Re: Concept Discussion: Vision Closed Loop or Encoder/Gyro PID based Closed Loop?
Getting a camera to run any faster than 30fps takes special HW and pretty careful code. If 33ms is an OK loop rate for your mechanism, it is a valid sensor, otherwise you might want to augment with something faster -- and/or with less lag. In many situations, an ultrasonic, gyro, encoder, or pot makes a great compliment to the camera's higher-level control feedback.
It is great that you are asking for advice, but there are teams who will make both solutions work. My advice it to figure out how you can do a quick prototype or test.
