    摘要: A three-dimensional input apparatus for generating data specifying the shape of an object by receiving the light from the object is disclosed. The detection light is irradiated toward the object by a projector so as to scan a virtual surface. An image sensing device detects the light reflected from the object. A controller thins out data and outputs it to the image sensing device in a direction corresponding to the main scanning direction of the virtual surface of the image sensing device. The controller also controls the image sensing device such that the light-receiving signal is repeatedly read on a line along the direction of movement of the received detection light in an effective area constituting a part of the image sensing surface thereby to read the light-receiving signal in the effective area.

    摘要: An apparatus and method for detecting a three-dimensional image. The apparatus includes a projector which projects a reference light on an object; an image sensor which senses an image of the object; and a controller for controlling the projector and the image sensor, wherein the image sensor includes an aperture that restricts the passage of entering light; and an aperture controller for setting an aperture value for the aperture when receiving a two-dimensional image input, and setting an aperture value for the aperture when receiving a three-dimensional image input. The aperture value is set based on the intensity of received reference light. A processing unit determines the position of the object based on a relationship between an illumination direction of the reference light at the determined time center Npeak and an entrance direction of the reference light relative to the target pixel. A flicker detector detects a change frequency in light received by the image sensor, and the controller controls the image sensor to sense frames of an image at a frequency which is a multiple of the detected change frequency.

An image for calculating the three-dimensional shape of the target object and an image for displaying the target object are both captured by the same sensor. The displayed image is a grayscale image that is based on a centroid that is calculated from multiple data samples taken for each pixel in the image as the target is being scanned.

    摘要: A three-dimensional measurement device employs a slit ray projection technique to optically determine a three-dimensional image. The device offers a choice in operating modes between high-speed measurement, high-resolution measurement and large dynamic range in the depth direction, to accommodate various situations. The different modes of operation are achieved by selectively modifying one or more of the scanning speed of a projected reference beam, the readout speed of a photosensor, the line width or line spacing of the photosensor, and the number of lines per image frame.
