摘要： A method of instance segmentation in an image and a system for instance segmentation of images. The method includes identifying, with a processor, a starting pixel associated with an object in an image, the image having a plurality of rows of pixels, the starting pixel located in a row of the plurality of rows; identifying, with the processor, at least one pixel located in an adjacent row to the row in which the starting pixel is located, the at least one pixel being part of the same object as the starting pixel; iterating the previous two identification steps using the at least one identified adjacent row pixel as a start pixel for the next iteration; and connecting, with the processor, the at least one identified adjacent row pixels to form polylines representing the object.

摘要： A method for measuring wheel alignment of a test wheel rotating about a z-axis using at least one camera and a processor includes obtaining a calibration point from a calibration image of a zero-offset wheel that is the same size as the test wheel and that rotates about the z-axis, obtaining at least one test image of the test wheel with the camera and a non-structured light source, and locating a measurement point in the test image. The measurement point coincides with a radius that the calibration point is offset from the z-axis and the angular displacement of the calibration point from the vertical diameter of the zero-offset wheel. The measurement point is further located based on a change of reflectivity between other points in the test image adjacent the measurement point.

摘要： A hybrid wheel alignment system and methodology use passive targets for a first pair of wheels (e.g. front wheels) and active sensing heads for another pair of wheels (e.g. rear wheels). The active sensing heads combine image sensors for capturing images of the targets with at least one spatial relationship sensor for sensing a relationship between the active sensing heads. One or both of the active sensing heads may include inclinometers or the like, for sensing one or more tilt angles of the respective sensing head. Data from the active sensing heads may be sent to a host computer for processing to derive one or more vehicle measurements, for example, for measurement of parameters useful in wheel alignment applications.

摘要： A machine vision vehicle wheel alignment system optical target assembly which incorporates an adaptor for attachment of an optical target to a vehicle wheel assembly. The adaptor includes a circular sinusoidal edge for seating in a non-determined position against surfaces of a vehicle wheel assembly, and a pair of pivoting arm assemblies capable of independent movement which are configured to position tire hooks for gripping the tread surfaces of a tire mounted to the wheel rim. Forces exerted between the pivoting arms are transferred to the tire hooks to hold the optical target assembly in contact with the wheel assembly surface. The optical target is integrated into the adaptor, and maintained in a stationary relationship to the wheel assembly thereby during a vehicle wheel alignment procedure.
