Hi,

This is my first 6 sided fusion. I know it's not very impressive but I wanted to share it because of all the help I have received on this forum that got me this far. I am getting a much better cam with an optical lense and I am going to use a "helper" the next time I do the car again.

thanks

erniej

good

Ciao. Well done: if we consider the fact that is a metal object, with reflection artifacts and many different colours, we can write that is a cute good result. Can I ask you a question? -> Can you publish, near your scan-mesh, the photo of object? Just a little image in low resolution, only to have an idea about what are the real proprietis of the objects. Thanks and bye, Mattia

Thank you Bongobat.

Here is an other fusion of the Austin Martin. It is somewhat better but I am still am having problems with "bad linking" (flashings).

Thanks again for the compliment.

Mattia's request

Postby erniej » Sat Feb 09, 2008 1:58 am

Hi Mattia,

Here is the object I used. it was first painted with flat (matt) white washable poster paint. I re-painted with flat (matt) green paint. I am going to try it again tomorrow morning.

Just a note, this picture was taken by a camera and is not the angle from my webcam.

Thank you for your interest.

hi

Postby hal » Sat Feb 09, 2008 2:58 pm

Hi, erniej. First of all, one note: in the middle of calib-coner I see a little gap, a space between the two sheets with marker. I see true? Because this can generate an error during scanning. I think you using the "standard" Calibpoints.dat file. With it, you must be sure that the two origin (x=0; y=0 ; z=0), of markers in different sheets, must be coincident. But, perhaps, I do a mistake (your camera's shot is in low resolution, I can't see clear).
Other thing: if your object is small, you can use a set of makers more suitable for its size. In this case your calib angle (distance between markers) is larger then need. Bye and good scans, Mattia

camera

Postby erniej » Sat Feb 09, 2008 5:30 pm

Hi,

The picture was taken by a camera and is not the angle from my webcam. The picture below is what my webcam sees when i calibrate it.
The blue line on the left does not show up. I got that when I did a screen capture of the calibration window.

flat black paint

Postby erniej » Sat Feb 09, 2008 5:36 pm

Hi,

Below is a fusion I did after I painted the object with a washable flat (matt) black paint. I did not touch up the scans with any type of smoothing and registered them right from the scans.

On the back side you can almost read the text. The slot is for coins.

The surface of the object is cast metal and has a rough surface. the scans picked that up nicly.

I found that the flat black paint removed most of my "bad linking" and the the laser line showed up thinner than before i used the paint. It's washable and comes right off.
