Abstract

A method for navigation of a movable platform is provided. The method includes the steps. First, a plurality of reflection devices is placed to mark a range. A coordinate location and a direction of the movable platform are received by a positioning system, At least one laser to measure relative positions and distances between the reflection devices and the movable platform are emitted by a laser range finder, respectively. Absolute locations of the reflection devices and the range are calculated by a processor according to the coordinate location and the direction of the movable platform, the relative positions and the distances between the reflection devices and the movable platform. The reflection devices are scanned and tracked by the processor, and the coordinate location and the direction of the movable platform and the absolute locations are calibrated by the processor to control the movable platform to move in the range.

Description

technical field [0001] The present invention relates to a navigation method and system, and in particular to a navigation method and system for a mobile platform. Background technique [0002] With the development of science and technology, service robots have gradually replaced many traditional human labor tasks, and various indoor and outdoor robots are gradually becoming popular in European and American markets. At present, the high-precision navigation of outdoor mobile platforms is mainly used in outdoor service robots. According to the market report statistics of WinterGreen Research, Inc (Robot Home Cleaning, Cooking, Pool Cleaning, and Lawn Mowing Market Strategy, Market Shares, and Market Forecasts, 2008-2014), outdoor service robots are still immature but Markets with high development potential, among which the market size of lawn mowing robots will reach USD 30.5 billion in 2014. [0003] The outdoor mobile platform, as the name suggests, is mainly used for larg...
