Are any commercially available compound vision sensors available? Not a simple 8 sensor system using photo-diodes but a genuine sensor that can provide a >32x32 compound matrix. Would some form of reduction in the granularity of a megapixel camera be a better option? The real purpose is to reduce processing time to a minimum, while extracting the maximum basic information.

  • $\begingroup$ Is there a problem with simply using a regular camera and resizing the image down to 32×32 pixels? $\endgroup$ – Ian Mar 12 '15 at 16:11
  • $\begingroup$ @Ian; I was looking for a compound vision sensor, but did ask if a reduction in a standard camera resolution would be better $\endgroup$ – Neomada Mar 12 '15 at 18:16
  • $\begingroup$ I'm asking if there's a specific reason why you wouldn't want to use the camera, since you seem to be having trouble finding the exact vision sensor you want. $\endgroup$ – Ian Mar 13 '15 at 21:13
  • $\begingroup$ @Ian; I would have liked to try a compound camera to enable some bio-emulation/understanding, but I will be using a camera (possibly limiting the number of pixels processed or merging blocks of pixels).Thanks $\endgroup$ – Neomada Mar 14 '15 at 13:36

The following people have used a compound eye for the development of their insect inspired rotor craft to demonstrate panoramic optical flow methods without the use of accelerometers.

Flying over uneven moving terrain based on optic-flow cues without any need for reference frames or accelerometers

The sensors are described here; Curvace

Paper here; Miniature curved artificial compound eyes
