IMU Sensor Model Detection in D455

Hi,

I have started to write an Orientation filter from the data received from the IMU of D455. I stumbled upon one specific mention in the datasheet for D455. It says that the D455 camera may have BMI055 or BMI085 IMU sensor. It may be production timelines that newer cameras may have BMI085 inside.

Now both IMU sensors are exactly identical, except 16-bit accelerometer and Gyro measurement range sensitivity change in BMI085 for fusion purposes.

I am trying to implement sensor fusion from this repo.

https://github.com/xioTechnologies/Fusion

I need to decide on correct sensitivity values and therefore it is mandatory to know the correct IMU inside. It is required if my first assumption is true that D455 might have any of an IMU sensor (BMI055 / BMI 085). 

How to find that?

    Hi Rohit  Page 61 of the current edition of the data sheet document for the 400 Series cameras lists the product codes of the D455 models that contain the two types of IMU component.

    The KB number of the particular model that you own will be on a sticker on the base of the camera in small text.

    MartyG,

    Thank you.
    KISS: 'Keep It Simple Stupid' strategy would have worked well.
    I assumed that the codes are possible to extract from SDK to know the exact IMU sensor used. It is just Manufacturing Configuration code at the downside of the Camera. Mine is K83122-100; hence it is BMI055.
    Thanks for a quick reply. Now time to see how the fusion implementation proceeds.
