Building an Orthomosaic from Raw Drone Photos
Understanding the raw material Raw drone photos are a pile of separate images, each shot from a slightly different angle and position. They contain the data you need, but they are not a map. An orthomosaic is a single, geometrically corrected composite image that behaves like a map: every pixel corresponds to a real-world coordinate, and distances can be measured accurately. Getting there requires a sequence of processing steps, and each one has its own pitfalls. Step 1: C
