  • Patent number: 8294809
    Abstract: The present invention determines the dimensions and volume of an object by using a novel 3-D camera that measures the distance to every reflective point in its field of view with a single pulse of light. The distance is computed by the time of flight of the pulse to each camera pixel. The accuracy of the measurement is augmented by capture of the laser pulse shape in each camera pixel. The camera can be used on an assembly line to develop quality control data for manufactured objects or on a moving or stationary system that weighs as well as dimensions the objects. The device can also ascertain the minimum size of a box required to enclose an object.

  • Patent number: 8237849
    Abstract: An image-pickup apparatus is disclosed which is capable of realizing a focus-effect function in a constant time without being influenced by contrast of an object or the position of a focus lens. The apparatus includes a signal generator which generates a focus evaluation signal, a detector which detects information corresponding to an object distance, and a controller which performs focus lens control on the basis of the focus evaluation signal and focus lens control on the basis of information corresponding to the object distance. The controller determines a direction and a velocity in which the focus lens is moved toward an in-focus position on the basis of the information corresponding to the object distance in the focus lens control according to the focus-effect function. The controller performs the focus lens control on the basis of the focus evaluation signal after the focus lens is moved in the determined direction.

  • Patent number: 8233075
    Abstract: Methods and systems for adjusting a video imaging system that includes an auto-focus mechanism wherein an input from a user of the video imaging system invokes an auto-focus procedure. Responsive to the input, the auto-focus mechanism is scanned over a range of focal distance from a first setting to a second setting indicated by the input. A sequence of images using the video imaging system is captured while scanning the auto-focus mechanism over the range. The images in the sequence are processed so as to compute a measure of focal quality with respect to each of the images. The measure of the focal quality is analyzed so as to select an optimal focal distance, and the auto-focus mechanism is set to the selected focal distance.

  • Patent number: 8139142
    Abstract: RGB-Z imaging systems acquire RGB data typically with a high X-Y resolution RGB pixel array, and acquire Z-depth data with an array of physically larger Z pixels having additive signal properties. In each acquired frame, RGB pixels are mapped to a corresponding Z pixel. Z image resolution is enhanced by identifying Z discontinuities and identifying corresponding RGB pixels where the Z discontinuities occur. Thus segmented data enables RGB background substitution, which preferably blends foreground pixel color and substitute background color. The segmented data also enables up-sampling in which a higher XY resolution Z image with accurate Z values is obtained. Up-sampling uses an equation set enabling assignment of accurate Z values to RGB pixels. Fixed acquisition frame rates are enabled by carefully culling bad Z data. Segmenting and up-sampling enhanced video effects and enable low cost, low Z resolution arrays to function comparably to higher quality, higher resolution Z arrays.

  • Patent number: 8139141
    Abstract: An RGB-Z sensor is implementable on a single IC chip. A beam splitter such as a hot mirror receives and separates incoming first and second spectral band optical energy from a target object into preferably RGB image components and preferably NIR Z components. The RGB image and Z components are detected by respective RGB and NIR pixel detector array regions, which output respective image data and Z data. The pixel size and array resolutions of these regions need not be equal, and both array regions may be formed on a common IC chip. A display using the image data can be augmented with Z data to help recognize a target object. The resultant structure combines optical efficiency of beam splitting with the simplicity of a single IC chip implementation. A method of using the single chip red, green, blue, distance (RGB-Z) sensor is also disclosed.

  • Patent number: 8134637
    Abstract: An imaging system substantially simultaneously acquires z-depth and brightness data from first sensors, and acquires higher resolution RGB data from second sensors, and fuses data from the first and second sensors to model an RGBZ image whose resolution can be as high as resolution of the second sensors. Time correlation of captured data from first and second sensors is associated with captured image data, which permits arbitrary mapping between the two data sources, ranging from 1:many to many:1. Preferably pixels from each set of sensors that image the same target point are mapped. Many z-depth sensor settings may be used to create a static environmental model. Non-correlative and correlative filtering is carried out, and up-sampling to increase z-resolution occurs, from which a three-dimensional model is constructed using registration and calibration data.
