This explains why the images look like crap.<br /><br />This is another ivory project from Google/Motorola with little long-term, mass-production potential. Poor overall architecture for an outdoor mapping device. My prediction is this will be used by academic and government types for silly projects but long-term it is a dead donkey given there are superior architectures on the horizon.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-20228656783688414882014-02-24T13:53:16.769+02:002014-02-24T13:53:16.769+02:00If this is ToF or structured light, where is the l...If this is ToF or structured light, where is the light source? Behind the plastic cover? Possible, but it is not mentioned with any words. However it would explain the high power consumption. My first guess is a plenoptic/lightfield camera approach, like e.g. Pelican. In the video at 0:27 the user changes the focus of an ordinary image by a finger tip.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-3421715748043595832014-02-23T13:27:04.214+02:002014-02-23T13:27:04.214+02:00This kind of systems exist already in industrial a...This kind of systems exist already in industrial applications.

It's probably a short range ToF camera.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-30820093478148230022014-02-22T00:39:45.452+02:002014-02-22T00:39:45.452+02:00Their website says it measures 250k 3D points per ...Their website says it measures 250k 3D points per second.
