Surveying & Mapping
Accomplishing demanding survey projects with the Aibot X6 surveying UAV.
Aerial surveying and geo-mapping with an UAV
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), 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 parametres essential for professional-class photogrammetry.
Wide range of applications for the Aibot X6 hexacopter:
• Survey of challenging sites such as quarries, sand pits, landfills, coal stockpiles, etc.
• Point cloud generation
• Volume calculation
• GM creation
• Creation of location and inventory plans
• Creation of topographic images
• Creation of planning fundamentals
• Documentation of construction progress
• Inner-city survey
• Aerial photographs
• Inspection tasks
Your advantages of using the Aibot X6 UAV:
• You can go places that conventional equipment cannot reach.
• You increase safety for your surveying staff.
• You save time and costs using a surveying UAV.
• You get high quality, accurate results.
• You benefit from the high level of expertise, the synergies, and the innovation potential of Hexagon businesses.
• You will receive a premium product made in Germany.
The UAV surveying workflow is demonstrated below in six steps:
Step 1: Preparation
During the UAV surveying preparation phase, requirements are defined. A ground resolution of 1 mm to 4 mm per pixel is achieved. Parametres, such as atitude, airspeed, overlap and distance between the trigger position, can quickly be achieved by using the Aibotix planning software, AiProFlight.
Step 2: Planning the survey flight
During step two, the survey flight plan is being created to capture the UAV'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 3: Control points
When surveying with an UAV, 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 4: 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 UAV 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 5: Geo-referencing images
The Geobox syncs the camera and the Aibot's GPS system, storing the trigger point. The current GP coordinates are directly put into the photo's EXIF data, allowing processing of geo-referenced data in various GIS systems.
Step 6: 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.
