  Hi Almog,

  I think there is an example for extracting the IMU data you can refer to.

  Here is page for examples for the depth camera provided by RealSense SDK.

  Regards,

  Rizal

  Hi
  
  The example only helps me to get the ROTATION...
  I need to know the camera's movements (right, left, forwards ...)

  Hi Almog,
  
  Sorry about that.

   

  You can get accelerator's data directly but there is no position data as this would have to be derived from the raw data.

   

  The IMU in the L515 provides gyro and acceleration data but not pose data. The only camera that provides pose data is the T265. If you want pose data from the L515, you will have to calculate it on the host (maybe by double integrating the acceleration but there is the gravitational component of the acceleration that you may need to subtract or filter out).

  
  Regards.

  Hi Rizal
  
  Thank you for your answer.
  
  How accurate will be the calculation of the pose from the raw data ? 
  There is a small inaccuracy of the accelerator component, double integrating it will make the inaccuracy bigger 
  And all available data from the component it a function of time, so the longer the time the bigger the inaccuracy 
  
  Am I missing something ? 
  
  Thanks,
  Almog

  Hi Almog,

   

  I could not estimate the accuracy.

  Yes you are correct, the inaccuracy would be problematic

  .

  There is an example of a similar implementation of your goal but it requires addition of a T265 camera.

  There is no readily available feature on the L515 to tell the position of the camera between 2 frames.
