I’m hoping to make a cosplay costume with servo operated eyes that look where the user is looking. I was hoping to achieve this sing an Esp8266 and ov7670 sensor. Is it possible to use the ov7670 for pupil tracking? If so, what code would I need to use to achieve that? I’d need to find the rough centre of the pupil then use that coordinate data to work out a direction for the X and Y servos for the eyes.
