Method and system for augmented-reality object tracking

A system for AR object tracking comprising:

• at least one memory storing a tracking application;
• and
• at least one processor performing AR object tracking by reading the tracking application stored in the memory,
• wherein commands of the tracking application include commands for performing:
• obtaining first image data,
• providing a primitive model with a preconfigured 2D or 3D shape,
• determining at least one of the provided primitive model as a primitive application model,
• displaying the primitive application model on the first image data,
• performing alignment between the primitive application model and a target object within the first image data,
• setting attribute values specifying the shape of the primitive application model,
• obtaining 3D depth data including each descriptor of the target object and a distance value corresponding to the descriptor based on the set attribute values, and
• performing AR object tracking based on the 3D depth data.
