    摘要： A method for determining distances for chassis measurement of a vehicle having a body and at least one wheel includes determining a center of rotation of a wheel of the vehicle by projecting a structured light pattern at least onto the wheel, recording a light pattern reflected by the wheel using a calibrated imaging sensor system, determining a 3D point cloud from the reflected light pattern, and determining the center of rotation of the wheel from the 3D point cloud. The method also includes determining a point on the body by evaluating the previously determined 3D point cloud or by evaluating a plurality of grey-scale images recorded under unstructured illumination. A height level is determined as a vertical distance between the center of rotation of the wheel and the point on the body.

    摘要： An apparatus for measuring the dynamic characteristics of the vehicle wheel alignment in non-contact fashion with high accuracy is disclosed. A laser light source (4) emits a laser beam of a predetermined geometric pattern toward the wheel side surface. A laser beam control device (6) controls the width of the laser beam in such a manner as to be radiated only in a predetermined range of the wheel side surface. Two laser light sources (120), (121) emit non-parallel laser beams. A photdetecting device (122) receives the two laser beams and converts them to two corresponding image data. A processing unit calculates the distance between the two images based on the two image data and calculates the wheel alignment based on the same distance.

    摘要： A non-contact type wheel alignment measuring apparatus includes a fixed-focal-length lens and a pair of light sources located on the opposite sides of the lens for projecting a pair of laser beams onto the side surface of a wheel to be measured. The apparatus also includes a CCD sensor on which images reflecting from the wheel are formed and the distance between the two images is detected as a function of pixels of CCD sensor between them. The information of this distance (or the number of pixels) is utilized to determine the distance between the measuring apparatus and a point of interest on the wheel. With two or more such information for different locations on the wheel, its alignment characteristic, such as toe-in and camber angles, can be determined.

    摘要： A sensor method and apparatus for an optical wheel alignment machine utilizes one or more light sources, such as lasers, to project a laser line or other shaped light onto various locations about the sidewall of a tire undergoing measurement. The sensor includes a video camera or other light responsive receiver and a optical system that combines the reflected laser lines into a single image that is received by the camera. The optical system also rotates one or more of the reflected laser lines so that all of the reflected portions have the same general orientation upon entering the camera. The camera outputs a video data stream that is indicative of the image. The sensor has an electronic circuit that analyzes this video data stream in real time to determine the location in the image of a preselected feature of each of the laser lines. The circuit then outputs coordinate data indicative of the location of this feature.

The sensor includes a video camera or other light responsive receiver and a optical system that combines the reflected laser lines into a single image that is received by the camera. The optical system also rotates one or more of the reflected laser lines so that all of the reflected portions have the same general orientation upon entering the camera. The camera outputs a video data stream that is indicative of the image. The sensor has an electronic circuit that analyzes this video data stream in real time to determine the location in the image of a preselected feature of each of the laser lines. The circuit then outputs coordinate data indicative of the location of this feature.The circuit is microprocessor-based and uses a comparator that compares the incoming video data stream with a threshold to determine, on a pixel-by-pixel basis, whether any particular pixel lies on or outside one of the laser lines received by the camera. For a pixel lying on a laser line, the comparator interrupts operation of the microprocessor which then determines the position within the image of that pixel. Once the pixel representing the preselected feature is found, the microprocessor uses that information to generate the coordinate output data.
