Abstract

The invention relates to a multi-target six-freedom-degree electromagnetic positioning device and method, and belongs to an electromagnetic positioning device and method, The device consists of a signal transmitting unit, a signal receiving unit, and a control and data processing unit. According to the positioning demands, the number of signal receiving sensors is selected, and the selected signal receiving sensors are fixed on a positioning target, and generate receiving signals through electromagnetic induction. The control and data processing unit receives a sampling signal, and executes an electromagnetic positioning algorithm. The device solves a problem that a conventional device is poorer in the tracking and positioning of a target moving in a large area in a space, optimizes the positioning method, simplifies a circuit, improves the positioning efficiency, and solves a problem of an error caused by the mutual impact of the position parameter and posture parameter solving processes during six-freedom-degree solving.

Description

technical field [0001] The invention relates to an electromagnetic positioning device and a positioning method, in particular to an electromagnetic positioning device supporting simultaneous operation of multiple signal receiving sensors and an electromagnetic positioning method for solving target positions and attitudes in parallel. Background technique [0002] With the continuous development of science and technology, positioning technology is widely used in auxiliary medical treatment, human-computer interaction, motion detection and analysis and other fields. During the movement of the human body, the limbs will make movements such as rotation and bending, and the positioning target may be blocked by other parts of the body. These problems make the research have high requirements for positioning technology. Compared with ultrasonic, photoelectric and other positioning devices, the device designed based on the six-degree-of-freedom electromagnetic positioning technology ...
