Abstract

The invention provides a method for automatically correcting an attitude measuring device. The method comprises a transmitting module, a receiving module and a processing module, wherein the transmitting module comprises the attitude measuring device and a transmitting device; the transmitting device can transmit a laser surface; the receiving module comprises a CCD camera. Compared with the prior art, the method has the advantages as follows: in the way that the transmitting device is used for transmitting the laser surface, while the receiving module is used for receiving optical signals with different characteristics, positions of x-axis, y-axis and z-axis angular zero points are adjusted, so that influence caused by error accumulation of the attitude measuring device is reduced, an inadaptation sense of a user is reduced, an immersion sense is increased, and thus the method has a relatively large significance for somatosensory operation and virtual reality.

Description

technical field [0001] The invention relates to the field of attitude measurement, and more specifically, to a method and system for automatic correction of an attitude measurement device. Background technique [0002] Attitude measurement generally uses attitude measurement devices to measure angle information. There are many types of attitude measurement devices. Using three-axis geomagnetic decoupling and three-axis accelerometers, they are greatly affected by the acceleration of external forces. In environments such as motion / vibration, the output direction angle error Larger. In addition, the geomagnetic sensor has disadvantages. Its absolute reference is the magnetic field lines of the geomagnetic field. Geomagnetism is characterized by a wide range of use, but its strength is low, about a few tenths of a gauss, and it is very susceptible to interference from other magnets. The angular velocity output by the gyroscope is an instantaneous quantity. The angular velocity ...
