Object recognition on large object (statue)

June 10, 2021 - 2:15am #1


I'm working on a project where I want to be able to recognize a statue (see the attached file) and then add some anatomic informations in augmented reality.

My first thought was to use the AreaTarget feature to scan the room with the statue but it's not optimal because if the room changes, it wont work anymore.

That brings up two questions.

- Is it possible to isolate the statue with green screens or white sheets for example so the scan would only contain the statue ? We could add some texture on the statue to help the recognition.

- Is there an other option ? I didn't find a lot of informations about the object recognition on large objets like statues, would it work?


Thanks for your time !


edit: We could also use model targets but I don't know much about cad models

I believe that in this case the usage of area target is not appropriate.

Possibly the best option is to use an model target if you could obtain  or create a model of this statue (best option). OK, if no model is available  possibly you can try to create a model via some 3d scan  3th party application ( I suspect   that 3d   object scanner  application for android will not work in this case) . So if you could create a more accurate model of the statue to any of the supported formats for the Model Target generator app (please, see note below about the supported formats) . Then you can try to create a model target and try to use it in this case

For more information, see Model Targets Supported Objects & CAD Model Best Practices.


Supported Format for MTG:

The MTG supports reading of: Creo View (.pvz), Collada (.dae), FBX (.fbx), IGES (.igs, .iges), Wavefront (.obj), STEP (.stp, .step), STL (.stl, .sla), VRML (.wrl, .vrml), glTF 2.0. When Creo View Adapter for JT is installed, then JT data is also supported.

NOTE: The MTG for macOS does not support STEP (.stp, .step) and JT data files.

The best import results have been observed with Creo View Adapter, Collada, FBX, and JT.

NOTE: Supported texture formats on the models are JPG, PNG and PGM files in 32-bit, 24-bit and 8-bit.
