Choosing the right tools
- When choosing the right tools for a capture or documentation project, there are a few items you may want to consider when you're executing reality capture. The environment, is it wet? Is it raining outside, or is it dry and extremely hot? Is it indoors, outdoors? Is there repeating geometry of the subject matter? Is the area to be captured very large and open or small and confined? These factors can determine whether you use 3D laser scanning or photogrammetry. For example, photogrammetry uses a sequence of photos to reconstruct a 3D representation of a place or object, while 3D laser scanning by its very nature uses an emitted light source, a laser, which depending on the wavelength of the laser may not be able to return information off of water or wet areas. Therefore, it's essential to know your equipment operating parameters and to understand that your environment can have adverse effects on your data.…
