Hi,

I just acquired livox tele15 lidar and I'm still struggling to get the built-in IMU data.

I'm using the livox viewer, the IMU rate is set to 200 Hz, and when I export my recorded file to a .csv file, I only get type 2 point cloud data.

Am I doing something wrong ?

Thanks for you help

I figured out that it was the conversion from .lvx to .csv that just wipped out my IMU datas. I've been able to found them in the bin .lvx file.

Hi,
I just tried the livox viewer2 and i am able to collect the data but i converted the .lvx2 file into csv and the IMU data is not present.
Could you please give the the steps from the begining to record the point cloud and the IMU data and read them for further processing.

Thanks.

Hi,

When converting the .lvx2 file to a .csv, it only converts LIDAR data, not the one from IMU. If you open the binary .lvx2 file (with Python, for example) you can find the IMU data though, meaning it's the conversion process that removes those IMU data.

What I've done is use a Python script to record data and save it, without using livox viewer.
