Miniature curved artificial compound eyes: The Artificial Insect Eye That Will Give Sight To Tiny Drones

Miniature curved artificial compound eyes: The Artificial Insect Eye That Will Give Sight To Tiny Drones | Military Drones | Scoop.it

In most animal species, vision is mediated by compound eyes, which offer lower resolution than vertebrate single-lens eyes, but significantly larger fields of view with negligible distortion and spherical aberration, as well as high temporal resolution in a tiny package. Compound eyes are ideally suited for fast panoramic motion perception. Engineering a miniature artificial compound eye is challenging because it requires accurate alignment of photoreceptive and optical components on a curved surface. Here, we describe a unique design method for biomimetic compound eyes featuring a panoramic, undistorted field of view in a very thin package. The design consists of three planar layers of separately produced arrays, namely, a microlens array, a neuromorphic photodetector array, and a flexible printed circuit board that are stacked, cut, and curved to produce a mechanically flexible imager. Following this method, we have prototyped and characterized an artificial compound eye bearing a hemispherical field of view with embedded and programmable low-power signal processing, high temporal resolution, and local adaptation to illumination. The prototyped artificial compound eye possesses several characteristics similar to the eye of the fruit fly Drosophila and other arthropod species. This design method opens up additional vistas for a broad range of applications in which wide field motion detection is at a premium, such as collision-free navigation of terrestrial and aerospace vehicles, and for the experimental testing of insect vision theories.

Port Alfred Family gives millions to supply drones to fight rhino poachers

Port Alfred Family gives millions to supply drones to fight rhino poachers | Military Drones | Scoop.it

A Port Alfred family has splashed out millions on hi-tech helicopter drones to try to save the African rhino from poachers.

 

What started out as a fun idea by businessman Anton Kieser to attach a digital camera to his remote-controlled helicopter has turned into a R3-million investment with brother Leon and father Kees.

 

The equipment, which includes imported drones and thermal imaging cameras, will be tested at local game reserves.

 

Although other anti-poaching initiatives in South Africa are also using unmanned aerial vehicle (UAV) drones to try and save the rhino from extinction, they are using less manoeuvrable planes, not helicopters.

 

"We bought all this hi-tech equipment to try and combat rhino poaching before they are all gone," Anton explained. ..

This is awesome!

Drones are going to be what save the rhino.

Many thanks to the Kieser family for their generosity.

Let's follow suit and help get more drones/UAVs in the air
