Is there a trick to scanning rooms using Canvas so that a typical square room comes out square with square corners and straight walls? I am using the wide view lens already. Most of the scans I take pick up a shift in perspective point that results in a “bending” of straight walls. After I scan up and down, move in a clockwise trajectory and finally come back to the starting point, the point does not end up in the same place: see pictures attached. Thanks for your help!
