Hi. I am tracking an object which is being moved via a motion control system. I would like to test for the latency between the objects movement and the tracking of the Pixy.
In other words, I need to find the time between the motion of the object and the sensing of motion by the Pixy.
Have you got any information of the Pixy’s latency?
Any help is appreciated.
Justin
Hi Justin,
Pixy runs at 50fps, so the theoretical maximum latency between detection is .02 seconds (1/50). This could increase, however. If you are interfacing to Pixy via an Arduino (for example), and in the previous frame Pixy detects 1000 objects, then it could take more time to send all of that data to your Arduino. Then you won’t receive the current frame’s object data until after all those objects are done transmitting. Basically what I’m saying is it can vary depending on your configuration and application.
If you aren’t detecting too many objects, then it would be just over .02 seconds for detecting and transfer of data.
