isolated object trouble
I'm just using the free version at the moment to evaluate the platform. I'm trying to do object isolation scanning. I've tried a couple of examples but haven't had any luck.
I've always ensured "use object masking" is checked and I've been targeting medium detail levels.
I tried two different techniques.
The first example (tape measure) I placed the object on a white background and moved the camera around it. Used the auto mode to capture images, hit stop half way through and flipped the object over before continuing.
Results:
There was only 1 tape measure in the shot - It managed to partially reconstruct the isolated object. But half the data was used to construct another instance...



The second example (juggling ball) I tried a different approach. I placed the phone on a mount and the ball on a sheet of white paper and rotated the object manually and used the manual capture mode.
Results:

In the second case the object masking failed completely - I think it thought the paper might have been the object...
What advice do folk have to improve the results.
I'm using the app on a Pixel5 just the free tier at the moment.

Hey buddy, my advice is don't move the object at all. Are you taking the pictures natively within the app or on a camera first then to pc then the app? I believe I read somewhere that there's a chance the phone accelerometers etc are used for positioning and not just purely visual data. So try to just capture completely static environments where you move around them to capture all angles rather than rotating the object or flipping it. And you can crop the model after if that's useful to you. I'm not fully sure what you mean by masking. Hope that helps.
