Method and system for tracking object for augmented reality

An object tracking system for augmented reality comprising:

• at least one memory storing a tracking application;
• and
• at least one processor performing object tracking for augmented reality by reading the tracking application stored in the memory,
• wherein commands of the tracking application include commands for performing:
• obtaining a 3D definition model trained based on images capturing a target object from a first viewpoint,
• performing object tracking of the target object based on the obtained 3D definition model,
• obtaining a plurality of frame images from a plurality of viewpoints for the target object based on the object tracking,
• learning the target object from the plurality of viewpoints based on the plurality of frame images obtained,
• updating the 3D definition model based on the learning, and
• performing AR object tracking for the target object based on the updated 3D definition model.
