Detection system and detection method

A detection system, comprising:

• a first detector, configured to generate a first detection signal when a target is detected in a first detection range;
• a second detector, configured to generate a second detection signal when the target is detected in a second detection range;
• at least one actuator;
• a storage unit, for storing a program instruction and a plurality of historical movement paths;
• and
• a processing device, connected to the first detector, the second detector, the storage unit and the actuator, the processing device is configured to access the program instruction from the storage unit, to execute the following steps:
• establishing a detection movement path according to the first detection signal and the second detection signal;
• comparing the detection movement path with the historical movement paths, to select a best matching historical movement path that best matches the detection movement path from the historical movement paths;
• and
• transmitting a driving signal to the actuator located in the third detection range to drive the actuator when the target is predicted to move to a third detection range according to the best matching historical movement path.
