Polygons automatically appearing in overlapping views
« on: February 11, 2021, 04:34:23 AM »
Hi all,

I use metashape to construct a 3D model from drone footage. Within the footage, I programmatically mark up polygons representing areas of interest. These automatically appear in overlapping views. Is there a way to suppress this. Ideally I want 1 shape to represent a feature regardless of the view that it appears in.

Regards,

Raj.

Hello Raj,

Do you mean to merge several overlapping polygonal shapes to the single shape?

Hi Alex,

Yes, effectively to merge two or more shapes into a single shape. Sorry for not being clear.

To give an example:

We detect (independently) objects within the scene and know the location on individual photos. Since the photos have overlapping views of the scene, the same object is detected multiple times. The object detection part of the code is oblivious to this. Hence at the time of mapping the polygons to the model,  we end up with overlapping (but slightly different) shapes depicting the same physical entity in the scene.

If there is some built-in functionality (or a particular way of dealing with it) in metashape to handle this, that is what I am after.

Regards,

Raj.
