blurry photos

El error está en la aplicación. Como te dije, he realizado muchos vuelos con negocios de piloto de mapas y ni una sola vez recopilé fotos mal enfocadas.
Con la aplicación Map pliot pro he realizado dos misiones, de hecho es la misma repetida, a una altitud de 90 metros, por lo que el enfoque es más fácil, y en ambas ocasiones he tenido fotos muy borrosas

We can only respond to support requests that are made in English. 

If you are having trouble getting consistent focus results we highly suggest using the Manual Focus setting. We have zero control of the focus that the camera provides. We stop the aircraft. Point it downwards. And tell it to take an autofocus. If the value is bad we can't do anything about that which is why we make it so you can redo it or use the manual value.

Can you explain to me why the Map Pilot Bussines application always got a good value from the focus, and the Map Pilot Pro application does not get it, knowing that I am using the same drone.

Map Pilot Pro and Map Pilot Business do no focus the camera. They tell the camera to focus itself based on what it is looking at. There is no difference. It is likely that the spot that it is taking the autofocus reading is what is causing the issue. It would do it with Map Pilot Business too. This is like a site specific problem which is why we made the recommendations we made previously.

There are two variables for you, the location you are taking off from and the app. The app telling the the camera to do the focus. So since your camera is the same the only variable is the takeoff location. This is not an uncommon issue. It occurred frequently with Map Pilot Business which is why we added the extra manual focus control for Map Pilot Pro. 

I will follow your recommendation on the next mission. I'll keep you informed.
Thanks

My license is basic. Previously had the bussines. I paid 50 dollars for this new one.
I've been looking and it doesn't have the manual focus option.
As I have told you, with the bussines version, all the flight missions collected well-focused photos, and with this new app, more than half of the time the photos are very out of focus.
What solution do you offer me?
I am the same person, I have entered with another email

Manual Focus is part of the Pro tier of advanced features. If you can't use manual focus you will need to pay close attention to what the Autofocus is doing and make sure it is happening over a location that will give a good solution. Again, this is not an issue with the app. It is just how the camera is pulling the autofocus. As noted in the link above you can stop the mission at any time and redo the autofocus if you don't think it is correct. You really don't want to have the camera pointed at anything that is moving when you do the autofocus since it uses sequential images for contrast measurements and and motion could throw it off. 

I can't tell if the photos have contrast until I download them and check them on the laptop screen by zooming in or passing the Metashape Agisoft quality filter.
What I know for sure is that of the 11 batteries that I have flown with the new app, 7 of those flights were very unfocused.
If you tell me an email address, I can send you the photos so you can see them

The area where I have made these flights is a field of fruit trees, without people, vehicles, or anything moving. In addition, the flight height has been 90 meters, which would give an almost perfect focus.

There is no reason being at 90 meters should give perfect focus. That doesn't mean anything. As you have proven, focus can be bad up high too. You never really answered the questions about the ground smear values. This whole thing could be motion related, not focus. You could potentially use the infinity setting since you are high up. 

Doing autofocus over trees is likely the issue and why you didn't have the same issue previously. Trees are almost always in motion and the camera does a bad job rendering green to begin with. 

Do your autofocus over an area that has fixed solid objects that are contrasty. Flat stuff like sand or snow is bad. Normal exposed earth is good. Grass isn't great but is better than trees. 

Today I have flown a small mission of little more than one hectare, in an area with little unevenness.
First, I have flown it with a map pilot bussines without a digital terrain model at a constant 30 meters from the take-off area. The photos have all been of good quality, between 0.8 and 0.95, according to the quality estimate of Metashape Agisoft.
Then I flew the same mission with map pilot pro and the same drone, a phatom 4 advance, with terrain overlap at 30 meters high. Photos are out of focus, with a value between 0.5 and 0.65.
I can send you today's and tomorrow's papers. The map pilot pro version does not work well, the drone flies perfect but the photos are not useful for photogrammetry work.

Is there a way to manually load a digital model in my version map pilot bussines ?. your new application does not work for me. At least I could keep flying with the old app until they fix this huge problem.

You STILL haven't answered about the differences in speed. Please upload all of your log files so we can see what is going on.

There is no way to work with terrain data that isn't already downloaded to your device with the old version of the app. 

give me an email address where to send the download links of the photos

We don't need the photos. We need the log files for the two flights you are comparing. If you sync them to Maps Made Easy we can inspect them. 

Do you have access to all my synchronized flights without my authorization?

Well, they are on my account. on October 30, with 5 batteries, more than a thousand photos are out of focus of a total of 1900

Just the ones you have synced since you have the 'Flight Sync' enabled in the settings. It is there to help you with support in cases like this and for your own review and compliance.

That being said, October 30 is in about 4 weeks. There are no flight logs available for review since October 1. We can't really help you without seeing all of the flight logs you are talking about. 

Sorry. The flight date I want you to check is Thursday, September 30, 2021.

Hi Zane,

I am using P4 Adv and latest MapPilot Pro (Base Level).

Today I had a focus fail and unfortunately didn't see the message "focus failed" so I let the mission continue. I took off dirt and that's possible the cause of the bad focus. The photos are blurry and metashape rates them as 0.63 to 0.75 quality.

Can these blurry photos be used in photogrammetry or the results will be unacceptable for orthophoto and DEM production?

You did not see the error message in focus because there was no such message. Those photos you can use, but the quality of your work will be very low

This was my first time that the camera went out of focus.

I remember seeing the "focus success" message in most missions after the take off. Today I maybe I wasn't looking at the ipad screen but I can't tell for sure.

Anyway if it is possible can you add the "focus failure" message to the aircraft errors panel? It could be useful.

There is a popup that says "Focus Success" or "Focus Failure" at the top of the climb when the autofocus is done. "Focus Failure" means that the camera was unable to determine a suitable autofocus solution in the area of interest. If it says 'Focus Success' that means the camera was able to calculate a solution. Even in this case it doesn't mean the focus is guaranteed to be good. It just means it optimized for whatever it was looking at successfully. If what it was looking at (objects noted above) wasn't a good AF target it will succeed but still be bad. Again, we have no control over this. We tell the camera to autofocus and it says whether it did it or not. The only thing you, the pilot, can control is when it is redone.

The failure could probably go into the aircraft errors panel in a future release. 

Are you reviewing the flight that I indicated to tell me what could have happened?

BTW I used the blurry photos in a metashape project and despite the blurriness the result came very decent. I had 5-10cm elevation error in my checkpoints. Hopefully before the mission I took some manual photos of the site and they helped a lot! 

I can see the flight. Are the out of focus images all in one section or are they spread throughout?  

Most of your flights had ground smear of 1.5-2 cm, which is pretty good. But one of the flights got up to 3-4cm.

Another thing to keep in mind is that most DJI cameras are notoriously bad at rendering greens. Zoom in on the raw images and see. I don't know how the score you are looking at is generated but it might be an issue there. 

Have you reviewed the images I have sent you? have you found any answer?

Nothing can be done to fix images that have already been collected. There is a lot of discussion here on what you need to do going forward to ensure quality focus. 

Hi Zane,

I would like to report an issue about focus.

Today I had a flight and it went very good. I saw the message "focus success" and let the mission finish. The photos were very good and in focus.

However in AirData Notifications page reports "Setting Focus failed". Is this some bug?

Here is the airdata link to check.

Thanks in advance.

The version 5.1.3 has some focus related fixes. It won't change the function of the autofocus but it will allow the user to see the value the Autofocus pulls to see if it makes sense. 

If you saw the Focus Success message then it was good. There is apparently a bug in what gets written to the log file. That will be addressed in the next release.
