The Arduino has long since proven itself to be one of the biggest boons to DIY heads since the soldering iron, but that doesn't mean it's not still able to impress, as amply demonstrated by this ...

On the hardware side is Structure, a mobile depth sensor that fits onto the back of an iPad that can be used to capture a 3D model of whatever is in front of it, including small and large objects ...

It also has some key improvements over the original 2013-era Structure sensor. A version of that model connected to the iPad , and offered an early look at where AR technology would head next.

Time-of-flight sensors work differently: by using the time-of-flight data to calculate how long it takes the lasers to reach the object, it’s getting real-time, 3D depth data instead of a 2D map ...
