Python and Java API / 360 Panorama creation using python

« on: January 26, 2021, 12:54:36 PM »

Hi,

I follow this tutorial and created 360 panorama from set of images.
https://www.agisoft.com/pdf/PS_1.1_Tutorial%20(IL)%20-%20Spherical%20panoramas%20generation.pdf

I would like to know whether it can be totally scripted using the python API?

Normally I am not using the 'Tasks' and use the 'chunks' api for customizing the processing.
The only missing part is couldn't find in the documentation is something like "chunk.exportPanorma"

Python and Java API / Match Photo Accuracy

« on: March 07, 2019, 05:36:09 PM »

Hi,

I was processing an 800 images project using python script with the HighestAccuracy.
The alignment process could align only small portion of the images (~100 images)

So I tried to re-process using  HighAccuracy and MediumAccuracy and got pretty much same results (partial alignment)

Only when degrade the accuracy into LowAccuracy the alignment was successful.

1. What could be the reason for the partial alignment? does the SW filter some tie points based on a certain threshold?
2. After getting a partial alignment in the first time, I would like to analyze the data and decide on the optimal accuracy value without trying all possible values and waste precious processing time. Is this possible?

Thanks!

Python and Java API / Camera Location Accuracy

« on: March 07, 2019, 05:13:38 PM »

Hi,

Does the accuracy value constrains the bundle adjustment to refine the camera location within the accuracy value range?

For example:
- Accuracy set to 0.1, will constrain the algorithm to refine the camera locations within 10CM from the initial value.
- Accuracy set to infinity, won't put any constrains for the bundle adjustment.

Correlator3D (another photogrammetry software) apply to this logic, this enable the user to apply 'direct geo-referencing' by limit the DoF.
