Abstract
A method for calibrating a sensor and projector with respect to a work area, the method including positioning a projector to project light indicators at locations in the work area and positioning a sensor with respect to the projector such that the sensor's field of view includes a selected portion of the work area. The sensor captures video or encoded data of activities at the work area. The sensor and projector are aimed at a set of coordinates upon the work area and the associated aim-point coordinates of the sensor and projector are recorded. The sensor and projector are aimed at additional sets of coordinates upon the work area, and the associated aim-point coordinates are recorded until a sufficient quantity of aim-point coordinates have been collected to form a calibration data set sufficient to calibrate the sensor and projector to the work area.
