Abstract

The invention provides a method for automatic correction of an attitude measurement device. The method adopts a transmitting module, a receiving module and a processing module, the receiving module comprises the attitude measuring device, a gravity detection device and a receiving device, the transmitting module comprises a transmitting device which is capable of transmitting laser planes, and the receiving device comprises a CCD (charge coupled device) camera. Compared with the prior art, the method has advantages that by the transmitting device for transmitting the laser planes and the receiving device for receiving optical signals with different characteristics, x-axis, y-axis and z-axis angle zero positions can be adjusted, influences resulted from error accumulation of the attitude measurement device are reduced, inadaptation of a user is relieved while immersion is improved, and the method is greatly significant to motion sensing operations and visual 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 ...
