Process failed: Task did not complete

[atomi]

Hi,

Many greets for everyone! I am a new newbie :)), just started to process ortomosaics in agriculture. I fly with Mavic 2 Pro (with Sentera Double 4k camera, but it is not important now) and having the following difficulties with the RGB (Hasselblad optic) picture processing.

Currently, I’ve sent two different jobs (projects) to the Lightning Network, and far as I see, they failed exectly the same way. Could you please take a look at them and provide me with some guidance?
Thank you in advance.

[Saijin_Naib]

Welcome!

Can you provide some details about how you performed your flight planning?

What app did you use?

What did you have set for your overlap and sidelap percentages? Did you stop for each photo?

[atomi]

The flight was planned by FieldAgent (Sentera) program. At take off it samples and sets the drone’s settings based on the environment and locks features. The drone do not stop when it takes pictures, but it has automatic focus lock when makes the shots. In this FieldAgent flight program you can only set overlap, which was set to 60% and 70% (project 1 and project 2). Altitude was at 60m, and speed at 5 m/s.

Thank you.

[Saijin_Naib]

Task 1:

Seems that overlap/sidelap are both far too low to reconstruct properly.

Task 2:
Not processed yet.

Does FieldAgent give you an idea of what the mission’s sidelap will be?

[atomi]

No, it does not. just the overlap

I tried the process on a different (5ha) area, and it worked out great.
Of course, it has less pictures and the overlap was set to 75%.

Thank you.

[Saijin_Naib]

How high does it let you set the overlap?

[atomi]

90%

[Saijin_Naib]

If you’ve got the storage, and the camera can write out that fast… Might as well, especially if it is going to keep sidelap so low.

Which way to orient camera?

Depends whether you’re more overlap or sidelap constrained. Most sensors are actually not square, but are close (3:2 being a typical CMOS sensor ratio). In the first image, you’ll have more overlap than you will sidelap. Why would you want this? If your sensor writes out slowly, orienting this way “buys” you slightly more pixels along your flightpath per exposure, which can be helpful in keeping your flight speed up. In the second image, you’ll have more sidelap than you will overlap. Why …

[atomi]

OK. Thank you
