Abstract: The present disclosure provides a tracking system and method thereof. The tracking system comprises a trackable device with an appearance including a feature pattern and a tracking device. The tracking device comprises an optical sensor module configured to capture a first image which covers the trackable device. The tracking device further comprises a processor coupled to the optical sensor module. The processor is configured to retrieve a region of interest (ROI) of the first image based on the feature pattern, and locate a position of each of a plurality of feature blocks in the ROI, where each feature block contains a portion of the feature pattern. The processor further calculates a pose data of the trackable object according to the positions of the feature blocks.

Abstract: A tracking system is provided. The tracking system comprises a trackable device which comprises a first illuminating module and the first illuminating module emits an infrared (IR) light and a tracking device which comprises an optical sensing module and a processor. The optical module is configured to sense an IR spectrum to capture a first image and sense a visible spectrum to capture a second image, and the IR light is in the IR spectrum. The processor is coupled to the optical sensing module. The processor is configured to search in the first image a first region corresponding to the IR light, locate in the second image a second region associated with the first region in the first image, and calculate a spatial status of the trackable device according to the second region in the second image.
