/Measuring distance using a webcam and a laser/

This technolgy works off basic trigonometry (well explained in a short
video). The working prototype costs less than 20 EUR. I hope it will
appear in an industrial form before long.

I envision cycling with a small 2D laser mapping device along a street
and the map is automatically generated by the device's software and
later uploaded to a server. If it knows its position on a street and
exact distances and angles to numerous dots on obstacles around, the
program may recognize shapes and draw the map.

It seems it could be cheaper to send photons (laser beam) up in the air
than protons (a drone). A laser beam range could be several hundred or
even thousand meters.
