加速度计校准
加速度计必须在首次使用或飞行控制器方向发生改变时进行校准。 否则通常无需重新校准（除非在冬季使用时， 飞行控制器出厂时未进行温度校准thermally calibrated）。
INFO
加速度计校准不良通常会被飞行前检查和拒绝解锁提示所捕获（GQC 的警告信息通常显示为“加速度计零偏过高” 和 “一致性检查失败”）。
TIP
这与罗盘校准 类似，区别在于每个姿态下需要将机体保持静止（而非旋转）。
执行校准
QGroundControl will guide you to place and hold your vehicle in a number of orientations (you will be prompted when to move between positions).
The calibration steps are:
Start QGroundControl and connect the vehicle.
Select "Q" icon > Vehicle Setup > Sensors (sidebar) to open Sensor Setup.
Click the Accelerometer sensor button.
INFO
You should already have set the Autopilot Orientation. If not, you can also set it here.
:::
Click OK to start the calibration.
Position the vehicle as guided by the images on the screen. Once prompted (the orientation-image turns yellow) hold the vehicle still. 该位置标定完成后，屏幕上的相应图示将变成绿色。
INFO
The calibration uses a least squares 'fit' algorithm that doesn't require you to have "perfect" 90 degree orientations. Provided each axis is pointed mostly up and down at some time in the calibration sequence, and the vehicle is held stationary, the precise orientation doesn't matter.
:::
- 在机体的所有方向上重复校准步骤。
Once you've calibrated the vehicle in all the positions QGroundControl will display Calibration complete (all orientation images will be displayed in green and the progress bar will fill completely). You can then proceed to the next sensor.
