Drones may take advantage in more than one way of the virtual reality buzz. Valve announced its Lighthouse positional tracking solution along with the HTC Vive, and more details are emerging about the inner working of the system. You can see above the tracking station. The two inner cylinders are rotating and project a horizontal and vertical laser line across the room. The LEDs visible on the PCB are probably for the synchronization signal.
With IR detectors on an object, is is possible to determine the position of the object using precise timing and trigonometry. Valve claims sub millimeter accuracy. The tracking station is dumb, meaning that it only projects the laser lines at a precise interval. You could add a few IR detectors on a drone and with the right interrupt based algorithm, even a 25$ Multiwii board running on the Atmega32u4 could position accurately a drone within a given space.
For drones, it means:
I think it is exciting news for research labs and enthusiasts. The system could provide the same level of accuracy as the $25k+ camera tracking systems. It will speed up development until full ultra precise embedded SLAM is available. I am looking forward to see the first reverse engineering post about the device protocol! Micro drones will navigate precisely inside a house.
