How to calibrate with a picture

Postby AIMED » Wed Nov 06, 2013 6:33 pm

Hi Guys
Once I read that we can calibrate the camera with image. But I dont know how. I would like to know how to do that?

Hello,
take a shot of the calibration markers and of the patterns.
Then, load them into Setup Type field > Camera > Image grabber.

Best regards,
Mattia

Hello,
sorry for the late reply.
To calibrate the scanner, you don't need the video (calibrate the camera). An image is enough.
Then David don't convert the image in to 3D points. In order to scan, David need videos: video of a laser line above the object and panels or video of the SL patterns projected on the subject and panels.
