How Accurate is the Phantom 4 RTK?

Measurement Accuracy of the DJI Phantom 4 RTK & Photogrammetry



Over the past few years, unmanned aerial vehicles (UAVs) – more commonly known as drones – have increasingly become a popular tool for aerial data collection in construction, surveying, mining, and insurance. Utilizing photogrammetry, companies capture aerial imagery and generate valuable insights from large data sets, making it possible to see and measure the changes occurring over time on job sites, mines, and properties.

In this white paper, DroneDeploy investigates the ways to validate and improve the accuracy of photogrammetric maps with DJI’s Phantom 4 RTK (P4 RTK), a drone that applies RTK technology to aerial imagery. To test the accuracy of the P4 RTK, DroneDeploy created a control point system for a rooftop building survey. Then, 30+flights were logged – each exploring the effect of flight altitude, overlap, and number of images – and processed using DroneDeploy’s Map Engine. These datasets were then used to calculate both the horizontal and vertical accuracy of the measured points, along with the accuracy of linear measurements.
