Method for determining location and movement of a moving object
First Claim
1. A motion tracking method for determining the location and orientation of at least one object moving in space, comprising the steps of:
- generating structured light;
projecting structured light onto a target;
receiving return light from the target through an optical receiver;
converting the return light into coordinate data; and
translating the coordinate data into motion information.

Abstract
The present invention discloses a method for determining location and movement of a moving object. One embodiment of the method tracks the movement of a target during medical imaging scanning and transmits the position shift to the medical imaging scanning device in real time. The method includes the steps of projecting structured light on the target, receiving the reflection of structured light, converting the received structured light into spatial positions, and transmitting the positional shift to the medical imaging scanning device. The method further includes the step of adjusting the medical imaging scanning device in response to the positional change to increase accuracy.
