A margin of error of 13.8cm in current 3D scans of human bodies? I think their baseline is bogusly large.

- changoplatanero 5y agoYes that seems too big to be true
- yorwba 5y agoThey're using a commercial scanner: https://www.sizestream.com/technology https://www.sizestream.com/technology The margin of error is less surprising if you consider that they're interested in the precision of measurements like hinged upper bust circumference, not the position of raw points in a point cloud. According to the paper "Erroneous measurements occur because of the 3 D Body Scanner’s incorrect placement of anthropometric landmarks or the physical positioning of body parts which increase measurement paths against the algorithms. The 3 D Body Scanner’s incorrect landmark and measurement placement, in this study, causes measurements with a range of up to 32.9 cm (M=14.6 cm; SD=12.67 cm)." I.e. if the scanner confuses your arm for your leg, that's going to throw off the measurements a lot. It seems like SizeStream could easily improve their product by applying some basic filtering to remove outliers.
- tapland 5y agoOh yeah. And a grainy surface would give a higher surface area which if you used that as a measurement for creating clothes would be bad, but less bad with improved surface measurements.
