About bounding box #110

Open f499497201 opened 6 years ago

f499497201 commented 6 years ago

I am using sem_seg of Pointnet, about count the number of chairs, this part is very important for my paper.

But after running all codes. I don't know how to show result by bounding box , there is some .obj file but how to open them and show by box?

And do you have done about count the number of classes or not?

@f499497201 Hey friend, I come across the same problem. I need to perform instance segmentation by using point cloud. PointNet treats each point separately so that it doesn't have the correlation information with the neighbors. Therefore in my mind it's hard to generate the bounding box by using the basic PointNet model. I don't really sure if my understand is all right. Anyway, do you have solved this problem or do you have any idea about it?
