摘要： In a machine vision system utilizing computer processing of image data, an imaging module incorporates the image sensor as well as pre-processing circuitry, for example, for performing a background subtraction and/or a gradient calculation. The pre-processing circuitry may also compress the image information. The host computer receives the pre-processed image data and performs all other calculations necessary to complete the machine vision application, for example, to determine one or more wheel alignment parameters of a subject vehicle. In a disclosed example useful for wheel alignment, the module also includes illumination elements, and the module circuitry provides associated camera control. The background subtraction, gradient calculation and associated compression require simpler, less expensive circuitry than for typical image pre-processing boards. Yet, the pre-processing at the imaging module substantially reduces the processing burden on the host computer when compared to machine vision implementations using direct streaming of image data to the host computer.
摘要翻译：在利用图像数据的计算机处理的机器视觉系统中，成像模块包括图像传感器以及预处理电路，例如用于执行背景减法和/或梯度计算。预处理电路还可以压缩图像信息。主计算机接收预处理的图像数据并执行完成机器视觉应用所需的所有其它计算，例如确定本车辆的一个或多个车轮定位参数。在用于车轮定位的公开示例中，该模块还包括照明元件，并且模块电路提供相关联的摄像机控制。背景减法，梯度计算和相关压缩需要比典型的图像预处理板更简单，更便宜的电路。然而，与使用图像数据的直接流传输到主计算机的机器视觉实现相比，成像模块的预处理大大降低了主机计算机上的处理负担。

摘要： An apparatus and method for calibrating machine vision measuring systems that have more than one camera are disclosed. A first calibration target is mounted in a fixed relationship to a first camera of the machine vision measuring system. A third camera mounted in a fixed relationship to a second camera of the machine vision measuring system. Second and third calibration targets are mounted in a fixed relationship to one another and viewable by the first camera and by the third camera. A data processor is programmed to compute calibration of the first camera and the second camera, based on a position of the second calibration target relative to the third calibration target and based on a position of the first camera with respect to the third camera. The apparatus and method provide a way to continuously measure the positions of two or more cameras used in the measuring system, and to use such measurements to calibrate the system. If the cameras move with respect to each other, their respective positions are calculated and used in subsequent measurements. The apparatus and method enable a machine vision measuring system to be used without field calibration at the time of installation.

摘要： A target system for determining the location of a position on a vehicle comprises a target body, one or more target elements, a trigger, and a point definer. The target elements are disposed on the target body and are detectable by a position determination system. The trigger is positioned on the target body and is remote from the position determination system. The trigger operates the position determination system by selectively changing the detection of one or more of the target elements by the position determination system. The point definer extends from the target body, and the point definer includes a point its a distal end. The point is capable of being located adjacent the position on the vehicle and is at a known location from the target body. The position determination system determines a location of the target body after detecting the target elements disposed on the target body. Methods of using the target system are disclosed.

摘要： The present disclosure provides a method and system for determining symmetry and Ackermann geometry status of the steering system of a vehicle. A system according to the disclosure determines symmetry of the steering system based on toe angle differences of the steerable wheels. Thus, no specification is required for determining symmetry of the steering system. A system according to the disclosure determines symmetry of the steering system based on normalized toe angles. Consequently, the steerable wheel does not have to be positioned at a specific angle. Additionally, the present disclosure determines symmetry in the steering system of a vehicle without requiring turning steering wheels through a large angular range. Hence, technician efforts in steering the wheel are reduced. The disclosure also provides an improved alignment procedure that implements determination of symmetry of the steering system into the alignment procedure. The present disclosure provides a novel machine-implemented procedure to determine Ackermann geometry status of a steering system based on theoretical Ackermann angles.

摘要： An improved position determination system that is resistant to interference caused by glint, such as from the Sun. The position determination system for determining positional parameters of an object has a target device comprising a base configured for attaching to the object, first and second target surfaces connected to the base; wherein the planes on which the first target surface and the second target surface are located are non-parallel to each other. The position determination system further comprises an image sensing device configured for forming a viewing path intersecting the target device and generating image information indicative of the geometric characteristics of the target device, and a data processing device configured to couple to the image sensing device for determining the orientation of the object based on the image information. If one of the target surfaces becomes obscured as a result of glint, the image of the other target surface alone is sufficient to determine object orientation.
