Current Drone Surveys

• You see a lot of fixed wings (planes) covering farms and forests

• Flying relatively high and fast (planes have a high minimum stall speed)

• Great for covering lots of area because they move so fast

• Basically 2D with some ability to extract 3D information

The Problem• What if you need to cover a smaller volume in

much greater detail?

• What if you want to use special sensors that require slower flight?

• What if you need to map 3D features such as cliff sides, caves, lava tubes, sinkholes, forest canopy structures?

• What if you want to monitor the same spot over and over at altitude?

Hovering VTOL Drones

• Copters / multirotors

• Able to cover 3D volumes with precise flight control

• Able to move at a speed you dictate— no minimum stall speed

• Many sizes/payloads

3D Mapping

Precise 3D flight control

+ S.L.A.M.

+ New lightweight sensors

= Real-time 3D mapping

SLAM:Simultaneous Localization and

Mapping• Real-time mapping

of the drone’s environment

• Can be used for collision avoidance without a priori knowledge of the environment

• Indoors: Visible+IR (Kinect), Outdoors: Sonar, Lidar, SFM

Page 9: 3D Drone Surveying

Google self-driving car uses SLAM with LIDAR and CV

Page 10: 3D Drone Surveying

Alternative SensorsTake advantage of flying low and slow

Page 11: 3D Drone Surveying

Acoustic Mapping• Flying low and slow

means you can record & map sounds

• Copter acoustic signature is fairly consistent (~4kHz), easy to filter out

• Recurring population surveys

Page 12: 3D Drone Surveying

Air Sampling• Samples of air from

specific altitudes with timestamps, temp, pressure, humidity…

• Gases (e.g. SOx, NOx)

• Microorganisms

• Realtime analysis or sample and analyze later

Page 13: 3D Drone Surveying

Radiation Sampling• Fly compact geiger counters over

dynamically changing landscapes

• Monitor EMF signatures at the same time

Virtual Observation

TowerDeploy a variable-height

observation platform wherever you need it

A Tower Where You Need It

• Dronehaus monitoring stations could be deployed anywhere
