Alligning photos takes ages

[mskancke]

Hi

Hopefully not everyone has started their summer vacation yet.

I havent been working with photoscan for a while, but got a task to make a simple Georeferenced Orthophoto.

I fired up the drone and took around 800 photos of the area needed.


Ive started the allignment process, but it says its gonna take over 7 hours (its already been working for 24 hours)


Ive done this type of assignments before, with around the same amount of photos, but it never took more than 1 hour ish to allign the photos.


Im not working from my usuall station (its being repaired), so I took it into consideration when I gave the customer a timeframe, but I never thought it would take this long.

Im on a I7 gen 4 processor, so I really dont understand why its taking so long.
Taskmanager lists photoscan to be using 90-100% of processor capacity

Is it some bug in the new version?
Or have i missed something prior to starting the allignment?

Hello Marius,

Is it possible, that you started the alignment with disabled preselection? Also what were the limits for key and tie points?

Hi Alexey

Ye, my gut feeling was saying ive done something wrong with the settings prior to starting the task.

I aborted the job, and set preselection to referenced.

Its been so long since I worked with photoscan, so I dont remember the ideal settings anymore, so correct me if im wrong.

Accuracy: High
Preselection: Referenced (I have a logfile containing GCPs for all photos)
Max points 40000
Tie points 1000

Should I change the points value?

Hello Marius,

Looks fine, if there are coordinates for every camera position.
