I solved the problem by inserting some GCPs not measured directly in the field but known from previous maps (edges of tanks and other unique elements never moved).
I was not able to insert the point with the precision of a colored marker on the ground but with a good approximation I scaled the...
Having already had a survey of the area, I was thinking of something like this.
Maybe I can impose a distance between two distant points to scale the image correctly.
I have been involved in drone photogrammetry for many years and I know how to operate.
The problem is that this time I can't physically measure GCPs on the ground.
However, since I don't need a survey that is precise or georeferenced, I wanted to understand how to obtain an "acceptable" result...
As the title says.
Unfortunately I only have a non-RTK P4 and this time I cannot access the ground to measure some GCPs with a total station (as I usually do).
The survey must NOT be georeferenced and must NOT be precise.
Furthermore, I already have a precise survey of the area and I just...
In recent months, drones with extremely advanced optics are coming out on the market.
In case of topographic surveys whose purpose is only to have a model to measure distances and calculate volumes (without the need for georeferencing) these drones can work without GCPs ?
I've downloaded the file "DJIFlightRecord_2021-XX-XX_[XX-XX-XX]" from the tablet.
The file is almost 3 Mb but is encrypted and no reader can convert it into something readable. How can I do ?
If I analyze the .csv file with these two methods no error message or anomaly appear.
I also decrypted the .dat file and I end up with an excel spreadsheet full of parameters and values. Can anyone help me figure out which column to check to understand if the gimbal had a problem or if there...
Just downloaded (and opened) both the .dat file from the drone and the .csv file from the tablet.
Where and what exactly should I look for in all those parameters and values ?
On Youtube I also found this video. Very similar to what happened to me. But the gimbal remained "stucked" until the...
Suddenly in the middle of a waypoint flight with Litchi, I noticed an initial "jolt" and a few seconds later the gimbal lost all control and began to tilt randomly following the force of the flight. On the tablet screen I noticed "Hardware Error". Upon landing, the gimbal was locked in an...
The 3 messages, including the one on the battery, continue to appear at the beginning of each flight (then disappear after a few seconds.)
The warnings only appear if I use Litchi. If I use the official DJI GO app, no anomalies are reported. Even if I connect the drone to DJI Assistant, no...
No. The message continues to appear with the drone perfectly stationary on an even surface and with fine GPS count.
No. The message continues to appear while I wait for the IMU to initialize, without doing anything.
No. Battery is firmly clicked.
I have been flying for about 5 years and this...
