Semi-Global Block Matching parameters

Hello,

 

I am using IMAQ Stereo Correspondence (SG Block Matching) VI function and I am trying to adjust the parameters (Postfilter Options, Filter Cap and Correspondence Options). I was able to find some suggestions on the values, but I was wondering about the units of the parameters. In specific, do I have to change the parameters when I change the resoluton of my input images or it does not depend on it?

For example, for a parameter called Uniqueness Ratio in Postfilter Options it is said: "Generally, a uniqueness ratio of 5 to 10 is sufficient to remove spurious disparities." Should I understand it as it does not matter what is my input resolution?

 

Greetings,

Patrycja

Hi, 

 

Not really sure, but I think there is no need to change anything because of resolution. 

Do you mean that the Right Image In & Left Image In , for example, have different resolutions?

 

Thx.
