Abstract

The invention provides a method and a system for automatically rectifying an attitude measuring device. The method is implemented by the aid of a transmitting module, a receiving module and a processing module. The transmitting module comprises the attitude measuring device and a transmitting device, laser planes can be transmitted by the transmitting device, and the receiving module comprises at least two light sensing devices. Compared with the prior art, the method has the advantages that the laser planes can be transmitted by the transmitting device, different characteristic light signals can be received by the receiving module, angular zero points of x-axes, y-axes and z-axes can be repositioned, accordingly, influence due to error accumulation of the attitude measuring device can be reduced, inadaptation feel can be decreased for users, immersion can be improved, and the method has important significance on 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 ...
