HD camera

Asked by Freuk

Hi,
I have got a probleme with Artoolkit plus 2.2.1
it works fine still I use camera resolution with a 4/3 aspect ratio
but when a I use a HD ratio 1,7 1920X1080
the X coord of the marker are out of space when the marker move out of the middle of the screen to the right

I didn't see any constant or function dealing with aspect ratio in the code

can you point me to right place to make some modification so it can deal with HD resolution ?

thanks a lot for your help

I found the problem

this is due to store of distortion LUT in 16 bit short integer
in the file paramDistortion.cpp

Hi!
I am running in the same problem and unfortunately my knowledge is not good enough to understand what I should modify in the file paramDistortion.cpp

A bit more information on how his problem was solved would be great!

Oups joins didn't work .
can you use this link instead

https://cloud.recherche.enac.fr/public.php?service=files&t=31c3ce1d0dfda7c1a1874b61c4ee9596

after a short review of the code : the trouble was in the LUT represantion of 16 bit short
I replace the short interger by a LUT_Type
typedef struct _LUT_Type
  { ARFloat x, y; }
 LUT_Type;
 in Tracker.h
and in paramDistortion.cpp

hi, thank you for this post, this solved my problem.
UNFORTUNATELY, THIS IS NOT INCLUDED IN 2.3.0
do you plan to include this in future release?
thanks
