Autonomous electronic apparatus and navigation method thereof

An autonomous electronic apparatus, comprising:

• a communication unit, receiving a calling signal through a wireless sensor network, wherein the calling signal is from a target;
• a navigation module, coupled to the communication unit and analyzing a position relationship between the target and the autonomous electronic apparatus to generate a first speed;
• an image tracking module, comprising:
• an image capturing unit, capturing an image set;
• and
• an analyzing unit, coupled to the image capturing unit and analyzing an image relationship between the image set and the target to generate a second speed;
• and
• a processing unit, coupled to the navigation module and the analyzing unit, calculating a weighting value related to the position relationship, calculating a moving speed according to the weighting value, the first speed and the second speed and controlling a moving status of the autonomous electronic apparatus to move toward the target via the moving speed.
