3D scanning may be riding on the coattails of 3D design and printing technologies, but it has had a long history of useful applications. For thousands of years, people have developed tools and skills to help replicate objects in the real world. Today, there are still many reasons to do 3D scanning. For example, the Innovation Lab, a community-driven solution space located in the Seminole Community Library at St. Petersburg College, has been working on some 3D scanning projects like digitizing real dinosaur bones to bring to schools and shared as holograms, helping a local glass museum import objects into virtual and augmented reality spaces, and more. In this webinar, Understand how 3D scanning works in a variety of industries, Learn about a variety of 3D scanners (software and hardware) currently on the market, Discover how 3D scanning can be used in libraries, museums, schools, and other institutions, Explore the future of 3D scanning and how it will enhance immersive technologies. Audio/Slides are available at https://floridalibrarywebinars.org/.

4. Types of 3D Scanning

5. Laser Scanning
Combines two sets of information to
create a point cloud of an object’s
surface: data from a laser being shone on
the object, and data from another sensor
(typically a moving camera, or two
stationary ones).
The scanning software stitches these data
sets together using the known distance
between the camera’s position and the
laser’s source to generate a model’s
points.

6. Stereo Vision and Photogrammetry
Stereo Vision creates a 3D model using images of an
object from two camera positions, mimicking the
stereo vision of human eyes.
Photogrammetry is the science of making
measurements from photographs. It adds more
camera positions to 3D capture objects. There is
Aerial Photogrammetry and Terrestrial and Close-
range Photogrammetry.

8. Structured Light Scanning
Source: https://bit.ly/2JhPgfs
One of the camera positions used in stereo vision and
laser scanning is replaced by a projector that projects
different light patterns (providing its own texture) onto
an object’s surface and recording how the object distorts
those patterns.
It is used in facial recognition technology, reverse
engineering, design, manufacturing, and remote
environment recognition (e.g., mapping the seafloor
railway tunnel inspections).

9. Time of Flight (ToF)
Source: https://bit.ly/2JhPgfs
Also known as laser pulse scanning. This technique
produces a 3D model scan by timing how long it
takes a laser’s beam to reach the object and
bounce off, traveling back to the laser’s source.
Fairly sophisticated and expensive.

36. 3D File Formats you may encounter while scanning
• .OBJ – Object file that includes 3D coordinates, texture maps, polygonal faces,
and other object information.
• .MTL – Material Template Library. Material settings are stored with an .OBJ file
and describes how textures are applied to the object. It includes the name of
texture bitmap files as well as the 3D positioning of the textures.
• .glTF (GL Transmission Format) is a file format for 3D scenes and models. It is
sometimes referred to as the "JPEG of 3D.“
• COLLADA (COLLAborative Design Activity) is an interchange file format for
interactive 3D applications.
• 3DS retains only the most basic information about geometry, appearance,
scene, and animation.
• VRML (Virtual Reality Modeling Language) files store 3D interactive vector
graphics, designed particularly for the WWW and/or color 3D prints.

48. 3D Scanning Issues
• Lighting must be bright and fairly consistent.
• Slight movements can make the scan look weird.
• Metallic/shiny, transparent, furry etc. objects are difficult to scan.
• If using entry level equipment, patience is key and you must have a
steady hand.
