依照內文是 time accelerometer gyroscope magnetometer
若是即時的輸入這些數據,就可以即時的看到姿態嗎?
需要將校正數據寫入mpu9250的register中嗎?
謝謝您的回覆

数据的采集: 我的方法是把传感器粘在篮球上,把篮球放到透明胶带的圆环上,通过转动篮球,使传感器呈现不同姿态,采集数据。
姿态融合上: 在哪一步做校正(乘以校正参数),我个人觉得都不是问题。看你的代码习惯了。

请问您采集的caldata是mpu9250的原始数据吗,mpu9250加速度计和磁力计的坐标系不一致,有没有做坐标系统一的处理呀,我想用caldata的数据做校正和滤波,所以想了解一下,谢谢

采集的是原始数据,坐标系不一致csdn博客上说明了。代码上设置好直接用

cal_data 都没有小数 全是整数数据
加速度计数据这么大??

数据是原始数据

这是我的原始数据

原始数据使用您的方法进行校正,感觉出来的数据完全不对。不知道是哪里出错了

可能不是数据问题,可能是你用算法的问题吧,我的博客你再好好读读吧。

我看了你的博客, 我还是没搞懂 这个CALDATA 文件 是怎么得来, 是用arduino 加MPU9250 吗?

imu数据通过蓝牙传手机上来的。
