METHOD FOR USE WITH AN OPTICAL ALIGNER SYSTEM FOR POSITIONING A FIXTURE RELATIVE TO A VEHICLE

摘要

A method is provided for positioning a free-standing fixture relative to a vehicle, using a visual aligner system for imaging vehicle-mounted targets with reference image sensors and processing the resultant images. Embodiments include calculating locations of the vehicle- mounted targets, calculating a location of a reference point on the vehicle, and determining a longitudinal line along a longitudinal axis of the vehicle. A location of a center of the fixture and an axis of the fixture is then calculated based on an image of one of the targets obtained by a remote image sensor attached to the fixture. The fixture is positioned by performing at least one of the steps of comparing the intersection of the longitudinal line and the axis of the fixture with the center of the fixture, comparing the location of the center of the fixture and the location of the reference point, comparing the location of the center of the fixture and a reference plane calculated by the visual aligner, and comparing the location of the axis of the fixture and the reference plane, and adjusting the fixture relative to the vehicle to achieve a desired position or orientation of the fixture based on the performed comparison steps and angle calculations.
