• Driden model (?)

Crowd Analytics through Facial Recognition

Eyeris

Software package called ImoVu - Deep Learning architecture for image processes that imitates human recognition

• Vision for Embedded Systems
• 97% accurate
• 140 FPS on i7 processor
• Ambient Intelligence (AML) - Electronic environments that are sensitive and responsive to the presence of people.
• Minimal required resolution for a face: 50x50px, Ideal 70x70px
• Does not use FACS
• Uses OpenCV open source software to identify faces and for some devices, sometimes falls back to the devices facial recognition
• This software is not useful for things or places (only people)

• Allows for
  • Access to Hard to reach places
  • Large coverage area
  • Eye Level
  • Improved angles

• Trained For
  • 5 Major ethnic groups
  • 5 age groups
  • 2 genders
  • 10 lightning conditions
  • 13 head poses
  • supervised and unsupervised
  • different camera structures
  • different resolution
  • different face attributes
    • Joy
    • Surprise
    • Sadness
    • Disgust
    • Anger
    • Fear
    • Neutral

3D Mapping

• mark@visuallaw.com
• sketchfab - 3d modeling software
• pointcloud
• DroneDeploy - android app for creating 3d mesh and orthomap ($300 a month)
• Pix4D - the primary software for creating 3 modeling of terrain
• Adjisoft Photoscan (?) - Competitor to pix4d
• Autodesk is working on comparable software

Flying in Wind: State Estimation for UAS

• Douglas Weibel, PHD
• Wind - a vector velocity field with spatial and temporal variation
• Wind has structured (predictive) and random properties (turbulence) that are difficult to model
• State
  • Attitude (Roll, Pitch, Yaw, Roll Rate, Pitch Rate, Yaw Rate)
  • Attitude Rates
  • Position
  • Velocity
• Other possible states
  • Wind Paramters
  • Height over ground
  • Battery energy
  • gyro bias
  • accel bias
• Attitude Estimation
  • Stabilized Sub Platform
  • Whabba's problem
  • Integration
  • Combined
• Contempory Sensors
  • Gyros
  • Accelerometers
  • Magnetomers
  • GPS Baseline
  • Thermopile
  • Elecstratic potential
  • Opical sensors

• Federated Filter
• Attitude Filter ( Cascaded Filter )

Applications of Rotation Matrices and Matrix-Vector Algebra in Autopilots

Bill Premerlani

• A rotation matrix is a linear homegeneous transformation
• Tensor

FAA Regulations: Past, Present, and Future

• Jim Williams

• Drones are named from the first unmanned aircraft in Britain during WW1
• [1]
• FAA cant regulate anything congress doesn't give them authority over
• Required for an aircraft to be regulated
  • Approved Pilot
  • Aircraft Certificate
• Code of Federal Regulations (91.113) - you must be able to see and avoid other aircraft (thus-- you need a 333)
• COWA - Certificate of Waiver or Authorization
• AC - 91.57A new AC that regulates RC hobby
• AC's are not regulatory
• CFR 14 91.13 Careless and Reckless Operation
  • Aircraft operations for the purpose of air navigation. No person may operate an aircraft in a careless or reckless manner so as to endanger the life or property of another.
  • Don't do stupid things that put people in the air at risk.
• 14 CFR Part 107 creates new rules for small unmanned aircraft systems
• Examples
  • CNN is looking at tethered aircraft (tether provides power) - Power Electronics 01
  • Railroad wants UAV to monitor tracks in front of trains looking for issues with tracks
  • Farmers are looking for ways to safely use UAV without LOS by monitoring airspace for incoming commercial aircraft
• FAA - Department of Transportation interactions take a lot of time
