Professional surveying and geo-mapping of the future are not fixed and static, but dynamic and flexible. With the Aibot X6 UAS (Unmanned Aerial System), a so called “drone”, you can generate data for orthophotos, 3D models, and point clouds in high density with great accuracy. In-house flight planning software makes it simple to obtain all the parameters essential for professional-class photogrammetry.

THE UAV SURVEYING WORKFLOW IS DEMONSTRATED IN SIX STEPS:
Step one – Preparation
During the drone surveying preparation phase, requirements are defined. A ground resolution of 1 mm to 4 mm per pixel is achieved. Parameters such as altitude, airspeed, overlap and distance between the trigger position, can quickly be achieved by using the Aibotix planning software, AiProFlight.
Step two – Flight planning
During step two, the survey flight plan is being created to capture the drone’s surveying data. Flight planning is done by using the Aibotix AiProFlight software. Flight direction, resolution, amount, route and stereo overlap are entered and displayed on the screen. The flight plan is then created and saved. Work orders such as camera position or dwell time can be changed at any time.
Step three – Control points
When surveyign with a drone ,we recommend setting up a checkpoint per hectare to achieve high accuracy geo-referencing. The reference points are set manually before the flight. This is only necessary if the survey requires a Cartesian coordinate system.
Step four – Flight operations
Once the surveying schedule has been uploaded onto the Aibot X6 UAV, data acquisition is completely automatic. Normal surface flight recordings are done at a 90°degree angle, with images taken oriented straight down to the surface, creating nadir. Unique to the Aibot X6 survey drone is the panning camera mount, which ensures flight within the mine, at an angle of up to 45° degrees. This oblique angle generates an otherwise unattainable detailed resolution of the side walls.
Step five – Geo-referencing images
The Geobox syncs the camera and the Aibot’s GPS system, storing the trigger point. The current GPS coordinates directly into the photo’s EXIF data, allowing processing of geo-referenced data in various GIS systems.
Step six – Orthophotos and 3D modelling
Create an image-based 3D model with softwares such as Agisoft Enso or by using the geo-referenced images to build the texture for the orthophoto or 3D model. Expensive camera calibrations are not required. The Agisoft Enso software performs a supplementary calibration by using the investigating camera parameters to the workflow.
