PX4Flow

Description

PX4Flow is an optical flow smart camera. It has a native resolution of 752×480 pixels and calculates optical flow on a 4x binned and cropped area at 250 Hz (bright, outdoors), giving it a very high light sensitivity. Unlike many mouse sensors, it also works indoors and in low outdoor light conditions without the need for an illumination LED at 120 Hz (dark, indoors). It can be freely reprogrammed to do any other basic, efficient low-level computer vision task.
