APPARATUS AND METHOD FOR ESTIMATING UNCERTAINTY OF IMAGE COORDINATE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17708447 titled 'APPARATUS AND METHOD FOR ESTIMATING UNCERTAINTY OF IMAGE COORDINATE
Simplified Explanation
The patent application describes an apparatus for estimating uncertainty in tracking coordinates acquired from image and motion data. The apparatus includes a processor that receives a reference coordinate from image data and acquires a second tracking coordinate based on motion data and depth values. It then calculates a target coordinate distribution in the image data and estimates the target coordinate and its uncertainty. The first tracking coordinate is updated based on the estimated target coordinate.
- The apparatus estimates uncertainty in tracking coordinates acquired from image and motion data.
- It uses a processor to receive a reference coordinate from image data and acquire a second tracking coordinate based on motion data and depth values.
- The apparatus calculates a target coordinate distribution in the image data.
- It estimates the target coordinate and its uncertainty based on the calculated target coordinate distribution.
- The first tracking coordinate is updated based on the estimated target coordinate.
