Abstract

The invention discloses a method for automatically correcting an attitude measurement device. A transmitting module, a receiving module and a processing module are involved, wherein the receiving module comprises the attitude measurement device, a gravity detection device and a receiving device; the transmitting module comprises a transmitting device, and the transmitting device can transmit a laser plane; the receiving module comprises at least two light induction devices. Compared with the prior art, according to the method disclosed by the invention, by utilizing a way of transmitting the laser plane by the transmitting device and receiving different characteristic light signals by the receiving device, the zero position of an angle between the x axis and the z axis can be regulated, the influence brought by error accumulation of the attitude measurement device is reduced, a maladjustment sense of a user is reduced, an immersion sense is increased, and great significance in somatosensory operation and virtual reality is obtained.

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 ...
