  • Patent number: 8749619
    Abstract: In illustrative implementations of this invention, multi-path analysis of transient illumination is used to reconstruct scene geometry, even of objects that are occluded from the camera. An ultrafast camera system is used. It comprises a photo-sensor (e.g., accurate in the picosecond range), a pulsed illumination source (e.g. a femtosecond laser) and a processor. The camera emits a very brief light pulse that strikes a surface and bounces. Depending on the path taken, part of the light may return to the camera after one, two, three or more bounces. The photo-sensor captures the returning light bounces in a three-dimensional time image I(x,y,t) for each pixel. The camera takes different angular samples from the same viewpoint, recording a five-dimensional STIR (Space Time Impulse Response). A processor analyzes onset information in the STIR to estimate pairwise distances between patches in the scene, and then employs isometric embedding to estimate patch coordinates.

    Abstract: A broadband imager, which is able to image both IR and visible light, is disclosed. In one embodiment, an IR sensitive region of an IR pixel underlies the R, G, B sensitive regions of R, G, and B visible pixels. Therefore, the IR pixel receives IR light through a same surface area of the photosensor through which the R, G, and B pixels receive visible light. However, the IR light generates electron-hole pairs deeper below the common surface area shared by the RGB and IR pixels, than visible light. The photosensor also has a charge accumulation region for accumulating charges generated in the IR sensitive region and an electrode above the charge accumulation region for providing a voltage to accumulate the charges generated in the IR pixel.

    Abstract: Digitizing objects in a picture is discussed herein. A user presents the object to a camera, which captures the image comprising color and depth data for the front and back of the object. For both front and back images, the closest point to the camera is determined by analyzing the depth data. From the closest points, edges of the object are found by noting large differences in depth data. The depth data is also used to construct point cloud constructions of the front and back of the object. Various techniques are applied to extrapolate edges, remove seams, extend color intelligently, filter noise, apply skeletal structure to the object, and optimize the digitization further. Eventually, a digital representation is presented to the user and potentially used in different applications (e.g., games, Web, etc.).

One or more SLEDs have a sufficient power, such as 75-200 milliwatts, to extend in a field of view in an area such as a room in a home. To correct for chromatic aberration which would otherwise exist due to the wider range of wavelengths which are emitted by an SLED compared to a laser, an achromatic diffractive optical element is used to disperse the light over the field of view. The achromatic diffractive optical element can have a stepped multi-level profile with three or more levels, or a continuous profile. Based on a tracked movement of a human target, an input is provided to an application in a motion tracking system, and the application performs a corresponding action such as updating a position of an on-screen avatar.

  • Publication number: 20110074923
    Abstract: Disclosed herein is a system which transmits an image using a lossless compression method in a robot to provide a service over a network and a method thereof. The network-based robot separates an image acquired by a stereo camera into various image formats and transmits the various image formats to a service server. The service server synthesizes the separated image formats to suit an image request such as face recognition, object recognition, navigation or monitoring to restore and provide an original image. When the network-based robot transmits the separated image formats to the server, the original image is transmitted using the lossless method to improve the performance of the server. Even when a service using a new image is added, separated images are transmitted with respect to the image format requested by this service to more flexibly cope with the service using the new image. Since channels are separated in order to receive lossless data, network gain is obtained.

  • Publication number: 20110069151
    Abstract: A dual lens camera for producing a three-dimensional image includes plural lens systems and a zoom mechanism. Initial correction data is constituted by a displacement vector of an amount and a direction of misalignment between plural images according to a superimposed state thereof for each of zoom positions of the lens systems. A vector detector, if a calibration mode is set, obtains a current displacement vector related to one first zoom position. A data processor outputs current correction data by adjusting the initial correction data according to the initial correction data and current displacement vector. If the current correction data is stored, a displacement vector is obtained from the current correction data according to a zoom position of the lens systems upon forming the plural images, to carry out image registration between the images according to the obtained displacement vector for producing the three-dimensional image.

    Abstract: To make it possible to stably provide a stereoscopic image which can be viewed by each viewer in the state where the stereoscopic effect and the sense of reality are maximized. Left eye and right eye images (images for measurement), the parallax between which is continuously or stepwise changed, are outputted beforehand to a stereoscopic image display device, and the face of the viewer viewing the images for measurement is photographed. The pupil width of the photographed viewer is measured, and based on the state of the change in the pupil width, the fusion limit of the viewer is measured and registered. In the case where a stereoscopic image for appreciation is displayed, the stereoscopic image is outputted by controlling the parallax of the stereoscopic image so as to prevent the parallax from exceeding the fusion limit of the viewer, which is measured beforehand.
