Python and Java API / Importing camera calibration.xml (1.3.5) in PS 1.4

« on: February 13, 2018, 08:04:08 PM »

Hi there,

I've made a Camera calibration file in Photoscan lens in 1.3.5 and want to import this .xml file in Photoscan 1.4.0 via Python script.

this is my code:

PhotoScan.Calibration.load("G:\\BA\\agisoft_code\\Funktioniert\\Zusatz\\webcam_calib_16_9.xml", format=’xml’)

but it brings this error:
File "G:/BA/agisoft_code/AutoProcess_v2/calib.py", line 5
PhotoScan.Calibration.load("G:\\BA\\agisoft_code\\Funktioniert\\Zusatz\\webcam_calib_16_9.xml", format=’xml’)                                                                                                            ^
SyntaxError: invalid character in identifier
Error: invalid character in identifier (G:/BA/agisoft_code/AutoProcess_v2/calib.py, line 5)

Can someone help me? Is it even possible to import a .xml file of an older version?

thanks alot

Python and Java API / Basic skripting problems

« on: January 18, 2018, 01:29:19 PM »

Hello there,
I am not very experienced in programming or skripting but I need a skript which automates some steps in Photoscan.
The skript should import the pictures from a folder, detect marker, align the photos, generate a dense point cloud and import a csv-file in which the locations of the markers are saved.

Is it possible to create a skript which is able to do all the mentioned points?
What software do I need to create these skript?

Thank you for the advices!

General / Re: measuring and importing external camera orientations

Thank you for the response.

If I can't support Photoscan in the alignment process with the measured Camera coordinates,
how can I improve the alignment if you consider that i only have three pictures to work with?
(I take the pictures with an Panasonic DMC G5 on a tripod.)

General / measuring and importing external camera orientations

« on: December 07, 2017, 12:49:39 PM »

Hi everyone,

I'm trying to build a dense point cloud of a model with a limited number of pictures (three pictures).
In order to align the photos i want to measure the location and the orientation of the cameras.
The cameras are mounted on tripods and for measuring i can rely on a Faro Arm.

Now here is the question where is the origin of the z-axis of the camera coordinate system or to be precise where is the x-y-plane?
Is it on the sensor of the camera or is it on the the camera lens?

How can i import the camera data (external camera orientations parameters) so that i can define the origin of the model's coordinate system?
How do i have to measure the angles of the camera orientations relatively to the model's coordinate system?


Thank you for the advices.
