Method and device for realizing all-round installation of electronic compass

Abstract

The invention discloses a method and device for realizing all-round installation of an electronic compass. The method for realizing all-round installation of the electronic compass comprises the following steps: when calibrating, sensor data is collected in a default installation mode and user calibration parameters of the sensor are calculated; when measuring, calibration data is calculated through a pre-configured algorithm by using the sensor data and the user calibration parameters; coordinate system conversion is performed according to the installation mode selected by the user and the calibration data to obtain installation mode data; an installation mode posture of the electronic compass is calculated and output through the pre-configured algorithm using the installation data; whensetting zero, the zero setting posture of the electronic compass corresponding to the user installation error is obtained through a pre-configured zero setting and zero clearing rule using the installation mode posture; and the installation mode posture, the zero setting posture and a magnetic declination are used to remove the installation error of the user and the deviation of the magnetic declination through a pre-configured method to obtain the final posture of the compass. The beneficial effects of the invention are as follows: the all-round installation of the electronic compass is realized, the use space of the compass is fully utilized, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of electronic compass, in particular to a method and device for realizing omni-directional installation of electronic compass. Background technique [0002] Electronic compass, also known as digital compass, compared with traditional compass, electronic compass has the advantages of low energy consumption, small size, light weight, high precision, miniaturization and digitization. At present, it has been widely used in various industries such as military, aviation, aerospace, navigation, navigation, robotics, and intelligent machinery. [0003] Electronic compass is composed of magnetometer, accelerometer and MCU, and some even add gyroscope, which can realize the dynamic use of compass. The magnetometer is used to measure the magnetic field (terrestrial magnetic field and interference magnetic field), and the accelerometer is used to measure the acceleration of gravity. The MCU needs to process the signals...
