Users Manual Ryan Stevenson Josh Kay Azim Mugtadir 2014 Abstract First responders law enforcement and military are tasked with entering dangerous often unknown environments on a daily basis Moreover many of these dangerous situations present environments with limited or no visibility Due to this lack of visibility the people entering these environments are less likely to gain an accurate understanding of their surroundings The IR Scout addresses these issues by performing remote thermal reconnaissance of hazardous environments The IR Scout is a highly durable sensor package that wirelessly transmits high guality thermal images to a remote user The system is composed of a throw able sensor package and a laptop that displays the thermal images The device reguires minimal user operation simply turn it on and throw it into the area of interest Once the sensor package reaches a stable position the appropriate cameras on the device each snap an infrared image and wirelessly transmit the data to a laptop The laptop then performs the necessary image processing to display multiple images neatly on the user interface With these features the IR Scout provides first responders with knowledge of a hazardous environment prior to entering regardless of visibility Final Specifications The IR Scout product consists of two main components the throwable device referred to as the IR Scout in this document and the user interface ref2. erred to as the IR Scout Application IR Scout Hardware The IR Scout consists of three camera boards would be 12 camera boards for a final product connected to a main board mounted in the center of the device The hardware that makes up these boards is documented below e Camera Boards O O O O Lepton Thermal Camera Linear Technology LTC 35945 IC 25 MHz crystal Oscillator Level Shifter e Main Board O O O O O Two 8 input MUXes ADXL 335 Analog Accelerometer Tiva C Launchpad Breakout Board TI Fuel Tank BoosterPack 3 7 V 1200 mAh Lithium lon Battery Main Board Stack Camera Board PCB Device Operation 1 Launch IR Scout Application a Launch MATLAB on your laptop and make sure that you have added the folder DemoDay to your current directory b Launch GUIDE by typing guide into the command line and once it launches select the tab that says Open Existing GUI x ax OC lt Student Version gt Command Window Student License for use in conjunction with courses offered at a degree granting institution Professional and commercial use prohibited Create New GUI o Si a Recently opened files 4 Users ryanstevenson Documents MATLAB capstone IRSCOUT LeptonGUl fig 4 Users ryanstevenson Documents MATLAB capstone IRSCOUT Lepton GUI F 4 Users ryanstevenson Documents MATLAB capstone IRSCOUT LeptonGul sir 4 Users ryanstevenson Documents MATLAB capstone IRSCOUT N
