Coddington, Nate Bellavia
Slide 2
Motivated by work done by Stanford PhD students RIT Prototype
developed during 2012- 2013 academic year by students in the
Freshman Imaging Project class Origins of project
Slide 3
Synthetic Aperture Imaging Reference: Marc Levoy
Slide 4
Basic Concept CamerasOccluder Object
Slide 5
What is a Multi-Camera Array?
Slide 6
Prototype Architecture Camera Image capture Mac Laptop Image
compression and resizing Computer Processing, control, storage
Arduino Trigger cameras x6 Switch Data routing User Interface
Select operating mode, initiate operation, render imagery
Slide 7
ImagineRIT Prototype
Slide 8
Increase frame rate of prototype by improving image processing
Develop and validate a predictive model to facilitate analysis of
alternate configurations Conduct cost/performance trade-off study
Summer Objectives
Slide 9
Matlab processing limitations o Handling of image display
Non-optimal data flow o Picture transfer from camera to software
Bottlenecks
Slide 10
Calibration Synthetic aperture through image shifting GUI
Components of the software
Slide 11
Matlab to C++ translation complete Result: 400% faster
processing o 16 frames per second Limitations: capture rate of
cameras Progress to date
Slide 12
Slide 13
remove remaining bottlenecks o File stream Software
optimization Next Steps
Slide 14
Increase frame rate of prototype by improving image processing
Develop and validate a predictive model to facilitate analysis of
alternate configurations Conduct cost/performance trade-off study
Summer Objectives
Slide 15
Predictive Model
Slide 16
Static Validation
Slide 17
Dynamic Validation
Slide 18
Alternate Configurations o Different cameras o Number of
cameras o Placement of cameras Model Applications
Slide 19
Point Grey cameras used in prototype cost ~$650 each Other
potential cameras available for a cost of ~$25 each Planning to
model and test system using Raspberry Pi cameras to determine
impact on image quality and frame rate Work currently in progress
Cost/Performance Tradeoffs
Slide 20
Demonstrated significantly improved performance by translating
processing routines Validated predictive model to allow rapid
assessment of alternate architectures Anticipate completing
cost/performance trade offs by end of summer Summary
