This course helps you discover what matters most to quality with unmanned aircraft systems (UAS) and computer vision (CV) projects. We will first discuss how the Drone/UAS and sensors affect map accuracy. Then we discuss the pitfalls of CV image processing. The proper spacing and location of ground control points (GCPs) will be discussed along with accuracy predictions. We propose that UAS mission “design” is a more thoughtful process than simply planning a mission to meet the required project accuracy. We present the typical deliverables from a UAS/CV project such as georeferenced images, orthophotos, three dimensional (3D) models, digital elevation models, digital terrain models and discuss the level of difficulty involved in producing these datasets. Producing these deliverables involves filtering and enhancing the data which may or may not improve your project accuracy. This discussion ends with a slightly more in depth look at the reasons for guidelines involving obvious “primary” variables and less obvious “secondary” variables that affect UAS/CV project accuracy.
Objectives:
- Discover what matters to UAS project accuracy
- Learn appropriate UAS mission planning requires a design process.
- Discuss ground control point design and spacing
- Learn the reasons for guidelines involving obvious “Primary” or less obvious “Secondary” variables that have an effect on the quality of UAS/CV data.
