Demultiplexing illumination via low cost sensing and nanosecond coding
2014
2014 IEEE International Conference on Computational Photography (ICCP)
While previous work on illumination multiplexing has exploited coding at millisecond intervals, we repurpose sensors that are ordinarily used in time of flight imaging to demultiplex via nanosecond coding ...
Time of flight cameras are a low cost, consumer-oriented technology capable of acquiring range maps at 30 frames per second. ...
In contrast to previous approaches this technique exploits low cost time of flight sensors which allow nanosecond coding within the millisecond exposure. ...
