1 Senior Design Project 2009 – Team Goeckel PAWS Precise Autonomous Wildlife Surveillance Outline Motivation Requirements Design Prototype Outlook Application Requirements System Specifications Competitors Block Diagram Timeline MDR Specifications

2 2 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel Contemporary Societal Context  Environmental Concerns Sprawling human infrastructure and influence reducing wildlife habitats worldwide Wildlife at risk of extinction  Political Context Government protection under Endangered Species Act needed to preserve rare species Considerable data is needed to support a claim for government protection

3 3 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel Examples Thought to be extinct Recently rediscovered by wildlife camera Application for protection under Endangered Species Act California Wolverine Rare tiger photographed on Sumatra Photos used to estimate population density and establish range maps “Camera Traps.” worldwildlife.org. 8 October Cambodian Tiger Hunted to near extinction Efforts being made to protect natural populations Asiatic Cheetahs Fewer than 60 exist on the entire Asian continent was filed based on new evidence

4 4 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel Examples Clouded Leopard Sumatran Tiger Asian Elephants Rare species found deep in Sumatran Forest Forest earmarked for oil palm and timber plantations Area of forest where pictures taken deemed “worthless” by local government

5 5 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel Potential Consumers  Conservationist Organizations seeking government protection for rare species Monitor movements and migratory patterns Evidence and data to support or discredit claims for endangered species classification  Wildlife Documentaries Rare footage Motion tracking will allow for higher quality video  Wildlife Scientists Involved in various studies necessitating wildlife surveillance

6 6 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel A pplication Requirements (details in subsequent slides)  Cost  Main competitor-camera traps ~$700  Environmental Conditions  Outdoor application  Noise  Sensitivities of wildlife must be considered  Pan Speed  Trade-off between capturing at average speed or slower speed  Resolution / Frame Rate  Ability to identify distinguishable features in targeted wildlife  Maximizing data throughput and minimizing tracking delay

7 7 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel Applying Realistic Constraints  Noise Tested for noise levels and evaluated to be within a, yet to be determined, permissible audible range.  Environment Components can withstand ºC and Humidity range % RH (non-condensing) Optional system case will extend operability ranges  Cost Prototype is within cost specification (excluding computer) Cost will be variable on account of the range of cameras and quality available

8 8 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel Applying Realistic Constraints- Experimentation  Vision Range 360 Degrees Lateral Pan Angle of View from Camera 48 ○ horizontal 30 ○ vertical At 15 feet allows you to see 12 feet up a tree  Pan Speed Given a target moving 20 mph at 15 feet, Angular Velocity 111 Degrees/sec  3.24s / revolution Servo chosen to meet application requirement RECALL: NOT tracking animals at top speeds  Power Currently a computer is being used for computing and the source of power- FPGA in the future? 2 week sustainability is the goal

9 9 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel Flow Diagram Deployment of PAWS (Wait for Motion) MCU Position Adjustment Algorithm Recording Video Motion Vector Analysis Servo with Camera Images Storage Sensor Detection? Target Relocated? No Target Located End Video Return to Dormant State data No Yes Time Out PWM No Yes

10 10 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel Block Diagram Camera Servo High Powered Microprocessor Image Processor Memory Serial MCU Motion Sensor Array PWM Ethernet

11 11 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel  Original MDR Specs Camera, Servo, MCU, & Motion Sensors Interfaced Identify quadrants w/ motion sensors and move servo accordingly Successfully track an simple object against a simple background Prototype  MDR Progress 3 major interfaces completed Established basis for extracting pixels and identifying the center of a target object

12 12 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel Motion Sensor Array to MCU Signal out of Sensor High and Low Strobe while detecting motion Charging CapacitorDischarging Capacitor Capacitor is chargingCapacitor discharging when motion is detected. Complete discharge will initiate system. Time Constant is adjustable using a potentiometer for the resistor in the RC Circuit. Adjusting τ adjusts the sensitivity level of the system.

13 13 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel MCU to Servo  Each duty cycle corresponds to a discrete location  Using Servo library in MCU, Pulse Width Modulation generated Duty Cycle Period Duty Cycle -.9 ms Duty Cycle – 1.5 ms Duty Cycle – 1.2 ms Duty Cycle – 1.8 ms 180 ° 90 ° 270 ° 0 °

14 14 Motivation Application Requirements System Specifications Design Prototype Outlook Senior Design Project 2009 – Team Goeckel MCU to Servo Frames Isolation of a Target Center of Target
