speed / quality (idea)

Hello

Didnt found anything about:

The first time i tried the software the P3 was at 10m/s. That gave very blurry pictures and therefore renderings.

Then i tried with 5m/s. That is far better, but if you zoom in, the pictures are blurry (because of taking a picture during travel).

Idea:
Is it posible to travel with e.g. 10m/s but before taking the picture reduce the travel speed to 1m/s (or stop). Then the quality will be far better.

Here is an example:

There is certainly some blur there. There is only so much you can do with any camera...

The speed selected in the settings menu is the fastest the aircraft will fly. If you are flying low (< 60 m) we slow things down to make it so we can take images at the proper overlap while maintaining the maximum frame rate of 1 image every 2.5 seconds. It will gladly take images slower than that as prescribed by the overlap and speed.

Flying late in the day when there is not enough light generally doesn't work out well unless you know how to adjust the camera exposure compensation and speed. The camera

The DJI SDK only allows uploading 100 waypoints so they would get eaten up pretty quickly between the pass waypoints and the imaging.

If you are taking images in a low light situation our recommendation is don't do that, or adjust the speed down manually in the settings. We won't be adding a stopping at each image function because it would cover very little ground and can be done with the speed setting workaround.

sorry, is in the wrong section. can you correct please?

Thanks for your answer.

I know and understand the topics described.

I used the lowest possible speed in the Settings. The light was good in the afternoon (not too late, unfortunately no sun in Germany at this day and time). Normal pictures taken after the mission come out without problem or blur.

I wanted to fly at 36meters to get more details of the scene. Maybe that is the wrong thinking?

You can certainly fly lower. There is an Altitude slider override that enables it to go down to 25m if you hold the slider down (and stay very still) for 8 seconds or so.
We didn't want to enable super low flight by default because too many people would get crashy.

That would both slow you down and decrease your GSD so it might help.

Yes, i know that already that it is possible to fly low. I used 36m because there was a tree approx. 30m high (i checked that before). That was my reason i couldn't do a automated mission with your beta software with a lower height. I even will check if maybe a little bit higher will fix some of my problems (as advised in your other answer).

Also had this idea in mind !

Maybe the point is missed here. Slowing down before a shot will result in less blur no matter what height.

Can anything be done to do this?

As an update: The aircraft will now automatically select a speed that will prevent there from being too much ground smear due to low light conditions. It will be limited to 2 times the GSD which is common practice. The aircraft will be slowed automatically unless the "Slow Aircraft According to Light Conditions" setting is disabled. It is enabled by default.

It is not possible to slow down for each image since each pass is a set of waypoints and the speed will remain constant between those two points.
