Method for building an image data base, image recognition method, image recognition system and uses thereof
NOVELTY – The method involves acquiring (101) reference images from different positions in different lighting conditions according to time of day and atmospheric pressure. The images are preprocessed (102). The characteristic points of an image is extracted (103). The characteristic points of each site is stored (104) in a database. The characteristic points of each site is photographed. The common characteristic points in the images are searched. The list with the pairs of points are matched. USE – Method for constructing an image database in an image recognition system (Claimed). ADVANTAGE – The method includes photographing characteristic points of each site, and thus easy photograph recognition and visual representations of the images in image database is ensured. DETAILED DESCRIPTION – An INDEPENDENT CLAIM is included for an image recognition system for recognition of sights, building facades, landscapes, regions, buildings and augmented reality environments by using aerial photographs. DESCRIPTION OF DRAWING(S) – The drawing shows a flowchart of a method for constructing an image database. (Drawing includes non-English language text). Acquiring reference images from different positions in different lighting conditions according to time of day and atmospheric pressure (101) Preprocessing images (102) Extracting characteristic points of an image (103) Storing characteristic points of each site in a database (104)
