Lens calibration not working
« on: March 13, 2017, 01:38:40 AM »
Hello,

I'm trying to calibrate several camera/lens combos (estimate f,c,K,P parameters) that I will be using to take images for photoscan projects. I'm using images taken of a large checkerboard, and following the workflow outlined here: http://downloads.agisoft.ru/lens/doc/en/lens.pdf

My problem is that I import ~30 images of the checkerboard, select Tools -> Camera Calibration, and then select OK (image attached of this window)... and nothing happens. The manual says that a dialog box should appear, and the calibration results will appear in the report window.

The only problem I can think of, is that in the calibration images, the checkerboard does not take up the full screen (example image attached), like the manual suggests.

Thanks for any help!

(I'm running photoscan version 1.2.6 build 2834)

Hello lvargo13,

According to the sacreenshot, you are using PhotoScan, but you intention (according to your post) was to use Agisoft Lens, so to solve the problem you need to run Agisoft Lens.

Also the checkerboard should occupy the most of the image frame, if you intend to use the it for the calibration, whereas on your screenshot only a small part of the image is used.
