The invention discloses a realistic hand-drawn map segmentation method and device, and an intelligent tourism guide implementation method and system. The segmentation method comprises steps of firstly determining the position of a realistic hand-drawn map in a third-party map, then obtaining the resolution of the realistic hand-drawn map according to longitudinal and latitudinal coordinate values at the top left corner and the bottom right corner of the realistic hand-drawn map, further obtaining the maximal map level of the realistic hand-drawn map, and then equally segmenting the realistic hand-drawn map according to different map levels and storing segmented parts in the same file. The method segments the whole map, so that a big map is segmented into small maps to be stored, and when a user uses the map, the loading efficiency of the map in the loading process is improved. The invention also tackles defects at present that many map service providers cannot provide proper maps for Chinese outbound travelers.
