Note that the Canvas.io software really wants the latest iPhone or iPad devices with LIDAR scanners built-in. It will supposedly run on lesser hardware, but with greater error in the constructed 3D map.
Fine for a sample to get an idea of whether or not it might work for you, but not really enough to actually use for anything useful.
I was reminded about a program called MagicPlan. See https://youtu.be/gEUk7YzfTcc for a video demo of using it to scan an apartment, using an iPhone 12 Pro with the LIDAR sensor.
But IMO, this still isn’t good enough. It’s a huge improvement over the corner mode, which is what you have to use if you aren’t using a device with a LIDAR sensor, but it’s still not enough.
