摘要： A machine vision vehicle wheel alignment system configured with at least one cameras for acquiring images of the wheels of a vehicle, and an associated light projectors configured to project a pattern image onto the surfaces of vehicle components such as vehicle wheel assemblies. Images of the projected patterns acquired by the camera, are processed by the vehicle wheel alignment system to facilitate a determination of the relative orientation and position of the surfaces such as wheel assemblies in three dimensional space, from which vehicle parameters such as wheel alignment measurements can be subsequently determined.

摘要： An optical target for temporary application in non-determined placement on a surface of an object such as a vehicle wheel assembly within the field of view of an imaging sensor of a machine vision vehicle service system. The optical target consists of a flexible body which is relatively thin and generally flat, capable of conforming to the contours of a surface onto which it is secured in releasable manner by a means of adhesion. A set of visible optical elements are disposed on a front face of the target body for observation and imaging by the imaging sensors.

摘要： A system for measuring vehicle alignment angles has a plurality of sensor elements for mounting to wheels of a vehicle to be aligned. The system uses the sensor elements to measure various angles such as steer ahead angle and toe, and the system also has a display for displaying information to a user and a memory for storing operating instructions for the system. Operating instructions are stored in the memory for determining from compensation measurements taken at a minimum of first and second longitudinally displaced positions whether the toe parameter of two wheels falls outside a predetermined toe range, and whether the steer ahead angle of the vehicle falls within a predetermined range. The operating instructions stored in the memory further include instructions responsive to the toe parameter falling outside the toe range to control the system to display to the user information indicative of the need to adjust the toe parameter before taking additional compensation measurements. The operating instructions stored in the memory further include instructions responsive to the toe parameter not falling outside the toe range and to the steer ahead angle falling outside the predetermined range to control the system to display to the user information indicative of the need to adjust steer ahead angle before taking additional compensation measurements.

摘要： A method and apparatus for comparing reference planes during a vehicle wheel alignment procedure using a machine vision vehicle wheel alignment system. The machine vision vehicle wheel alignment system is configured to acquire position and orientation data associated with at least one optical target disposed in a field of view, to establish a first reference plane associated with a surface on which a vehicle undergoing an alignment procedure is disposed. Positional information associated with each wheel of the vehicle is then acquired by the machine vision vehicle wheel alignment system, and utilized to establish a second reference plane associated with each wheel of the vehicle. Differences between an orientation of the first reference plane and an orientation of the second reference plane are determined and identified to an operator or utilized to characterize components of the vehicle or vehicle support surface.
