Welcome everybody,
This is the place where I'm keeping you informed about the 3D-scanner project. After a week of snowboarding I started this Monday with fresh energy. Luckily the green laser I ordered arrived. It is a 5 mw, 532 nm laser pointer. With this capacity you can spread the beam so it becomes a line on the surface you put it on, but the beam it self isn't visible yet, this will happen if you take a stronger laser. The problem then is that you are getting problems with filtering where the laser touches the object and not where it is just visible in the air.
In two weeks I came up with the following:
A 3D-scanner with as many open source software as possible and as cheap as possible. The goal is to make the scanner available for everybody, the costs need to be under 500 euro for the materials.
So far I bought myself the green laser mentioned above. I found it at www.warnlaser.com and within a week the package arrived.
For the software I downloaded MeshLab to generate a 3D model from a point cloud. Unfortunately that’s not enough, soon I will order the software package from TriAngles, compared to other programs its relative cheap, 150 dollar.
New HD camera(HD camera 3)
When I went to Urk to return the camera the people at CameraNu where really nice. They checked the camera for any damage and then returned it altough I officialy was to late. Unfortnuatly they couldn't give me advice on what camcorder I should buy to use as a webcam. So I went back to Utrecht without a camcorder. After some research on internet it appeared that Sanyo camcorders had a webcam function. I orderd the Sanyo VPC-HD2000, a full HD 1080p 60fps camera! Now pray it will have good specs as a webcam, and I get it in time.
HD camera 2
After we all tried to use tje camcorder as a webcam, and all failed we decided to go look for a new camcorder. Tomorrow I will go to the shop to see if I can return it and look for a diffrent camera. More about all this tomorrow.
HD camera
The HD JVC video camera we bought is still not working on the PC as we want. Live streaming of the image isn't possible so far. This afternoon Siert and I will take a look at it to see if we can do something about it. Also the reconstruction of the new lab rooms is taking a lot of my time. Last friday I visited Petit en Fritzen, the church bell maker. With a group of 40 people we saw the casting of one of the bigger bells. This was really interesting! Hope to be able to make some more scans soon with the HD camera.
Adjustment internship assignment
Last Friday I had a meeting with Siert, the Lab Manager. At one point we came to the conclusion that it isn't useful to build my platform for my own 3D-scanner, its not a challenge to build and what's the point of having two turntables? They main goal was to make a copy of a Playmobil doll, that I already did, although not with my own scanner.
The next task is to build a box for the IntriCad scanner so other people can make scans quickly. I also gone write the tutorial on how to use the machine for an easy and quick scan.
Visit of IntriCad to Protospace
Thursday Mr. Rao from Intricad came to Utrecht for a visit to ProtoSpace. He explained shortly how to place all the components of the scanner and made a scan with his own camera. The results where a lot better then what I made with the webcam. Probably the effect of more experience and better material. From then on I decided there need to come a camcorder, and quick. Lucky for me I could borrow one from a college, it was even equipped with Firewire!
First 3D scan with help of the IntriCad scanner
Not yet what I've hoped but at least I got something.
The Intricad 3D-scanner
Last Thursday I picked up the Intricad TriAngles 3D-scanner. I'm the first one with the second version! There are some small problems with holes that doesn't line up perfectly but so far its looking good.
I hope to make my first scan today, pictures will follow soon.
Zegel voor Vleutense klok
Bart Bakker kwam een tijdje geleden met het voorstel om een zegel te scannen. Er wordt namelijk een nieuwe klok gemaakt, op deze klok wouden ze twee zegels. Een van de zegels zat vast aan het oudste document van Utrecht, uit 1280!
Het idee was om met een scanner naar het archief te gaan om daar te scannen. Uiteindelijk zijn er gipsen afgietsels uit 1890 naar het lab gehaald en hebben we die hier gescand.
First scan and copy in association with the HU
Two weeks ago I picked up a laser scanner from the HU(Hogeschool van Utrecht), it is a Roland Picza. Unfortunately they lost the power cable, data cable and all software. I’ve looked for a couple of days to the missing pieces. Then I got a nice tip, try the Roland CNC milling machine for the software and cables, and all worked great with the scanner. After a couple of scans I decided to 3D-print the best one, a Playmobiel doll. The hole process took less then a day.
Working line laser
Wensday the 11th of March I finaly got my line laser working!
First of all I will shortly explain what a line laser is, a normal laser is a dot, for a 3D-scanner and many other projects its more usefull to have a line, that is a line laser.
When I started my internship I tried to make a line with a cylindric clear glass or acrylic tube. With this method you get a line because of the breaking of light when it goes from air to glass and back.but the intensity varies with a bright dot in the middle and its losing intensity to the end really quick.
Motors and lasers
Friday 27th of Februari I followed a workshop from Idea to Market, this was really usefull, as a product designer you often have this problem and at school they haven't told me much about patents and how to deal with them.
Monday morning I had a meeting with B.J. Rao from Intricad, because they have a 3D scanner with the idea to keep the costs as low as possible. Thats why I thoughed it would be really interesting to haver a chat with them about the problems and how to solve.
