Image Processing

VIP UHDT mission is to develop an autonomous Unmanned Aerial System that successfully performs all expected objectives of the annual AUVSI SUAS Competition to a higher degree than last year’s system.

Object Detection● Alphanumeric Recognition

○ Tensorflow ○ Convolutional Neural

Network○ 1 million training images

● Color Recognition○ OpenCV library○ Filter false positives○ Identify objects

Autonomous Geotagging● Image captured by the

UAS will be geographically tagged autonomously.

Interoperability● Receive mission details from

judge’s network● Collect data by telemetry● Submit data back to judges

● Modified LaTrax Dessert Prerunner● Electronics

○ uBlox GPS, Pixhawk 4 Mini, HolyBro Transceiver, and 3000 mAh NiMH 7C Battery

● Drop Box Mechanism ● Parachute Disengagement Mechanism● Weight: 1.13 kg

● Quad-Plane ○ Fixed wing aircraft with the ability

to vertically takeoff and land○ 2.72 kg payload capacity○ Carbon fiber and fiberglass

reinforced high density foam

● Autonomous takeoff via hand launch● UAV performs waypoint navigation● UAV drops UGV for air delivery

○ UGV autonomously drives to another specified coordinate upon landing

● UAV searches search area for targets or object detection and classification

● Autonomously land

● Electronics on Board○ Pixhawk 2○ Hero+ GPS○ Holybro 433MHz 500mW○ Raspberry Pi 3○ 5.8 GHz 200mW video

transmitter○ 915 MHz Crossfire Control

Link ○ Ubiquiti Bullet M5
