DroneDeploy Announces Improved Map Accuracy for senseFly eBee RTK
Use DroneDeploy to Process eBee RTK Imagery and Generate Maps to Within 3 cm Global Accuracy, comparable to Ground Control Points (GCPs)
Users of the senseFly eBee RTK drone now have a new option for processing their highly accurate geo-tagged eBee RTK imagery.
Thanks to a recent improvement in DroneDeploy’s image stitching algorithm, our Map Engine can now generate maps from eBee RTK images while maintaining 3 cm global accuracy. This improved accuracy, combined with a fast, affordable and easy-to-use cloud interface make DroneDeploy a natural choice for eBee RTK image processing and analysis.
When Precision Matters
Most drone maps provide a high degree of relative accuracy, meaning that the distances between points on the map are correct. For many map uses, including agricultural crop scouting, volume measurements and damage detection, this relative accuracy is more than sufficient. However, certain highly precise surveying and inspection operations require a high degree of global accuracy. This means making sure that each individual point within a map is geo-tagged to within a certain accuracy when compared to absolute, global latitude and longitude values — a difficult feat to achieve.
When drone operators need this high degree of global accuracy, they use one of two options for capturing data. The historical method uses Ground Control Points (GCPs), essentially marking big crosses in the area to be mapped that are visible to the aerial photography, measuring the absolute latitude and longitude of those points using a ground-based RTK GPS system, and manually entering these values into the map at the intersection of the crosses to correct the global positioning of the map.
The newer option is to use an eBee RTK drone, which includes an RTK GPS system and is able to achieve high global accuracy without the time-consuming use of GCPs.
Field Tests Demonstrate Accuracy
Civil Engineering firm Landpoint helped DroneDeploy test the new capability to process eBee RTK images. They mapped the same area three different ways and compared the global accuracy of the maps produced. One flight used a DJI Inspire drone without GCPs, one flight used a DJI Inspire drone with GCPs, and the third flight mapped the area with an eBee RTK. Landpoint found that the eBee RTK data processed with DroneDeploy’s updated image stitching algorithm had similar global accuracy (within 3 cm) as the map generated using GCPs.
Using DroneDeploy with Your ebee RTK Drone
Have an eBee RTK drone and want to try DroneDeploy? Just sign up for a DroneDeploy account and upload the imagery from your eBee RTK drone into DroneDeploy. Highly accurate RTK image processing is included on all plans (including our free tier), but you may want to explore our Pro or Precision plans (starting at $99/mo.) for additional advanced features like volume measurement and higher resolution maps.
