Three-dimensional positioning method and three-dimensional positioning system

Abstract

The invention discloses a three-dimensional positioning method and a three-dimensional positioning system, the three-dimensional positioning method comprises the following steps: acquiring a three-dimensional accelerated speed of a positioning object relative to a first coordinates and an included angle between a coordinate axis of the first coordinates and the direction of the gravity accelerated speed, the first coordinates is a dynamic coordinates with the centre of the positioning object as an original point, the original point of the first coordinates and the direction of the coordinate axis thereof are changed following the movement of the positioning object; acquiring the original speed of the positioning object; determining the displacement of the positioning object on z axis and a horizontal coordinates which is reversely parallel to the direction of the gravity accelerated speed according to the three-dimensional accelerated speed of the positioning object relative to the first coordinates, the included angle between the coordinate axis of the first coordinates and the direction of the gravity accelerated speed, and the original speed of the positioning object. The three-dimensional positioning method and the three-dimensional positioning system of the invention have low dependency on the environment and high reliability.

Description

Technical field [0001] The invention relates to a three-dimensional positioning method and a three-dimensional positioning system. Background technique [0002] At present, the development of three-dimensional positioning technology is very rapid, and there are many methods for measuring three-dimensional motion parameters, including electromagnetic methods and optical methods. [0003] The electromagnetic method mainly relies on the generation of a space magnetic field, and analyzes the movement characteristics by collecting the electrical parameter changes that occur when the positioning object moves in the space magnetic field. The disadvantage is that the magnetic field is easily disturbed, so the requirements for the environment are high. [0004] The optical method mainly uses optical image processing technology to collect and analyze the motion characteristic parameters. The optical three-dimensional positioning method can capture the real-time motion of the positioning ob...
