Drones

DRONES

Drones

Uses for Drones in Design / Construction1. Photo / Video documentation of large

areas2. Ability to view tall or difficult to access

structures (tanks, towers, etc.) 3. Can be outfitted with special cameras

(LiDar, Infrared, etc.)

360° Cameras

360° CAMERAS

360° Cameras

Advantages of 360 Cameras:1. Ability to pan around (similar to Google

Street View)2. Can document large area in a single

photo (reduces number of photos)3. Creates efficiency by reducing time to

photograph a site

3D Laser Scanning

3D LASER SCANNING

3D Laser Scanning

What is 3D Laser Scanning?1. Collects up to 50,000 points per second.2. Most scans take 4 to 10 minutes3. Can combine multiple instrument setups

to create 3D model4. Accuracy of each point can be 6mm or

better (< ¼”) depending on scanner5. Can be combined with 360 photographs

to provide photo-realistic 3D model6. Can be imported into various software

packages, including AutoCAD

3D Laser Scanning

Advantages:1. Higher resolution (more points) than

traditional surveying2. Fast scan time = labor savings3. Collects everything within field of view

(minimizes additional trips)4. Can scan difficult to reach features

(inside deep tanks, high ceilings, across inaccessible paths)

3D Laser Scanning

Disadvantages:1. Large file sizes (GB’s of data instead of

MB’s)2. Limited to field of view (shadow effect)3. Some learning curve to make data

useable format for design

3D Modeling

3D MODELING

3D Modeling

Design Phase1. Stakeholder buy-in (conceptual designs)2. Can be used to generate 2D drawings3. Spec driven design4. Conflict detection

Construction Phase1. Constructability review2. Obtain additional detailed dimensions3. Building Information Modeling (BIM)

Virtual / Augmented Reality

VIRTUAL / AUGMENTED REALITY

Virtual / Augmented Reality

Definitions:

Virtual Reality: an artificial environment which is experienced through sensory stimuli (as sights and sounds) provided by a computer and in which one's actions partially determine what happens in the environment

Virtual / Augmented Reality

Virtual / Augmented Reality

Definitions:

Augmented Reality: an enhanced version of reality created by the use of technology to overlay digital information on an image of something being viewed through a device (such as a smartphone camera)
