Does anyone have direct experience with Occipital's low cost Structure Sensor and Canvas app for iPad?
A friend just pointed me to the Canvas web site:
https://canvas.io
which is a free iPad app (for high power iPads) using the Structure Sensor which is now also owned/made by Occipital. (I dug in and found an earlier version of this was produced by 3D Systems.) Cost is around $400.
This is a 2 camera visual scan that they claim gives accuracy within 1-2%, good enough for rough context for a remodel. Various images/videos on the site.
I downloaded one of the SketchUp models - a scan mesh (they don't create point clouds) can be converted to SU for $29. It cleanly converted to properly grouped ARCHICAD Morphs - windows distinct from walls, e.g. - but the accuracy of elements such as windows, cabinet toe-kicks, etc suggested to me that it was created by manual labor - no doubt somewhere in the world at super low labor rates. I'm a little ethically concerned that Occipital/Canvas doesn't address this likely human factor - or the working conditions for the employees. Anyone know more?
Site shows how accuracy varies based on distance from the iPad because of the way 2-camera depth sensing works. Press release from this fall lists that they bought a LiDAR company to provide more accurate laser measurement solutions as well. Video gives a quick overview of Canvas/Structure Sensor vs Paracosm LiDAR:
Anyway... any feedback on anyone's experience with Occipital/Canvas appreciated. I'm feeling really tempted for a remodel project coming up...
Thanks,
Karl
