Filed:

Feb 25, 2010

Appl. No.:

12/712786

Inventors:

Shawn Marsee - Cape Canaveral FL, US

International Classification:

G01B 7/30

US Classification:

33288, 73 175

Abstract:

A system for aligning a vehicle to an object and a method for calibrating same is disclosed. The system comprises three light sources which are calibrated when the vehicle and object are in desired alignment. After initial calibration, the light sources project images which converge in a predetermined configuration on a reflecting surface. The reflecting surface is positioned in a fixed location relative to the object to which the vehicle is being aligned. The convergence of the projected images indicates to the operator of the vehicle that the vehicle and the object are in desired alignment. The light sources may be rotatably attached to the vehicle such that the roll, pitch, and yaw of each light source may be adjusted during calibration.

Abstract:

An activation system and method for an optical alignment system that may comprise one or more sensors selected from the group consisting of accelerometers, gyroscopes, magnetometers, Inertial Measurement Units (IMUs), and pressure sensors. The system may also comprise at least one limit switch. The sensors and switch provide signals containing information about the movement, position or orientation of the system to a controller. The controller uses the sensor and switch information to estimate the position or orientation, or both, of the system. The system activates the optical alignment light source when predetermined thresholds are exceeded. Filtering such as low-pass, high-pass, and other filtering such as Kalman filtering may be used to remove unwanted frequencies from the filter data prior to processing by the controller. The invention may comprise the activation system alone or in combination with an optical alignment system. An exemplary use is for forklift optical alignment systems.
