Claim Text:
1. A method of obtaining coordinates of an item within a room, the method comprising: placing a laser measuring device at a first reference position within the room, wherein the laser measuring device is capable of being aimed in different directions to measure distances from the first reference position to respective surfaces at which the laser measuring device is aimed; aiming the laser measuring device at a first corner of the room and measuring a first reference-to-corner distance between the first reference position and the first corner with the laser measuring device; aiming the laser measuring device at a second corner of the room and measuring a second reference-to-corner distance between the first reference position and the second corner with the laser measuring device; determining coordinates of the first reference position by minimizing a first function of the first reference-to-corner distance and the second reference-to-corner distance; aiming the laser measuring device at the item and measuring a first reference-to-item distance between the first reference position and the item with the laser measuring device;
