Greetings to all forum members.
At the beginning sorry for my English.
Well I must say that David is my first contact with 3D scanning (earlier read about it). I would like to make SL scanning.
My equipment (borrowed from friends) is
camera: IDS uEye UI-1550LE-C-HQ with 16mm 1:1,4 lenses.
Projector:
a) Casio XJ-A241
b) Optoma PK301
I was trying to make positive and negative corners with better or worse accuracy.
I had best effects with negative corner. But after making camera calibration my both projectors failed with their calibration. When I was trying to put projector closer or further without moving my camera everything went bad. And I couldn't be able to find a perfect position, or even get back to earlier "working" position. Also I am using 3.8.1 version. New 3.9 doesn't support my camera.
Now I'm trying positive A4 corner with 161mm scale but I can't find a good distance to pass camera calibration.
I tried several measurements on one position (camera,projector and corner without moving), and RMS value was jumping from 5.2 to even 220... and sometimes it just passed with RMS below 5.
Right now I can't send pictures of my set up. I don't have any tripods or anything like that. Corner, camera and projector ale on the floor.
I even tried setting camera and projector according to David wiki. But also unsuccessful.
I hope Someone will suggest anything.
With best wishes
Azun
ps. I saw that screenshot was made with red line little cut on blue line. Other trials were made with better precaution.
