Claims18
A method comprising:
- acquiring a plurality of training images through a capturing component;
- acquiring a plurality of training camera poses of the capturing component corresponding to the training images through a pose sensor disposed corresponding to the capturing component;
- and
- training a camera pose estimation model according to the training images and the training camera poses of the capturing component;
- wherein the operation of training the camera pose estimation model comprises:
- extracting training feature sets from the training images by using a feature extracting module;
- calculating estimating camera poses according to the training feature sets by using a pose regressor;
- and
- training the camera pose estimation model according to loss functions corresponding to differences between the estimating camera poses and the training camera poses, wherein the loss functions include a plurality of inputs, and wherein the inputs include the estimating camera poses, and the estimating camera poses are a function of the training feature sets.
