Excuse me, I have an Intel realsense d415 depth camera in my hand. I tried to calibrate it,so I downloaded the operation manual 《Intel ® realsense D400 series calibration tools - User Guide》 from the official website. I noticed that the manual said: 'Dynamic Calibration is optimizing extrinsic parameters and Intrinsic parameters such as distortion, field of view, principal point are not dynamically calibrated'.
Does this mean that Intrinsic parameters cannot be calibrated?If it can't be calibrated, will this affect the accuracy of the camera? Thanks a lot.

There is a special OEM version of the Dynamic Calibrator software aimed at manufacturers and engineering departments that has the ability to calibrate both intrinsics and extrinsics. It is available as part of Intel's OEM calibration system, which costs $1500 USD due to the cost of producing the large physical calibration chessboard.

Alternatively, if you do not need the board and you are an Intel Non Disclosure Agreement (NDA) customer then you may be able to request the software on its own from your Intel representative.
Overall though, calibration of intrinsics is not something that 99.9% of RealSense users have to be concerned about. It is calibration of extrinsics that has the most effect on image quality.

Yes, intrinsics and extrinsics are set in the factory. Although instrinsics can be calibrated if you have the software to do so, there is usually no need to do it.
You can view the extrinsics and extrinsics of the camera in detail using a tool called sensor-control, as described in the link below. The discussion describes its use with the SR305 camera model but it should work the same with the 400 Series cameras.
