    摘要： A method for testing cameras includes positioning a camera such that an image of a target is displayed on a monitor within at least one default image parameter. The method further includes engaging a dimming condition of a light source from the camera, thereby generating a lighting condition signal. Subsequently the camera receives the lighting condition signal and displays it on the monitor. A group of observers then analyze the lighting condition signal. The method continues through engaging a second dimming condition of the light source from the first camera, thereby generating a second lighting condition signal, which is also displayed on the monitor. The group of observers then analyzes the second lighting condition signal.

    摘要： A vision enhancement system 10 which aids the driver in visually identifying a sensed object 16 without diverting his/her attention from the road ahead. One or more sensors 20 used to collect information about the vehicle's environment are operatively coupled with a controlled source of illumination 38. A processor 24 receives input from the sensors and intelligently determines whether a particular object sensed in or near the current path of the vehicle requires alerting the driver. If so, the processor outputs a control signal 30 to effect illumination of the sensed object. The source of illumination is controlled so as to continuously direct light onto the identified object, even as the vehicle and/or object move simultaneously with respect to one another.

    摘要： A blind spot monitoring system for a vehicle includes two pairs of stereo cameras, two displays and a controller. The stereo cameras monitor vehicle blind spots and generate a corresponding pair of digital signals. The display shows a rearward vehicle view and may replace, or work in tandem with, a side view mirror. The controller is located in the vehicle and receives two pairs of digital signals. The controller includes control logic operative to analyze a stereopsis effect between each pair of stereo cameras and the optical flow over time to control the displays. The displays will show an expanded rearward view when a hazard is detected in the vehicle blind spot and show a normal rearward view when no hazard is detected in the vehicle blind spot.

    摘要： Methods and apparatus for representing a three-dimensional object by means of a High Density Point Data Model (HDPDM) consisting of a large number of individual data values, each of which specifies the coordinates of a point on the surface of a three dimensional object. An initial HDPDM is produced by scanning a physical object, tessellating the elements of a CAD representation of the object surface, or evaluating mathematical expressions which describe the surface. Further data values define a virtual tool surface which is spaced from the modeled object surface. The projection of the virtual tool surface on the object surface along projection lies parallel to a defined axis of projection identifies selected points on the surface which are modified by effectively moving them to the tool surface. The tool surface may be translated with respect to the object surface along a predetermined trajectory, with the tool surface being iteratively used to operate on an area of projection on the model surface to provide a virtual machining process which performs free-form alterations on the data model. The finished data model may then be used to create a physical part or generate an output CAD or mathematical model which defines a free-form part.

    摘要： A method for capturing data representative of a geometry of a raw cylinder head casting in order to obtain a casting scanning coordinate system for use with a machining coordinate system utilizes a locating device during a non-contact scanning operation. The cylinder head casting includes horizontal planar cast locators and vertical cast locators. Planar data corresponding to the planar cast locators is determined by scanning planar areas of the device. Vertical data corresponding to the vertical cast locators is determined utilizing locating features disposed on a planar surface of the device and located at predetermined positions with respect to the vertical cast locators. A transformation matrix defining a relationship between the scanning coordinate system and the machining coordinate system can then be determined based on the planar and vertical data so that virtual machining can be performed in predicting the volume of a machined cylinder head.
