Abstract
A machine vision system is configured to facilitate placement of a vehicle service apparatus relative to an associated vehicle. The machine vision system is configured to utilize images of optical targets received from one or more cameras to guide the placement of the vehicle service apparatus relative to the associated vehicle.
Claims11
An improved machine vision vehicle wheel alignment system having at least one camera, a computer operatively coupled to the at least one camera, the computer configured with vehicle wheel alignment software, and at least one optical target configured for attachment to a vehicle within a field of view of the at least one camera, wherein the improvement comprises:
- at least one additional camera mounted to a positionable vehicle service apparatus which is separate from the alignment system and is positionable relative to the vehicle, said at least one additional camera operatively coupled to the computer, said at least one additional camera disposed to include at least one optical target in an associated field of view;
- and
- wherein said computer is further configured to utilize images of the at least one optical target received from said at least one additional camera to guide the placement of said positionable vehicle service apparatus relative to the vehicle.
An improved machine vision vehicle wheel alignment system having at least one camera, a computer operatively coupled to the at least one camera, the computer configured with vehicle wheel alignment software, and at least one optical target configured for attachment to a vehicle within a field of view of the at least one camera, wherein the improvement comprises:
- at least one additional optical target configured for attachment to a positionable vehicle service apparatus within a field of view of the at least one camera, said positionable vehicle service apparatus separate from the alignment system and positionable relative to the vehicle;
- and
- wherein said computer is further configured to utilize images of the at least one additional optical target received from the at least one camera to guide the placement of said positionable vehicle service apparatus relative to the associated vehicle.
A method for aligning a positionable vehicle service apparatus relative to an associated vehicle utilizing a separate machine vision vehicle wheel alignment system having at least one camera, a computer operatively coupled to the at least one camera, the computer configured with vehicle wheel alignment software, and at least one optical target configured for attachment to a vehicle within a field of view of the at least one camera, comprising the steps of:
- mounting the at least one optical target on the associated vehicle in the field of view of the at least one camera;
- acquiring, at the computer, data representative of the position and orientation of one or more components of the associated vehicle from one or more images of the at least one optical target acquired by the at least one camera;
- mounting at least one additional camera on the positionable vehicle service apparatus, said at least one additional camera operatively coupled to the computer and having a field of view including the at least one optical target;
- acquiring, at the computer, data representative of the position and orientation of the positionable vehicle service apparatus relative to the associated vehicle from one or more images of the at least one optical target acquired by said at least one additional camera;
- and
- guiding placement of the positionable vehicle service apparatus relative to the associated vehicle utilizing said acquired position and orientation of the one or more components of the associated vehicle and said acquired position and orientation of the positionable vehicle service apparatus.
A method for aligning a positionable vehicle service apparatus relative to an associated vehicle utilizing a separate machine vision vehicle wheel alignment system having at least one camera, a computer operatively coupled to the at least one camera, the computer configured with vehicle wheel alignment software, and at least one optical target configured for attachment to a vehicle within a field of view of the at least one camera, comprising the steps of:
- mounting the at least one optical target on the associated vehicle in the field of view of the at least one camera;
- acquiring, at the computer, data representative of the position and orientation of one or more components of the vehicle from one or more images of the at least one optical target acquired by the at least one camera;
- mounting one or more additional optical targets on the positionable vehicle service apparatus, said one or more additional optical targets in a field of view of the at least one camera;
- acquiring, at the computer, data representative of the position and orientation of the positionable vehicle service apparatus relative to the associated vehicle from one or more images of the at least one additional optical targets acquired by the at least one camera;
- and
- guiding placement of the positionable vehicle service apparatus relative to the associated vehicle utilizing said acquired position and orientation of the one or more components of the associated vehicle and said acquired position and orientation of the positionable vehicle service apparatus.
