Abstract
An improved method of calibrating a laser projector to reference points includes the steps of moving a reflective member in the path of a laser beam. The reflective member is moved towards a reference point, and a control for the laser projector operates in one mode of operation to move the laser beam with the reflective member. The reflective member is moved, and moves the laser beam towards one of the reference points. Once the laser beam is adjacent to the reference point, the reflective member is removed from the laser beam member. The laser projector then identifies the location of the reference point, and begins to calibrate itself relative to the work surface. This process is repeated until the calibration is complete.
Claims19
A method of calibrating the position of a laser projector relative to reference points comprising the steps of:
- (1) providing a plurality of reference points;
- (2) providing a laser projector opposite said reference points;
- (3) directing a laser beam from said laser projector;
- (4) moving a reflective member into the path of said laser beam such that a portion of said laser beam is reflected by said reflective member back to said laser projector;
- (5) moving said reflective member towards one of said reference points;
- and
- (6) moving said laser beam with said reflective member until said laser beam is directed adjacent said one of said reference points to begin to calibrate the position of said laser projector relative to said one reference point.
A method of calibrating the position of a laser projector relative to reference points comprising the steps of:
- (1) providing a plurality of reference points adjacent to a work surface;
- (2) providing a laser projector opposite said work surface;
- (3) directing a laser beam from said laser projector in a pattern;
- (4) moving a reflective member into the path of said laser beam, such that a portion of said laser beam is reflected by said reflective member back to said laser projector;
- (5) moving said reflective member toward one of said reference points, the reflective beam of said laser beam being reflected back to said laser projector;
- (6) identifying the movement direction of said reflective member from the reflected portion of said laser beam;
- (7) moving said laser beam in said direction;
- (8) removing said reflective member from said laser beam;
- (9) said laser beam beginning to search for the exact location of said reference point, and beginning to calibrate the position of said laser projector relative to said reference point.
