Drone Photogrammetry is the dimensional capture of objects in three-dimensional space using a drone with a gimbal mounted camera in the cargo bay. While there are some differences in the hardware, software, and data capture procedures utilized with Drone Photogrammetry, the most important distinction is its unit wide data capture capability.
Volumetric rapid data capture – capturing everything in the camera’s field of vision
Elimination of the "Line of Sight” obstacles
Not usable in low light conditions
High winds may be a problem
No off the shelf software or work process can provide connection level precision
Drone Flyover Example
For example: The most accurate measurement of a 150ft reactor head would include photos well above the 150ft elevation. Those angles and vantage points are rarely available when working with very large components. Drone based systems remove the “line of sight obstacle” that has plagued all industrial data capture in the past, providing opportunities to capture data that is impossible to capture with any other instrument.
