2.1.7 Omnidirectional Binocular Vision 
Sensing System 
The  EVO 
Ⅱ ’s  front,  rear,  left,  right,  top,  and  bottom  binocular  vision  sensing 
systems use image data to calculate the distance between the aircraft and potential 
obstacles. The system will halt the aircraft’s forward progress when an obstacle is 
detected. 
The front, rear, and bottom binocular vision systems also feature the Starpoint™ 
Positioning System. This system uses ultrasonic sensors to calculate the current 
height of the aircraft, and uses the binocular cameras to obtain location information 
via image analysis.
