I have tried to call knn_points
function from chamfer.py
and I can set K more than 1,and calculating chamferdist sucessfully.
But I still wants to know the difference that the calculate direction when doing the chamferdist function between ver. 0.3.0 and ver 1.0.0 and also the meaning of dist we got.
Hi, thanks for sharing the code.
I was using chamferdist as my model loss, and it works very well.
And now I saw the 1.0.0 version of chamferdist has KNN points,
how can I switch the chamferdist into KNN points? Just set K into a number that what I want?
Or I have to call the
KNN_points
function inchamfer.py
file? Because I did't see this inExample.py
file.Oh, one more question.
when I use chamferdist in version 0.3.0,
I just call chamfer function like:
dist1, dist2, idx1, idx2 = chamfer(source_pts, target_pts)
and then(torch.mean(dist1)) + (torch.mean(dist2))
to get the chamfer loss which I can get the chamfer distance from source_pts to target_pts and the chamfer distance from target_pts to source_pts at the same time, right? (Because I'm not pretty sure about this.)And now in 1.0.0 version, I have to change the code into
dist1, idx1 = chamfer(source_pts, target_pts)
anddist2, idx2 = chamfer(target_pts, source_pts)
because chamferdist only calculate in one way in version 1.0.0, right?Thanks!
