Advantages and Disadvantages of 3D Laser Scanners

Application of 3D Scanner

Advantages of 3D scanning
3D scanning is a significant technology not just for re-creating objects or designing models for 3D printing, but also for many other applications.
3D scanning can preserve ancient art and protect it from damage due to wars. It can also be of tremendous value in areas like health care where a fractured skull can be rebuilt using 3D scanned models or prosthetics can be custom made.
Even animated movies and special effects are created with 3D scanning. Automotive and aeronautics industries use 3D scanning to create models and designs. 3D scanning brings closer the real world and the digital world and lowers the boundary between the two.
Real estate and tourism are other exciting areas of application for 3D scanning. Buildings can be scanned and shown to clients remotely as part of a virtual tour. A tourist area can also be scanned and re-created in a virtual reality form.
Various 3D scanning technologies are available today. Each technology has its own advantages and disadvantages. Depending upon the type of object (or person) being scanned and the type of environment in which the object is placed, the appropriate 3D scanning technology is used.
Laser scanner limitations/disadvantages
  1. Visibility, (direct, cone of visibility)
  2. Color (Black, pure color)
  3. Material (reflective, transparent and semitransparent, peculiar BRDFs), GOLD, AND SILVER Difficult to scan.
  4. Acquisition environment (temperature, illumination, crowded places)
  5. Size Vs. Single map acquired (accumulation of alignment error)
  6. Non-rigid stuff
