Host, single-camera-based tracking system, and single-camera-based tracking method

A single-camera-based tracking system, comprising:

• a tracking device, comprising a camera, wherein the camera is configured to obtain image data;
• a storage circuit, configured to store a program code;
• and
• a processor, coupled to the storage circuit and configured to access the program code to execute:
• obtaining the image data through the camera of the tracking device, wherein the tracking device is configured to be disposed on a home location;
• determining that whether the tracking device is at the home location or not based on the image data;
• in response to the tracking device being not at the home location, performing a device tracking of the tracking device based on the image data;
• determining a device coordinate of the tracking device based on the device tracking;
• determining that whether the tracking device is disposed back to the home location or not based on the image data;
• and
• in response to the tracking device being disposed back to the home location, determining that the device coordinate of the tracking device being same as a home coordinate of the home location.

A single-camera-based tracking method, comprising:

• obtaining, by a processor, image data through a camera of a tracking device, wherein the tracking device is configured to be disposed on a home location;
• determining, by the processor, that whether the tracking device is at the home location or not based on the image data;
• in response to the tracking device being not at the home location, performing, by the processor, a device tracking of the tracking device based on the image data;
• determining, by the processor, a device coordinate of the tracking device based on the device tracking;
• determining, by the processor, that whether the tracking device is disposed back to the home location or not based on the image data;
• and
• in response to the tracking device being disposed back to the home location, determining, by the processor, that the device coordinate of the tracking device being same as a home coordinate of the home location.
