Excuse my wording. I will use the picture below to explain what I mean. I want to use the surface normals for each arrow shown like below to draw lines parallel to each plane like the image shown below the first one. Therefore I want to obtain point coordinates given in black dots.

Assuming I have a unit normal (u, v, w) to each plane, how can this be accomplished?

  • $\begingroup$ Normals dont tell how far that plane is. But im sure same ai has a depth estimate too. $\endgroup$

  • $\begingroup$ yes i have depth maps. so how can i do that if i have the depth information? $\endgroup$ Nov 16, 2020 at 5:59
  • $\begingroup$ Depth + knowledge of camera FOV is 3D data $\endgroup$

  • $\begingroup$ so in effect the surface normal has no use in this application? $\endgroup$ Nov 16, 2020 at 14:45
  • $\begingroup$ Well, it can make triangulation easier. Its also useful for a system to validate the data. $\endgroup$
