Pollefeys' running group already developed a three-D scanner
for smartphones two years in the past. This changed into meant for smaller
gadgets. The present day project allows even entire homes to be mapped for the
primary time, thanks to the fisheye lens and the tool's high processing
strength. "In future, this can likely even be used to survey entire
districts," says Sattler.
As the researchers have located, the mapping of huge objects
is plagued by way of calculation errors in respect of the three-D coordinates.
"It isn't that smooth to differentiate among correct and incorrect
information," explains Sattler. "We solved the problem by means of
programming the software program to scrupulously delete all dubious
values." actual-time feedback is important to ensuring that the 3D version
does no longer emerge as a patchwork. way to a preview mode the consumer always
is aware of for which building areas they have collected enough statistics and
which still require scanning.
