How can I visualize wireframes in a perspective image?

[godhj93]

Hi there,

I'm currently trying to visualize wireframes in a perspective view and I have some difficulties understanding a few things.

From what I understand, there are two types of annotation files - 'annotation_3d.json' for each scene and 'layout.json' for each perspective view of each scene. However, I'm struggling to comprehend the relationship between the 'lineJunctionMatrix' in 'annotation_3d.json' and the 'junctions' in 'layout.json' for wireframe visualization.

Is there available code that can illustrate how these concepts are connected?

Any advice or direction you could give me on this would be greatly appreciated.

I also want to know what junctions's ID is "None" in "layout.json" means

Thank you so much for your time and assistance!

Hi,

You can find more details in data_organization.md about these annotations.

Here are some clarifications.

• The annotation_3d.json is the annotation of the house design, while the layout.json is the annotation of the corresponding perspective image.
• In layout.json, the junctions with none ID correspond to fake junctions (such as junctions created by the intersections between the room wireframe and image boundary).

Best, Jia
