Micro-electro-mechanical system (MEMS) pico-projectos can be used to project calibrated stripes of light whose deformation reveals the 3D dimensions of the objects being imaged. Look for automatic generation of detailed 3D models, just by aiming your smartphone's pico-projector at it, within three years. RColinJohnson @NextGenLog
Structured light illumination (left) permits 3D models, here of a patient's chest, to be automatically generated (right).
Here is what Smarter Technology says about SLI: 3D models, which usually require tedious manual measurements, can now be automatically created from real-life scenes using structured light illumination (SLI) technology with micro-electro-mechanical system (MEMS) pico-projectors. The algorithms for applications from video gaming to medical diagnosis are being pioneered at the Center for Visualization and Virtual Environments at the University of Kentucky and commercialized by Seikowave (Lexington, Kentucky)...
