Real-time object motion detection system and related method
First Claim
1. A real-time object motion detection system comprising a first object and a second object in relative movement, wherein:
- the first object sequentially sends a plurality of signal pairs at continuous time points, every signal pair comprising a first signal and a corresponding second signal, and a first propagation speed of the first signal is faster than a second propagation speed of the second signal; and
the second object receives the plurality of first signals and second signals, wherein after receiving one first signal, the second object starts to count until receiving the corresponding second signal to obtain a time difference, and then utilizes the time difference to calculate a relative movement distance and speed.
