SYSTEM AND METHOD FOR CONTINUOUSLY PROJECTING A REFERENCE AID AT AN ACTIVITY SITE

摘要

An apparatus and method for projecting reference aids at sites characterized by continuous activity over periods which long enough to encompass both full daylight and artificial light only ambient lighting conditions. Variations in ambient light intensity are detected over the course of the activity period, and at least one laser projection system is operated responsive to the detecting to project a line which is visible continuously throughout the site activity period. The projected line serves as a reference aid for guiding operation of vehicles and equipment as they approach or depart a particular processing station of the site.

主权项

1. A computer implemented method comprising:
receiving, at a computer controlled laser projection system, a request to project at least one line extending from a first site location, over a site activity period, as a reference aid for use in at least one of approaching and departing the first site location; detecting variations in ambient light intensity during the site activity period; operating at least one laser source of the laser projection system, responsive to the detecting, to project a lane which is visible continuously throughout the site activity period.
