Abstract
An example system for tracking motion of an eye during an eye treatment includes an image capture device configured to capture a plurality of images of an eye. The system includes controller(s) including processor(s) that receive the plurality of images from the image capture device. The processor(s) implement a plurality of trackers. Each tracker is configured to detect a respective feature in the plurality of images and provide, based on the respective feature, a respective set of data relating to motion of the eye. The respective features detected by the plurality of trackers are orthogonal relative to each other and the respective sets of data provided by the plurality of trackers are independent of each other. The processor(s) coalesce the sets of data from the plurality of trackers and determine an indicator of the motion of the eye based on the coalesced sets of data.
