Progress with the Piscan 3D scanner. The scans are now automated and the raspberry pi is connected by USB via the UART connection. The scans can be saved to a number of point cloud formats.

I have also started building the electronics as a single add on For the pi.

The to do list is still long but we're getting there.

Great to see quality open source contributions. Good work +Ultimaker!
 
March, 28th 2014 - this day will be remembered: +Ultimaker is releasing the plans for their beautiful #Ultimaker2  under the CC-BY-NC-SA license.

Epic win for #OSHW  . Thanks +Erik de Bruijn , +Martijn Elserman,+Siert Wijnia & team for the vision you bring to the industry. 
Ultimaker 2 open source design files and documentation, including the Bill of Materials, the 3D files and documentation for each part.

Update on the Raspberry Pi Scanner.
 
Really starting to make progress with the scanner now.

I've rewritten the Raspberry Pi code in C++ and started to build the serial communication protocol between the interface and the scanner.

The interface is OpenGL and the processing is now threaded and updates the ui in realtime.

More soon.

Using this method: http://www.sjbaker.org/wiki/index.php?title=A_Simple_3D_Scanner
The RPi controls the laser, camera and turntable and passes data back to the ui where its processed and presented as a pointcloud.

Made a little more progress with Piscan: Automagic error removal (Well almost, its the red bits)

I haven't contacted anyone about the project yet. I want something solid that works reliably before I start trying to get other people involved.

Very nice, looking forward to some cool scans.

A bit of an odd one here. I'm sending an image file from a raspberry pi over serial connected via USB to another machine. I have a Qt thread that receives the data and writes it to an image file. Everything is working but its very slow. I'm currently sending a 320x240 image and it takes 20 seconds.

The pi side uses Termios to make the connection and logs any errors and its currently logging 6 million errors of 'resource busy' for 230400 byte transfer.

Any advice, tips or help welcomed.

I don't do checksums now. The software works as a 3D laserline scanner. 

The laser intersects a point on an object and this point is calculated using triangulation from the brightest pixel on the row of the image. This yields a xyz coordinate and a pixel colour. This information is transferred over serial in a predetermined format such as <X:Y:Z:C>.  The receiving machine can check if the format has been maintained and the data is complete. if not it can discard that point. 

It seems to get 100% success with transfer of the data. worst case is a few points are discarded from up to 1 million points.

There are so many applications for this. Cars, bikes, 3d printers, smart watch, walking GPS, gadgets and gizmos galore.
