To answer your questions:
1. If the D435 is brand new it should not have the need to be calibrated unless you are having a faulty lecture on any of the streams. Are you having any issue with the quality of the streams?
2. If you are looking to calibrate the D435 you will need to follow this document: https://www.intel.com/content/dam/support/us/en/documents/emerging-technologies/intel-realsense-technology/RealSense_D400_Dyn_Calib_Programmer.pdf
Regarding the error you are receiving, can you please tell me what calibration tool are you using and what was the procedure you were following to perform the calibration?
Same problems here...we have 5x D415s and 2x D435s and can calibrate all cameras we've received except for a shipment of 2x D415s which have the same error as the original post about tables.
Things we've tried:
1) Flashing all the different firmwares on the Intel site - no change
2) Hardware reset in realsense-viewer - no change
3) Trying to run tools in Windows instead of Ubuntu 16.04 - no change
In our case, we do need to calibrate them again, they've been bumped around in shipment and the calibration is off by a cm or two, so a fix would be great!
Thanks for your reports about this issue. In order for the RealSense engineering team to further investigate on the issue can you please provide me the exact reproduction steps that you are following to receive this error?
Additionally in the following link you will find the Dynamic Calibration User's guide:
I will be waiting for your feedback.
No problem, to replicate the issue, the cameras were taken directly out of the box, and we used the "Intel ® RealSenseTM Depth Module D400 Series Software Calibration Tool" PDF to install then calibrate. This was:
1) Got the tool (section 3.1.1 of above document in Ubuntu 16.04):
a) Get dependencies (
sudo apt-get update sudo apt-get install libusb-dev libusb-1.0-0-dev sudo apt-get install libglfw3 libglfw3-dev sudo apt-get install freeglut3 freeglut3-dev sudo apt-get install libpng12-dev)
b) Set up apt:
echo 'deb http://realsense-hw-public.s3.amazonaws.com/Debian/apt-repo xenial main' | sudo tee /etc/apt/sources.list.d/realsense-public.list sudo apt-key adv --keyserver keys.gnupg.net --recv-key 7DCC6F0F sudo apt-get install librscalibrationtool
2) Run tool from terminal
3) Press start on calibration and the error it gives in the log window at the bottom is:
This is consistent across 3 separate Ubuntu 16.04 installs, and one Windows install (again following the PDF directions to install/calibrate).
Flashing instructions were followed from the PDF as well on flashing, and flashing reports a success when finished as well.
I'm about 90% sure this is a hardware fault (or the calibration tables in memory are shipped corrupt) as these processes work fine on the cameras that do work.
I have just received the following information from the RealSense engineering team.
There is a mismatch between the calibration tables in the Intel RealSense Dynamic Calibrator 188.8.131.52 and newer versions of the Intel RealSense D400 series cameras. A new version of the Dynamic Calibrator is required. This tool is in development right now but we do not have a schedule for release yet.
We are working to have this issue fixed as soon as possible. When the new Dynamic Calibrator tool is ready we will have it anounced on the front page of the community.
Thanks for your patience and understanding.
Adding to this answer, I don't think the updated tool will fix this. Some of the cameras we got that used to calibrate with no issues no longer will calibrate despite us making no changes to the firmware. The fact that working cameras have now failed is starting to seem like a PCB or corrupted memory issue. Any news from the engineering team on fixes?
If not we now have 3-4 DOA cameras....

Engineering has shared a workaround for you to try with the calibration tool:
Download the calibration tool from:
Run the command: Intel.Realsense.CustomRW.exe -g
This may help restore the calibration table.
Please let us know your results.
Thank you for contacting Intel Customer Support.
As you can also see in the print screen you sent, you will need to run a Dynamic Calibrator Software.
You can find the software for Windows 10, on the following link: https://downloadcenter.intel.com/download/27415/?v=t
Let me know if this works.
