Hi All,
I am using visionworks library for calculating the disparity map using SGM algorithm. I wanted to know if there is any way to obtain the confidence score(or the cost ) of the disparity value predicted for every pixel int the image, using which I can improve the final disparity obtained by interpolation or some fusion technique.
Hi,
Instead of high-level API, you can get more information in our low-level API.
For example, in llsgm, aggregated_cost may be what you want.
Thanks.
Hi,
Thanks for your quick reply. Can you share link for the documentation of this function/API. I couldn’t find any.
Hi,
Semi-Global Matching document can be found at:
VisionWorks API
NVIDIA Extension API
Vision Primitives API
Semi-Global Matching
The source code of our low-level SGBM can be found here:
/usr/share/visionworks/sources/demos/stereo_matching/stereo_matching.cpp
Thanks.
Could you please tell me more specifically about where these relative document is? website, link? or kind of package? or where i can download these files
I has installed visionworks by installing Jetpack3.2, but i can not find the SGM documents you provided in my Jetson TX2
