Parallax telemetry

Much like the 360 camera used by the Google Maps cars, this device would 360 degree spin a small vertical array of range finding lasers in a wedge shaped spread around ones helmet which would send real-time feedback to a program designed to use the parallax of the most immediate objects having certain tree-like characteristics and filter them out so as to see in an ever widening circle beyond them.

Standing still the device will only be able to map a small area around you, but movement will, much like looking past the trees in a moving car, let you catch glimpses of the landscape behind, this would allow you to see on a screen what is behind the forest or jungle you've been walking through, be it animal human or terrain.

If this already exists I haven't been able to find it but my gut says that it's coming soon to a military grade visor near you if it hasn't already.
