One thing I haven't still solved: How can I set the Flash presentation that it has the best initial position to the observer?
What I mean: Before we do anything with the mouse we are looking on the backside of the Nokia. And it is angular and not upright.

Has anybody an idea?

Walter

Edit: Sven has shown me the way by using the parameters 'pitch' and 'yaw':

Now with pitch=-70&yaw=157 it's fine. Thanks!

I've scanned my bike so i can make an exhaust pipe tailor made to fit and suit the (correctly calculated) engine set-up EI: capacity, valve timing, con rod length, etc
I first scanned the whole area, then took off the existing exhaust, then scanned the bike again, as well as the exhaust.
Then i could assembly the exhaust onto the bike without exhaust, and use the full scan as a positional reference.
Now I can design a new one using the other as a reference for clearance (particularly behind the front wheel),
But in a 4-2-1 configuration with the correct dimensions, (within my 3D CAD system NX8)

Not my cleanest scan - but not bad for my first effort on this scale. . . .

To be honest, I got bored of cleaning up the scans and aligning them!

@ macdaddyjaz:

Good work, congrats!
Can you please inform us how you have scanned the Volkswagen Mk1 Golf Cabrio? Means was is sprayed before? What projector and camera was used? How were both devices arranged? One above the other or side by side? What kind of calibration corner was used?

Sure thing Walter, here is the tech list!

-Optoma EP1690 - 1280 x 768
-Canon 40D
-Macbook pro on bootcamp
-Home made adjustable rig (I will do some pics at some point) mounted on a telescope tripod
-Calibration panels 1200mm x 1000mm per panel (I cut 2 panels from an 8' x 4' sheet) 90deg corner. I think the calib scale was 550mm (or somewhere near)

EDIT - The car paintwork was not that shiny but it was black so it was necessary to give a light mist with white spray. It was scanned in the relative darkness of a barn with the windows partially blocked. Not pitch black but dim - enough to get a good contrast on the projection.

Shape fusion worked for the most part but it is really missing the manual alignment IMO.

As a first attempt I was most interested in getting distortionless scans and the surface quality was not important but the scans were of a surprising quality for the scale I was working on. I am certain that with more care and a few mods to my rig I can make significant improvements in the surface quality too.

Hi Mattia , thank you for the praise
my graphic card is a NVIDIA Quadro FX 1800 -> output to beamer is Displayport -> cable (Displayport to HDMI) -> Beamer
I hope I could help .

Thanks,

but here seems that something goes wrong: compared with the ACER K11 the DELL create more noise (linear and regular small waves - probably have some problems with the camera) and have more more distortions (really hard to align the scans).

So, if for you works good, I guess here the problem should be still to discover... heheh

The modified Logitech C600 with a resolution of 800 x 600 @15fps. My head was leant against the wooden padded headrest. Three single scans, not smoothed, were fused at a resolution of 550 and a sharpness of 5.

The scan time, only the horizontal stripes were used, was about 6 sec each.

Walter

PS. The scar under my chin is true, but much smaller.

I can not find the sharpness parameter?

At that time we started SL scanning with version 3.0:
viewtopic.php?p=18186#p18186

All the next versions haven't this parameter setting. Probably it is already integrated in the newer DAVID software.

COM Control

Postby Athena » Thu Feb 07, 2013 9:13 pm

Hello MagWeb,

You seemed to have worked on David SL Com control. I hope you can help me on this. We want to control a 3D SL application without using David GUI. We have a test program written in VB6 (I know it's archaic but it is simple and easy for me). So I installed com0com and created two com ports Com11 and Com12 and set David to use Com12. The idea is to make a scan (SL type not laser), and save the scan data to a obj.file. So here are the steps:

1. Open com ports Com11 and Com12
2. Click on the scan button on the program to send "S" command (Scan) to Com11 to initiate the scan
3. Detect that scan is completed by checking Com12 input buffer to see if "StopScanning" message is sent by David
4. If it is true, then send "Z" command to Com11 to save the obj file.

Here it might be necessary to check if the scan is completed in 0.5 second intervals or so in a time routine until the scanning is finished.

Is this the procedure? Any pointers will be greatly appreciated.

Sincerely,


Private Sub Form_Load()

MSComm11.PortOpen = True
MSComm12.PortOpen = True

End Sub

Private Sub cmdCommand_Click()

MSComm11.Output = "S" & vbCrLf

End Sub

Private Sub MSComm12_OnComm()

Select Case MSComm1.CommEvent

Case comEvReceive ' Received RThreshold # of ' chars.

If MSComm12.Input = "StopScanning" Then
MSComm11.Output = "Z" & vbCrLf
End If

End Select

End Sub
Athena
