摘要
惯性测量单元是三轴陀螺和三轴加速度计提供包含运动物体姿态和位置信息的6个独立惯性参数,3个敏感轴严格互相垂直才能构成空间的直角坐标系,零偏和标度因数是影响精度的最大因素,并且对温度非常敏感,对精度产生非常大的影响,这个时候就必须进行标定,建立误差模型进行补偿。
Inertial measurement unit is triaxial gyro and three-axis accelerometer contains motion body posture and position information of six independent inertia parameters,three sensitive axis strictly perpendicular to each other to form the space rectangular coordinate system,zero bias and scale factor is the biggest factor affecting accuracy,and is very sensitive to temperature,a very large influence on precision,this time it is necessary to calibrate,error model is established to compensate.
