About the linear accelaration about avdata

Hi @Saixiaoma , can you tell us which log and time interval does this data snapshot belong to so that we can look on our end? Usually, you can expect spikes in imu data since it is subject to a lot of noise including the vibrations of the vehicle. You can remove this noise by using a low pass filter/moving-average filter or a KF

Hi guys, mine by contrast is so small. I wonder whether the gravity has been removed according to @Saixiaoma , but i'm not sure about this. All i want to know is whether i obtain a correct result.
Besides, most INS algorithms such as GPS/INS integration remove gravity inside the program, so i don't know how to deal with such a preprocessed dataset.
Would u please do me a favor?Thanks in advance!
