Described herein is a method of calibrating a three-dimensional imaging system. During calibration, a position and an orientation of the three-dimensional imaging system is determined with respect to a first parameter comprising a real world vertical direction (V_w) and to a second parameter comprising an origin of a three-dimensional scene captured by the imaging system. The first and second parameters are used to derive a calibration matrix (M_C2w) which is used to convert measurements from a virtual coordinate system (M_c) of the three-dimensional imaging system into a real coordinate system (M_w) related to the real world. The calibration matrix (M_C2w) is used to rectify measurements prior to signal processing. An inverse calibration matrix (M_w2c) is also determined. Continuous monitoring and adjustment of the setup of the three-dimensional imaging system is carried out and the calibration matrix (M_c2w) and its inverse (M_w2c) are adjusted accordingly.

A method and system for localizing a vehicle in a digital map includes generating GPS coordinates of the vehicle on the traveled road and retrieving from a database a digital map of a region traveled by the vehicle based on the location of the GPS coordinates. The digital map includes a geographic mapping of a traveled road and registered roadside objects. The registered roadside objects are positionally identified in the digital map by longitudinal and lateral coordinates. Roadside objects in the region traveled are sensed by the vehicle. The sensed roadside objects are identified on the digital map. A vehicle position on the traveled road is determined utilizing coordinates of the sensed roadside objects identified in the digital map. The position of the vehicle is localized in the road as a function of the GPS coordinates and the determined vehicle position utilizing the coordinates of the sensed roadside objects.

A broadside coupled connector assembly has two sets of conductors, each separate planes. By providing the same path lengths, there is no skew between the conductors of the differential pair and the impedance of those conductors is identical. The conductor sets are formed by embedding the first set of conductors in an insulated housing having a top surface with channels. The second set of conductors is placed within the channels so that no air gaps form between the two sets of conductors. A second insulated housing is filled over the second set of conductors and into the channels to form a completed wafer. The ends of the first and second sets of conductors and the blades are jogged in both an x- and y-coordinate to reduce crosstalk and improve electrical performance.

A method and apparatus for determining the distance of each pixel or a set of pixels in images acquired by cameras and thus imaging the three-dimensional profiles of objects in the images is described A source of illumination is projected through a mask of two-dimensional pattern onto the objects and images from predetermined and different view points are captured by a camera or cameras. A computer algorithm is used to identify a pixel or a set of pixels in each area of the pattern in each acquired image. The distance of the pixel or the set of pixels in the images is uniquely calculated by using the X, Y coordinates of the pixel or the set of pixels in the images of different view points and the positional relationship of the different view points. The three-dimensional profile of objects in the images is determined by collecting the distance information of each pixel or an area of pixels in the images.

A feature extractor samples points on an input pattern drawn in real time. In addition to X and Y coordinates, each sample has an up/down or Z coordinate value representing whether or not the sample point is a perceptible part of the pattern. The groups of coordinate values are transformed into respective sets of coefficients of Chebyshev polynomials by least-squares fit. A recognition unit can use the coefficients as features to identify the character. Additional features, such as aspect ratio and center of gravity, are also derived to aid in recognizing the pattern or reconstructing its image.
