New Feature: Ground Control Points

We’re happy to inform you that a new feature is available in airoCollect !   You can now use Ground Control Points to increase the accuracy of your models.


What are Ground Control Points ?

Ground Control Points (or GCPs) are points on the ground, inside your scanning area, with known coordinates.  A surveyor can measure their coordinates using for example accurate GNSS surveying equipment.

Ground Control Points can help airoCollect to generate a more accurate model.

For example, you can use them to get accurate coordinates from a scan with a DJI MINI drone. Or you can avoid scale errors in large projects.

When combined with an RTK drone (a drone with a centimeter accurate GNSS receiver on board)  you will increase the accuracy even more, especially in the ‘Z’ direction.

Drawing and measuring functionality

Basic functionality in airoCollect is being able to measure a terrain, a building, a roof, a garden, a road, …. . We provide measuring lines, circles, squares, polygons.
You can for instance measure the entire paved surface in a garden, or all the roads in a neighbourhood.

You can do this with the drawing tool:

You start with the color of the measurement that you’re about to do. For clarity reasons you can choose to do all of the same sort of surfaces in the same color. Grass green, asphalt grey, borders purple, … But that’s up to you. Choose the colours along the purpose of your measurements.

Then you pick one of the items:

  • Line: to measure a simple length
  • Polygon: for complex shapes
  • Squares
  • Circles

The other items are meant to make extra annotations on the ortophoto:

The next 4 items can be used to

  • Arrow: to point something out
  • Double arrow: to measure a distance between 2 points and make it more visible
  • Speech bubbles: to make something more clear with a remark
  • Images: to add images to the ortophoto

More clarity in your drawings and plans? Use layers. A tool to work on different plans in 1 project. For instance, if you have to work out 3 ideas and want to show this to your client.
