Image and WIFI combined multimodal indoor positioning method

The invention discloses an image and WIFI combined multimodal indoor positioning method, relates to the technical field of indoor positioning and solves the technical problem of providing the method with relatively high indoor positioning precision. The method comprises the following steps of: (1), establishing an experimental environment, and establishing an image positioning position fingerprintdatabase; (2), establishing a WIFI nonuniform position fingerprint database; (3), determining an area in which a target is located; (4), determining a target position; and (5), carrying out comparison and determination and outputting the target position. According to the method, positioning precision is improved and moreover, computing quantity in a positioning phase is reduced. The method is characterized by high positioning precision, low software computing quantity and high anti-noise capacity. A real-time demand is realized on the premise of ensuring the positioning precision. 本发明公开了种基于图像与WIFI相结合的多模态室内定位方法，涉及室内定位
