Physical Bases of a ToF Camera–Based Optical Tracking System for Surgical Instruments

Аннотация

The physical principles of the operation of time-of-flight (ToF) cameras used for forming three-dimensional images are considered. Estimates of ToF camera characteristics are obtained using the example of a Kinect device. Algorithms for processing of three-dimensional images in a system of intraoperative navigation are described. Estimates of the accuracy of identifying the position of a surgical instrument are obtained.
