homemade 3d scanner - the working principle setup:the basic setup consists of a line laser module, a pc cam and a stepper motor controller card connected to one stepper motor. the laser is mounted on top of the stepper motor axis. the camera is placed at a well defined position with respect to the laser (the maximum detail resolution of the digitized part is determined by the resolution of the stepper motor, its gearing and the resolution of the cam). the object is placed in front of the cam in such a way that as much as possible of it is visible to the cam. at the same time the laser should be able to sweep the entire part, generating a well visible line on the object. scanning procedure:1) turn on laser 2) get image from cam3) analyze image, find laser line 4) calc 3d position of line points5) move laser 6) loop 2 to 5 until done7) turn off laser 8) mesh points calculating the position of the points in space is actually pretty simple vector algebra: λ×c = d + η×l1 + μ×l2
3D Scanning System The last couple of years have seen an explosion in home fabrication, with fantastic projects like RepRap and Fab@Home really helping to bring the open source community together. Unfortunately, 3D scanning — in many ways the flipside of the home fabrication coin — seems to have fallen by the wayside. I decided to start the 3D scanning ball rolling by creating the SplineScan computer-controlled turntable. The turntable uses a gearbox for precise positioning, and has fixings for lasers, lights, and cameras. The obvious use of the turntable is for 3D scanning, although it can be adapted very easily to rotate objects for accurate photography or interactive display. I’m currently using the turntable to archive and measure ancient artifacts as part of my Ph.D. studies ( and I have to say that I’m very happy with the results so far. The parts list might look a bit daunting, but the project is not difficult to make. Chassis This is the backbone of the scanner.

3M Pocket Projector (3M MPro160): Electronics Generating 3D Models of Your Face in Real-time with RGB Toshiba's researchers can generate real time models of your face using just one camera and some red, green, and blue lights. Want a 3D movie of an object? Forget scanners, forget stereoscopic cameras. All you need to capture real-time 3D movement is one camera and some colored lights. Researchers at Toshiba’s Cambridge Research Lab (CRL) have developed a new process that uses red, green, and blue light to capture a 3D image of your face. Better still, the system can record all the movements and facial expressions as they happen. Generating a 3D computer model of a solid object is fairly simple these days. As RGB lights overlap they illuminate the contours of the human face in different colors corresponding to the inclination of its surface. Current systems require you to be in a dark room, but ideally the system would be used under normal conditions. [image credit: Natasha Lomas/Silicon.com] [sources: Toshiba CRL, Silicon.com]
What is NI X Series? X Series devices are the most advanced multifunction data acquisition (DAQ) devices ever designed by National Instruments. They feature enhancements to address the needs of the most demanding test, measurement, and control applications. Available for USB, PCI Express, and PXI Express, each X Series device includes analog I/O, digital I/O, and four 32-bit counter/timers.
