (T) by using a tabular imaging rule. This transformation occurs directly during the reading out from the image sensor and in real-time. No, one or several target pixels in the target image (T) are assigned to each source pixel of the source image.

Abstract: When a choice is made between several items offered in a first window on a display screen, a second window is displayed in front of the first window. An image of an watcher who is watching the display screen is captured to detect watcher's eye position relative to the display screen. When the watcher's eye position moves, the second window is displaced to uncover the first window in such a way that the second window moves upward in response to a downward movement of the eye position, downward in response to an upward movement of the eye position, rightward in response to a leftward movement of the eye position or leftward in response to a rightward movement of the eye position.

Abstract: A regression mirror reflects light from a light projector in a reflecting direction opposite an incident direction. A light receiver combined with the light projector in a unitary unit receives the reflected light from the regression mirror. A detecting unit including an optical sensing unit having the light projector, the light receiver and the reflecting member is disposed so that a wafer is disposed in a moving path along which an optical path of the optical sensing unit moves relative to the wafer. An information-acquiring unit acquires position information of the detecting unit relative to the wafer, an arithmetic unit calculates mapping information about an arrangement of the wafer based on the position information and light-reception information provided by the light receiver.

Abstract: The invention features an improved, photo hull based method of generating a three-dimensional representation of a visual scene based upon a set of multi-view reference images. In one aspect, a visual hull containing the visual scene is computed. Visibility of points on the computed visual hull with respect to each reference image is computed. Photo-consistency of points on the computed visual hull along rays back-projected from a desired view is computed based upon reference images having visibility of the points. A photo hull containing the visual scene is generated by stepping along each back-projected ray. The photo-consistent points visible in the desired view are colored using color information contained in reference images having visibility of the photo-consistent points.

Abstract: In a system in which images having parallax data, and which are made up of plural images containing the parallax information, are processed with viewing point conversion, and the resulting new images having parallax data are used, as in a system of generating a holographic stereogram, a unit for generating the images having parallax data is to be independent from other unit or units. To this end, the information necessary to perform viewing point conversion processing of converting the viewing point for an object is attached to images having parallax data when the images having parallax data have been produced. When the images having parallax data is exchanged between the unit for generating the images having parallax data and other unit or units, the exchanged images having parallax data need to be those to which the information has been attached.

Abstract: A method and apparatus for processing a geometric relationship between the image motion of pairs of points over multiple image frames representing a three-dimensional scene. This relationship is based on the parallax motion of points with respect to an arbitrary planar surface, and does not involve epipolar geometry. A constraint is derived over two frames for any pair of points, relating their projective structure (with respect to the plane) based only on their image coordinates and their parallax displacements. Similarly, a 3D-rigidity constraint between pairs of points over multiple frames is derived. Also disclosed are applications of these parallax-based constraints to solving three important problems in 3D scene analysis: (i) the recovery of 3D scene structure, (ii) the detection of moving objects in the presence of camera induced motion, and (iii) the synthesis of new camera views based on a given set of views. Moreover, this approach can handle difficult situations for 3D scene analysis, e.g.
