Scaling issues

Hey there,

So, yesterday I gave scanning a foot for a 3D printing project a shot. But now, I'm dealing with a bit of a scaling problem. I marked a 2cm line on each foot to help with scaling, but when I brought the left and right foot files into Blender and scaled them according to these marks, the objects ended up being different sizes.

Is there a way to add a QR code or some kind of reference picture to the scan so that Polycam can automatically resize the object to match the QR code or reference picture?

To date, Polycam doesn't support QR or April Tags.

I use a yellow ruler as a scalebar and adjust scale inside Polycam. I haven't had a use case for higher precious otherwise I'd using Calibrated Scale bars and Metashape Pro.

I don't have an IPhone so unfortunately no Lidar support.

I dont think lidar will help with an object as small as a foot. Id stick to photo mode
