ToF (time-of-flight) cameras seem susceptible to bright outdoor conditions.

Are there any sensors made for bright outdoor conditions and could be embeddable in a robot that could detect and/or track small objects (5cm - 25cm) with a range of 10m - 100m?

Would radar work?

  • $\begingroup$ @holmeski hmmm really? what if the speed at that distance wasn't very high? this is to track a golf ball. any suggestions on how to do this (beyond computer vision)? $\endgroup$ – Crashalot Oct 18 '16 at 18:39
  • $\begingroup$ Can you modify tracked objects, i.e put some transmitter in it? What is reading frequency that you would need? Do you need only azimuth, or distance also? $\endgroup$ – mactro Oct 19 '16 at 9:24

Tracking small objects is always tricky.

You can use Ultrasonic sound sensors. Calibrate it to the distance you want to detect. They have low range though.

If you can work on a more complex model then computer vision could also help (Highly unreliable- It needs to have a very strong filter algorithm)

  • $\begingroup$ Thanks for the answer! What about radar? $\endgroup$ – Crashalot Oct 18 '16 at 18:27
