A lens and aperture device for determining 3D information. An SLR camera has a lens and aperture that allows the SLR camera to determine defocused information.
摘要:
Hardware and software methodology are described for three-dimensional imaging in connection with a single sensor. A plurality of images is captured at different degrees of focus without focus change of an objective lens between such images. Depth information is extracted by comparing image blur between the images captured on the single sensor.

摘要:
The subject system hardware and methodology combine disparate cameras into a cohesive gesture recognition environment. To render an intended computer, gaming, display, etc. control function, two or more cameras with non-coaxial axes are trained on a space to detect and lock onto an object image regardless of its depth coordinate. Each camera captures one 2D view of the gesture and the plurality of 2D gestures are combined to infer the 3D input.
摘要:
A system and method for determining instantaneously the three-dimensional coordinates of large sets of points in space is disclosed. This system uses two or more CCD cameras (or any other type of camera), each with its own lens and pinhole. The CCD's are all arranged so that the pixel arrays are within the same plane. The CCD's are also arranged in a predefined pattern. The combination of the multiple images acquired from the CCD's onto one single image forms a pattern, which is dictated by the predefined arrangement of the CCD's. The size and centroid on the combined image are a direct measure of the depth location Z and in-plane position (X,Y), respectively. The use of a predefined pattern enables high speed computation through simple algorithmic procedures. Moreover, the use of CCD cameras allows for the recording of such datasets at the corresponding image frame rate, thus opening the use of the invention to the mapping of dynamical systems.
