P09561 – Visible Spectrum Imaging System: Project Update Dave Lewis Steve Sweet Joanna Dobeck Lenny Calabrese Jason Thibado Darrell Draper Customer: Dr. Carl Salvaggio; Imaging Science Department 1

Project Description Summary: Design and build an imaging system that can be mounted onto an Unmanned Aerial Vehicle and controlled with limited user input. This includes a high quality machine vision camera mounted on a vibration damping system, a frame grabber board to get images from the camera, a microcontroller to control the camera and manage storage, a power supply and a custom built frame to hold all equipment inside the plane. Customer: Imaging Science Department Key Customer Needs/ Engineering Specs – Camera System Modularity – Lightweight/ Compact – 4.5 x 3.7 x 7 in and 4.5 x 5 x 3.3 in, Under 5 pounds total weight – Autonomous image capture – Clear Images – Vibration isolation 2

System Architecture Camera VIS Power Microcontroller Storage Components Camera (Sony XCL-V500) Camera Interface (Camera Link) Microcontroller (PC104) Data Storage (SD Card) Power Mounting Frame Vibration Isolation System Camera Interface 3

Selected Concepts Aluminum Frame – Light weight, low cost, adequate strength 3 Axis Elastomer Vibration Isolation System – Low transmissibility, low natural frequency PC104 Microcontroller – Powerful, easily expandable, cost-effective Sony XCL-V500 – Efficient starting point for testing SD Card reader – Large storage available, cheap, longevity Lithium polymer batteries – High performance to cost ratio 4

Technical Risk Assessment Difficulty with PC104 programming and interfacing with the frame grabber and SD card. – Mitigation: Thorough research of PC104, Seek advice from people with PC104 experience. Crash of UAV damages current system – Mitigation: Thorough documentation will lead to ease of remanufacturing. Images Blurry – Mitigation: Increase aperture and decrease shutter speed. 5

Current State of Design Camera Controls and PowerVibration Isolation System 6

Current State of Design Current design meets customer needs On schedule with an aggressive schedule planned for SDII Budget – Production Cost: $3, – Allotted Budget: $ – Actual Cost: $1,

Key Milestones for MSD II Testing of camera, control and storage systems. (Week 4) Constructions of frame and vibration isolation system. (Week 5) 3 Axis vibration test on camera VIS. (Week 7) Tests on frame: Drop test, tensile and bending stresses on welded aluminum joints. (Week 7) Full system test (Week 8) 8
