Claim 17:
18. A pose tracking device, an apparatus comprising:
an image capturing unit, configured to acquire continuous multiple-frame images of a scanned object;
an initial pose determination unit, configured to determine an initial pose of the image capturing unit;
a first pose acquisition unit, configured to by taking the initial pose as an initial value, acquire, 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;
a second pose acquisition unit, configured to by taking the first calculated pose as an initial value, acquire, 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
a pose update unit, configured to update the initial pose of the image capturing unit according to the second calculated pose, to achieve pose tracking of the image capturing unit.
