Abstract

A machine vision vehicle service system including a console unit, optical sensors, and optional optical targets for disposition within fields of view of the optical sensors. The console unit contains a central processing unit configured with multiple processing cores and which is configured with image processing and vehicle service software applications adapted for execution on the multi-core processor. The console further incorporates various operator interfaces, including a keyboard, a mouse, a printer, and a display device. The optical sensors are coupled to the computer, and are aligned with fields of view which may encompass the wheels or components of a vehicle undergoing an alignment inspection.
