DJI Zenmuse P1 test survey
How well does DJI’s new photogrammetry survey camera P1 perform on the Matrice 300? We had the chance to find out under challenging conditions. Surveying a landslide and road deformation.
First impression
– Workhorse
– large, sharp images
– Promising accuracy
In the air
We had the Matrice 300 with the new DJI Zenmuse P1 with 35mm lens available for one day. We had to fly manually with interval recording and ensure sufficient overlap. The base station was located in the survey area on a known point and provided RTK correction data.
Photogrammetry in pix4d
289 images from the 45MP Zenmuse P1 with RTK position data as baseline. Analysis in pix4d Mapper locally on our workstation. The known measuring points serve exclusively as control points.
Accuracy
The model was not optimized for control points (only check points used) to see what accuracy can be achieved purely via RTK. And the results of this first test flight look promising. Errors mostly below 2 cm on the control points. And this without a flight plan with defined overlap etc..
Collecting data for a landslide model with the Zenmuse P1
Our first personal impression of the Zenmuse P1 on the Matrice 300. Powerful tool with which excellent results can be achieved together with the D RTK Mobile Station on a known point.
Flight time of the Matrice 300 is great even with the large camera. Unfortunately, there was no time for a project with large areas this time, but the experience here puts us in a positive mood. The combination of high altitude and large batteries is a welcome addition to our toolbox.
Flight planning in DJI Pilot is getting better with every update, but some important features like simple terrain follow flight planning or corridor flights with tilted camera are unfortunately still missing. (@DJI is anyone reading this?).
High resolution for finest details oder efficient flight level. Global Shutter for photogrammetry.
High accuracy thanks to RTK and TimeSync 2.0
Intelligent oblique capturing with a turning gimbal. Better reconstruction of facades with only one flightplan.
The right lens for every project
We were able to test the DJI Zenmuse P1 with the Matrice 300 through the kind support of droneparts.de and the Ludwigsburg Surveying Office. Thank you guys!
