1. A system for tracking a creature body, the system comprising:
an image capturing device, configured to capture an image of a target creature;
a radio frequency transceiver device, configured to transmit a radio signal to the target creature and receive a plurality of reflected signals from the target creature; and
a computing device, electrically connected to the radio frequency transceiver device and the image capturing device and comprising an image tracking module, a creature feature value database, and a comparison module, wherein the image tracking module is configured to track the target creature according to the image captured by the image capturing device, the creature feature value database comprises at least one registered identity and a plurality of creature feature values, the registered identity corresponds to at least one creature feature value, and the comparison module is configured to compare the reflected signals with the creature feature values in the creature feature value database, to find out a registered identity of the target creature, so that the image tracking module keeps tracking the target creature,
wherein the target creature comprises a plurality of feature points, the reflected signals comprise the plurality of creature feature values corresponding to the feature points, the creature feature values of the reflected signals comprise a feature point array formed by the reflected signals and the creature body formed by the feature points,
wherein the comparison module is configured to: compare the creature feature values of the reflected signals with the creature feature values of the creature feature value database in terms of the feature point array, and when a distance ratio of a plurality of sets of feature points corresponding to the creature feature values of the reflected signals from the target creature approximates a distance ratio of a plurality of sets of feature points corresponding to the creature feature values of the registered identity, determine that the registered identity of the target creature is found.
