1. An image positioning device, comprising:
a calculation circuit, wherein the calculation circuit obtains a plurality of images from an image capturing device and classifies the images into a plurality of main groups based on a first algorithm, wherein each main group corresponds to a different area and the calculation circuit classifies the images of each main group into a plurality of sub-groups based on a feature of each image of each main group and a clustering algorithm;
a positioning circuit, coupled to the calculation circuit, wherein the positioning circuit positions each sub-group in the area corresponding to each main group based on a relative position relationship between each sub-group of each main group; and
a feature capturing circuit, coupled to the calculation circuit and sorting the images in each main group based on a time sequence of each image, obtaining a first relative moving distance between each image and its previous image in each main group based on a second algorithm, and obtaining a second relative moving distance between each image and the first image in each main group based on the first relative moving distance corresponding to each image in each main group, wherein the second relative moving distance of each image is taken as the feature of each image.
