Original Abstract Submitted
the augmented reality system includes a needle, a camera, an ultrasound generator, a memory, and a processor. the needle includes a location code, a first marking area, and a second marking area. the processor is used to perform following steps: capturing the location code, the first marking area, and the second marking area of the needle to perform positioning or a marking pose estimation by the camera; obtaining a feature points number according to the first marking area and the second marking area; obtaining a range prediction interval of the ultrasound field of view according to the feature points number of the needle; increasing or decreasing the range prediction interval according to the feature points number and a feature points number threshold; and when it is determined that the feature points number is greater than the feature points number threshold, the range prediction interval is reduced.
