Click the “Calibrate” button to finish calibration.

====Step 7 First scan==== | |||
Now everything is ready. We could start our first scan. Do remember to check the “Record new motion “option. One important thing is you need to re-adjust the camera setting, unlike the calibration picture, now you need to achieve a picture as black as possible while only the laser line could be easily recognized ,and you can also adjust the laser focus to make it as thin as possible. Like the picture showed below. | |||

====Step 8==== | |||
Once you finish the first scan. We can do the repetition scan. Just make sure the relative position of the laser and the camera is fixed and we can remove the calibration board to scan anything we want. We now finish the mobile laser scanner. | |||
Here is some demo scan result from the official David site (from the commercial version) . | |||
