Image positioning device and method

An image positioning method, applied to an image positioning device, comprising:

• obtaining, by a calculation circuit of the image positioning device, a plurality of images from an image capturing device;
• classifying, by the calculation circuit, the images into a plurality of main groups based on a first algorithm, wherein each main group corresponds to a different area;
• classifying, by the calculation circuit, 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;
• and
• positioning, by a positioning circuit of the image positioning device, 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,
• wherein the method further comprises:
• sorting, by a feature capturing circuit of the image positioning device, the images in each main group based on a time sequence of each image;
• obtaining, by the feature capturing circuit, a first relative moving distance between each image and its previous image in each main group based on a second algorithm;
• and
• obtaining, by the feature capturing circuit, 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.
