What is a thermal mapping drone (TMD?)

Remote controlled quadcopter that will record and display a thermal image of the area that it has flown

over

4ECE Department

What’s already out there?

5ECE Department

What makes ours different?

Remote controlled (user friendly)• User can map a wide range of areas

Cost effective• Stitching multiple thermal images together

will allow a larger map to be generated without expensive equipment (i.e. satellites, high res thermal camera)

6ECE Department

Possible Applications

Homes Forests Oceans Search and Rescue Agriculture Glaciers

7ECE Department

Focus (Home Map)

Allow user to generate a thermal map of their home’s exterior

Data will be transmitted to and processed on their computer order to analyze IR sensor’s readings

Users can discover areas where heat escapes

8ECE Department

How significant is the problem?

In New England average winter cost of heating $1400 last year.

Expected to continue to rise 10-20% home energy wasted through leak

Requirement Analysis – Technical Specifications Stable flight using feedback controls for the Quadcopter

using Arduino microcontroller and 9 degree freedom sensor (that includes: accelerometer, gyroscope & magnetometer)

High Precision Infra-red Sensor MLX90620 that outputs temperature data in 16x4 pixel array

Data Transmission Via radio from IR-sensor mounted on the Drone to a receiver at the user’s GUI site

Web application with software to convert the data from the IR-sensor into a thermal map

13ECE Department

Design Alternatives

• GPS add on• Inter-Drone communication• Video camera• Programmable flight path
