Our Idea

-Implementation of technology into warfare in order to provide benefits to soldiers

Objective •To create a device that quickly and accurately scans

the area behind a soldier for potential threats

• To create a device that is affordable and simple enough that it can easily be distributed to all necessary armed personal in the military

• Reduce the chances of a soldier being caught off guard

Functionality

• Gather Infrared Readings

• Process Image to detect Threats

• Notify Soldier of possible Threats

Software Flow Chart• Gather Infrared Readings• Is above ambient

temperature?• Isolate high temperature

area• Determine if object is

human• Notify Soldier of possible

Threats

Technical Design

Thermal Imaging

• Detect Infrared Heat Sources

• Uncooled vs Cooled Devices

• Utilizing LWIR with SWIR to eliminate thermal crossover

Thermal Sensing Element

• LWIR with possible use of SWIR

• Thermal camera producing an analog video signal

• Needs to be durable, reliable, and accurate

• Possible Choices:– PICO640 LWIR with SU1024LDM– Thermopiles

Microprocessor

• Sufficient memory• Fast enough• Affordable• Simple to program• ATMega from AVR

Output Device

• Wireless headset• Secure communication

area around the soldier• FreeMotion 200 Wireless

headset

Principles

• Extensive research currently occurring in thermal imagining

• Image processing methods to find people in an image

• Human robot interaction falls within the scope of our project

Evaluation

• Speed and accuracy - no guarantee it will always detect a

threat• Ethical concerns (soldier dependency)

Future Possibilities

• Create everything ourselves• Add more sensors
