Abstract:
1. A method for navigation of a movable platform, used in a system; the system includes a plurality of reflection devices and a movable platform, wherein the movable platform further includes a positioning system, a laser range finder and a processor, the method comprising: placing the plurality of reflection devices to mark a range; receiving, by the positioning system, a coordinate location and a direction of the movable platform; emitting, by the laser range finder, at least one laser to measure relative positions and distances respectively between the plurality of reflection devices and the movable platform; calculating, by the processor, absolute locations of the plurality of reflection devices and the range according to the coordinate location and the direction of the movable platform, and the relative positions and the distances between the plurality of reflection devices and the movable platform; and scanning and tracking, by the laser range finder, the plurality of reflection devices, and calibrating, by the processor, the coordinate location and the direction of the movable platform and the absolute locations of the plurality of reflection devices to control the movable platform to move in the range; wherein when the processor calibrates the coordinate location and the direction of the movable platform and the absolute locations of the plurality of reflection devices, the method further comprising:
