one of the reason why i hope i will not have to by a P4 pro but rather a H520 if the problems are solve....

you're welcome, you will easily find information on this subject on the Photoscan or Pix4d sites

Accurate georeferenced ground targets give you scale with a least centimeter precision. For your exemple, you will, for exemple, take mesureaments of some windows, you enter the mesureaments of 3 or more windows and the software will scale your model/orthophoto...

Yes it is possible with photogrammetry software. If the photos are georeferenced, you can already make measurements but with average margins of error of a few meters. Ideally, in order to have the most precision, ground targets are needed (Ground Control Points), which are then read by GNSS GPS...

all these probable problems with the E90 make me postpone a purchase of the h520. If there is a problem with the lenses, why not list the serial numbers and identify lots that would be defective?

@Dr Delta no mention because the C23 is the default camera for the H plus

From Yuneec France : C23 compatible with H Actualités - Yuneec

@Graham, i will take a look at 3DSurvey.

but if you do a survey mission, all the pictures are taken following straight lines at same height. If the terrain has different elevations, the drone should keep the same height to have the same GSD but that fonction is not a standard. In my memory, you can do that with Mission Planner...

@Graham As i have told you, some calibration should be done, every software has its procedures, I've tried your data with 2 differents softwares (Photoscan an Reality Capture) and i've the same result : a curve similar as fisheye from a GoPro : the pictures are not in a straight line and the...

Just has a quick note, Drone2Map from ESRI is based on Pix4DMapper technology. Unless you have ArcMap in your daily workflow it may not be the most attractive solution (Pix4D have a mounthly subscription, and you can work with QGis to vectorise data for example) About data, i use to work with a...

@gwhutoon Thanks for the info.

Hi, i want to know if anybody has info about the GPS unit? Is it a ublox Neo M8N or a T series where Raw data can be use for post process? About geo-tagging, is there an automate geotagging? Thanks

Hi, i am a drone pilot from France. I run a small mapping business since 2016. I started to be interested in drones in 2014 with a machine based on Pixhawk and now Solo. I'm interested in the H520 and I come to news ;)
