DistortionRGB = 0 ( d415)

[omerbrandis]

Dear support,

I have used "CustomRW -r " to get an xml of a d415 camera,
the file generated includes the following section

1 1920 1080 1381.06 1380.51 960.317 500.743 **0 0 0 0 0**

the values for DistortionRGB seem wrong ...
can someone please explain them ?

( running ubuntu 16.04, Firm ware : 05.09.11.00,
librealsense2.so.2.9.1 ( otherwise CustomRW will not run) )

thanks,
Omer.

Please see #1430

[omerbrandis]

I have reviewed #1430, and accept the answer written there.

can you please also shed some light on

960.317 500.743

a. the value 500.743 is a bit surprising since its very far from half of the total number of pixel on axis y (1080)

b. should the values for PrincipalPoint change for different resolutions?
and if so, can i use CustomRW to generate them ? ( i did not see a that CustomRW has a resolution parameter).

Thanks,
Omer.

i see that github has altered my last post.

the values i received for PrincipalPointRGB are : 960.317,500.743.

hi @omerbrandis,

for your question a) it seems a bit far from 540, but calibration handled this.
b), i don't think the value change for different resolutions.
