The embodiment of the invention provides an individual soldier posture measurement method and apparatus. The method comprises the following steps: if the current acceleration is within a preset acceleration interval, obtaining an adaptive parameter according to an acceleration error value, a magnetic field strength error value and an adaptive function, wherein the acceleration error value is obtained based on the current acceleration, and the magnetic field strength error value is obtained based on the current magnetic field strength; calibrating the current angular rate based on the adaptiveparameter to obtain a calibrated angular rate; and obtaining a posture angle of an individual soldier device based on the calibrated angular rate. According to the method and apparatus provided by theembodiment of the invention, the current angular rate is calibrated based on the adaptive parameter that is obtained via the acceleration error value, the magnetic field strength error value and theadaptive function, the posture angle is obtained based on the calibrated angular rate, the posture measurement of the individual soldier device is achieved, the influence of environmental factors on the individual soldier posture measurement error is reduced, and the adaptive capacity to environment of the individual soldier device is improved. In addition, according to the method, no additional hardware device needs to be added, and the practicability is high.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular to a method and device for measuring attitude of an individual soldier. Background technique [0002] With the development of mobile communications, security agencies such as anti-terrorism, firefighting, public security, special services, and border security can use individual equipment to locate criminal suspects and achieve information detection and security protection. Due to the complex working environment of individual equipment, it is particularly important to confirm the direction of the individual and plan the path in time to shorten the time for arresting suspects. The focus is to reduce the impact of environmental interference on attitude measurement sensors, namely accelerometers, gyroscopes, and magnetic sensors, and improve attitude measurement accuracy. [0003] Due to the low accuracy of the sensors used by individual equ...
