How did you measure the Realsense D435 accuracy?

[MOgaw7]

I'm trying to measure the real precision using Intel Realsense D435 and our target objects. I found the document (https://www.intel.com/content/www/us/en/support/articles/000026260/emerging-technologies/intel-realsense-technology.html) which describe the accuracy is < 1%, but how did you measure that? In other words, how did you get the ground truth?
