How to get all data using pyrealsense2.pyrealsense

[PierreLouisT]

Hello, I work with D455 realsense camera, I would like your advices. I read all of this document which tells what are the differents data SDK as accuracy, projector temperature, etc.. However, Some of data do not work using pyrealsense,
for example, in my code below, I can have the gain, projector temperature but not saturation using get_options

Hope you'll know what is my problem..
By the way do you know if I can get a more precise documentation, there are not description of each parameters and some of them are unknown for me (for example, Asic temperature or mc temperature, don't know what that is). I used realsense viewer to check some of parameters but no descritption found yet.
Thank you for your help,

PL

Hi @PierreLouisT If you are seeking to query the RGB saturation option then that would be inaccessible with depth_sensor, which queries the depth sensor. You would have to define a separate color_sensor option that queries the RGB sensor.

If you are querying sensors by their index number with a query_sensors instruction then '0' is the depth sensor and '1' is the RGB sensor.

If you are querying the sensor with a 'first sensor' instruction like get_device().first_depth_sensor() then you can create a get_device().first_color_sensor() for the RGB sensor, as demonstrated in a Python script at #10002 (comment)

The Advanced Mode functions are not documented, as they interact with each other in complex ways and so Intel chose to control them with machine-learning algorithms instead of creating documentation. If you would like information on one particular Advanced Mode function then I will be happy to discuss it with my Intel RealSense colleagues.

Intel's camera tuning white-paper guide at the link below is an excellent reference for learning how to adjust some of the RealSense settings.

ASIC temperature refers to the temperature of the camera's internal circuit board during operation, whilst projector temperature refers to the temperature of the camera's infrared projector component if that particular camera model is equipped with one.

Other temperature types such as MC, LLD and APD do not have official documented descriptions, though they are ones that are usually never needed to be used in a program, with ASIC and Projector being the most important ones.

An example of code for querying temperature with get_option in Python is provided at the link below.

Hi Marty !
Thank you for your clear response, effectively I made error, I used depth sensor instead of color sensor, so I understand better !
Ok I understand better why there is no documentation for advanced mode functions.
If I have any others questions, I come back here,
See you soon

You are very welcome, @PierreLouisT - please do feel free to ask further questions if you have them!
