What sensor should I buy?
Each sensor has its pro and cons. If you are an occasional user on a budget, and do not plan to scan for commercial applications, then Kinect for Xbox is the cheapest alternative. Kinect for Windows has better driver support, can be used for commercial applications and has a growing list of additional features (gain control, near mode, etc.). If you don’t need a motor and would like a device without an external power supply, then the Asus Xtion Pro Live or Primesense Carmine 08 is a good alternative. For close range applications (35cm – 2 meters), the Primesense Carmine 09 is the best choice, with lower minimal distance and more precision. For wireless mobility and high-quality color texturing, we recommend using the new Structure Sensor using Uplink in conjunction with an Apple iPad.
