ONav and GeoPixel™ Web-Based Navigation for the Collection of Aerial Imagery

摘要

ONav is a heads-up navigation display for pilots for coastal imagery acquisition. The system is built on the Linux operating system (Debian) and utilizes a number of open-source tools and data sources. The system combines a real-time Global Positioning System (GPS) and inertial measurement unit (IMU) stream, along with image collection metadata from the onboard cameras to generate vector overlays the pilots can use to easily navigate, track progress, and ensure full coverage of the survey area. This technique has vastly improved the efficiency with which images can be collected.
