Abstract
A pose tracking method, a pose tracking device and an electronic device. The method comprises: acquiring continuous multiple images of a scanned object and an initial pose of an image capturing unit (S10); 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 (S12); 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 (S14); and updating the initial pose of the image capturing unit according to the second calculated pose, and repeating the described steps to achieve pose tracking of the image capturing unit (S16).
