I want to make my own dataset #23

Lizhinwafu commented 1 year ago

I have apple tree point cloud dataset with two semantic classes trunk, branch. One line of my annotation data is as follows. 0.013332, 0.111240, 1.698000,112.000000,109.000000,102.000000, 0.000000, 0.000000

There are 8 columns in total：x,y,z,R,G,B, semantic label(trunk is 0/branch is 1), instance label(trunk is 0, branch1 is 1,branch2 is 2,...). I'm not sure if this is right and need your help. I use CloudCompare for annotation.

Many thanks.

That is how I usually annotate my data. Just make sure you understand which semantic label will be ignored when training and testing the model. For instance, in STPLS3D ground is labeled as 0, and will not be evaluated.

I annotated the tree into two semantic categories, trunk and branch, but I'm not sure what the instance category is. I think it's also tree trunks, branches？

I used -100 as the instance label for all the ground points that have the semantic label of 0 in STPLS3D. I believe you could use -100 as the instance label for the trunk points in your data.

Many thanks. Hello, have you already made your own label and trained it successfully?

But what if I want to evaluate both classes? @meidachen @Greatest-Marx @Lizhinwafu

你的意思是你既想评估实例标签为-100的对象，又想评估标签为1的对象？
