if you are digitizing a building you can use cameras from multiple views. There used to be a company that sold software to do that and there was a freeware version.
If you need accuracy, there are 3d laser scanners. Most of the architectural scale scanners are expensive enough that you would have to pay someone to do it. Structured light is always an option.
If it is something the size of a single family residence, you can use a Sick LMS200 laser scanner and rotate it. Still talking about at least 5k and a considerable amount of software.
In the U.S., paranoia has gripped our country to the extent that taking pictures of buildings has become a highly suspicious activity. You should keep that in mind if it's not your building. |
