Claim 0:
1. A pose tracking method, the method comprising the following steps:
acquiring continuous multiple-frame images of a scanned object and an initial pose of an image capturing unit;
by taking the initial pose as an initial value, acquiring, on the basis of a previous frame image and a current frame image in the continuous multiple-frame images, a first calculated pose of the current frame image by using a first algorithm;
by taking the first calculated pose as an initial value, acquiring, on the basis of the current frame image and a current frame image reconstruction model, a second calculated pose of the current frame image by using a second algorithm; and
updating the initial pose of the image capturing unit according to the second calculated pose, and repeating acquiring continuous multiple frames and the initial pose, acquiring the first calculated pose, acquiring the second calculated pose, and updating the initial pose to achieve pose tracking of the image capturing unit.
