Optical Velocity Tracking for Paint Spray Gun: 9,245,163


A method of tracking and reporting the velocity of a hand-held paint spray gun. The object to be painted is placed in a room having one or more fiducial walls. A camera is installed on the spray gun, with its field of view toward the one or more fiducial walls. As the object is painted, the camera detects fiducials, calculates their current position, and compares current positions to previous locations to determine movement and velocity. The current velocity is compared to a stored target velocity, and audible or visible feedback is provided to the spray gun operator.
