![Page 2: Droneflow - cdn.ymaws.com · 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](https://reader033.vdocument.in/reader033/viewer/2022051915/60072a037b74140353550c09/html5/thumbnails/2.jpg)
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 prioriknowledge of the environment
• Indoors: Visible+IR (Kinect), Outdoors: Sonar, Lidar, SFM

Google self-driving car uses SLAM with LIDAR and CV

Alternative SensorsTake advantage of flying low and slow

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

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

Radiation Sampling• Fly compact geiger counters over
dynamically changing landscapes
• Monitor EMF signatures at the same time
