Rig for automatic scan (with textures) of an entire object, all you have to do is place the object and press scan.
The software and hardware communicate using the com port, See the list of commands/messages in the advanced settings in the David Laserscanner software.
Here's a video we made.. we made it more action than information, because we got bored with wathcing most of the "look what i built" videos out there Clicky hery: http://www.youtube.com/watch?v=mIcd4f8dz-Y
If you're interested there' a disgustingly messy flowchart (with the wrong commands ) of the flow of communication at:
The "control" part of the hardware will eventually be made on a single PCB, and we're thinking of selling it... (cheap of course
The PIC µC was programmed in embedded C, using Microchips MPLAB.
The frame of this Setup was inspired by the "aufbau" video from http://youtube.com/user/sehertest , We made some adjustments so that it can run in a lighted room.
The Hardware is based on a PIC24 µC, (PIC24HJ128GP502)
an FTDI chip serial for communication with PC, (MM232RQ)
an RC servo for turning the laser,
a step motor for turning the scanned object using an A3967 step motor controller.
The whole rig is powered by a standard PC PSU,
It took about 8 weeks to complete.
We aren't using a webcam because we didn't have proper x64 drivers for it
