Ceiling lamps are sofas in scene 00000 #16
Comments
This may be a big issue. We directly adopt the semantic information from the raw database and map it to the NYUv2 label set. I will check this issue. |
Hi @Xia0ben Thanks for your comments. I have checked the provided case and found the semantic error. Since the semantic annotations are labeled by the human labors, the semantic annotation may contain such errors. Best, |
Hi again @bertjiazheng , Do you mean that the semantic.png images were 'hand-painted' by humans, were they not automatically generated from the 3D data ground truth ? Or do you mean the label associated with the ceiling lamp's 3D models was wrong ? Do you plan on having a further look into potential mislabelings and updating the dataset ? Wish you a pleasant day ;-). |
The 2D rendering is automatically generated by the rendering process. However, the semantic label for each 3D model is labeled by the human. |
So I guess there should probably not be much more labeling mistakes, then ? These flying sofas were probably just an exception (I must admit, a quite funny one) ? |
I think these cases are rare in our dataset. |
Hello again !
I succeeded in associating the 3D bounding boxes with semantic labels, and started digging around the dataset, and while exploring the first scene, I realized that the ceiling lamps were misidentified as sofas (you can check by simply using a color picker to compare the color of the sofas in the background with the ceiling lamps in image Structured3D/scene_00000/2D_rendering/485142/panorama/full/semantic.png). I'll try to put in place some automatic detectors and report back if I find any other incongruity.
Wish you a pleasant day.
