Wrong Depth value by D435i
Hi,
I used the D435i depth camera videos for an instance segmentation. I want to find out the distance between the sponge and the surface. This is done by referencing between the surface and the sponge. Unfortunately the camera shows me every time initially the wrong values until it is moved. Does anyone here know if this is a hardware or software problem?
To find out the value, I placed the camera above the table and moved the sponge over the 10 fields. For the first field I get a wrong output value every time, the rest of the outputs are ok.
This is the Output of the csv file:
The sponge wasn´t moved before reaching frame 100.

Hi Tiago May
Do you have auto-exposure enabled, please? If you do then it is good practice to skip the first several frames after the pipeline is started to give the auto-exposure time to settle down. It is not necessary to do this frame skip when auto-exposure is disabled and manual exposure values are used.
An example of script code for skipping the first several frames can be found at the link below.
