    Abstract: An imaging element is configured by arranging a plurality of light receiving elements with respect to each micro lens. A second PD selecting/composing unit has a mode for generating right-eye image data and left-eye image data from the output signal of the imaging element. A phase difference detecting unit detects a phase difference from right-eye image data and left-eye image data. A movement detecting unit detects the movement of an object from right-eye image data or left-eye image data. A CPU calculates an object position based on both the result of phase difference detection and the result of movement detection and drives a focus lens via a driving unit to thereby control focus adjustment.

  • Publication number: 20130162785
    Abstract: A method and a system are provided integrating inter-pose constraints, which are weighted in a step of “bundle adjustment” in a localization application (SLAM). The inertial data associated with a motion model serve to predict the pose of the system at the instant of a new image. This prediction is then used to construct an inter-pose constraint. A technique arising from learning theory selects the weighting coefficient (ratio of the noise of the covariance signals) in an efficient manner. The inter-pose constraint thus weighted is then integrated within the cost function of the bundle adjustment.

Estimated cross-correlations may be generated via convolution of a measured autocorrelation function with a velocity probability density function, and the velocity coefficients iteratively optimised to minimise the error between the estimated cross-correlations and the measured cross-correlations.

    Abstract: A single-lens 2D/3D camera has a light valve placed in relationship to a lens module to control the light beam received by the lens module for forming an image on an image sensor. The light valve has a light valve area positioned in a path of the light beam. The light valve has two or more clearable sections such that only one section is made clear to allow part of the light beam to pass through. By separately making clear different sections on the light valve, a number of images as viewed through slightly different angles can be captured. The clearable sections include a right section and a left section so that the captured images can be used to produce 3D pictures or displays. The clearable sections also include a middle section so that the camera can be used as a 2D camera.

  • Patent number: 8350894
    Abstract: A method is disclosed for performing stereoscopic imaging. The method may involve obtaining a first image of a scene, at a first time, using a camera disposed on a platform, where the distance between the camera and the scene is changing. The camera may be used to obtain a second image of the scene, at a second time, with one of the first and second images being larger than the other. One of the images that is larger than the other may be resized so that the sizes of the two images are substantially similar. Both of the images may be rotated a predetermined degree so that the images form a stereo pair that may be viewed with a stereoscope viewing component or made into an anaglyph for viewing with an anaglyph viewing component.

  • Patent number: 8350895
    Abstract: An improved method of making stereoscopic pictures comprising photographing a scene with a camera spaced from the scene, moving the camera generally parallel to the scene while producing a plurality of pictures of the scene each taken at a different position relative to the scene, and separating the pictures into stereo pairs for viewing. Photographing and moving steps can be performed and the separating step can be done as soon as the pictures are available for viewing to produce the stereo pairs. Alternatively, the photographing and moving steps can be done at one time and the separating step can be done at subsequent times to produce the stereo pairs of the invention thereby allowing stereo pairs to be produced from existing motion pictures, computer generated images, videotapes and still photographs. The method can be used utilizing drones, satellites, rockets, slings and other vehicles to move the camera(s).

    Abstract: Apparatus and systems, as well as methods and articles, may operate to capture a portion of an omniscopic or omni-stereo image using one or more image capture media. The media may be located substantially perpendicular to a converging ray originating at a viewpoint on an inter-ocular circle and having a convergence angle between zero and ninety degrees from a parallel viewpoint baseline position that includes a non-converging ray originating at the viewpoint. The media may also be located so as to be substantially perpendicular to a non-converging ray originating at a first viewpoint at a first endpoint of a diameter defining an inter-ocular circle, wherein the origin of the non-converging ray gravitates toward the center of the inter-ocular circle as spherical imagery is acquired.

    Abstract: A 3D model of an object is rendered using centered images of the object. An algorithm executed locally or in a distributed manner calculates camera positions for the images and determines a virtual camera path based on the camera positions. The application adjusts the images to fit the plane of the virtual camera path and fills in the gaps between the images using transition renderings. To improve user experience, the application also calculates resting positions for navigation stop points using a spring system. Upon constructing the 3D model, the application can transmit the 3D model to a variety of user devices including the network connected device having a camera module that captured the images.

  • Patent number: 8330803
    Abstract: In a method for 3D digitization of an object (1), a plurality of camera images of the object are recorded and assembled to determine the 3D coordinates of the object. To improve such method, pictures are taken from the object (1), from which 2D feature points (11, 12, 13; 21, 22, 23) of the object (1) are determined. The 3D coordinates of the 2D feature points are determined. The 2D point correspondences (32, 32, 22) between the 2D feature points of a picture and the 2D feature points of another picture are determined. Several of these 2D point correspondences are selected, and an associated 3D transformation is determined. The quality of this 3D transformation is determined with reference to the transformed 3D coordinates of the 2D feature points. Valid 3D feature points are determined therefrom. For assembling the camera images of the object (1), the 3D coordinates of the valid 3D feature points are used.

    Abstract: A three-dimensional pose of the head of a subject is determined based on depth data captured in multiple images. The multiple images of the head are captured, e.g., by an RGBD camera. A rotation matrix and translation vector of the pose of the head relative to a reference pose is determined using the depth data. For example, arbitrary feature points on the head may be extracted in each of the multiple images and provided along with corresponding depth data to an Extended Kalman filter with states including a rotation matrix and a translation vector associated with the reference pose for the head and a current orientation and a current position. The three-dimensional pose of the head with respect to the reference pose is then determined based on the rotation matrix and the translation vector.

    Abstract: A capturing method for a plurality of images with different view-angles and a capturing system using the same are provided. The capturing method for the images with different view-angles includes the following steps. An appearance image of an object is captured by an image capturing unit at a capturing angle. A light reflection area of the appearance image is detected by a detecting unit, and a dimension characteristic of the light reflection area is analyzed by the same. Whether the dimension characteristic of the light reflection area is larger than a first predetermined value is determined. If the dimension characteristic of the light reflection area is larger than the first predetermined value, then the capturing angle is adjusted within a first adjusting range. After the step of adjusting the capturing angle within a first adjusting range is performed, the step of capturing the appearance image is performed again.
