Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.
[0036] The first embodiment of the present invention, such as image 3 As shown, the device of the present invention is a terminal 35, which includes a camera module 10, a basic positioning module 15, an accessory positioning module 20 and a microprocessor module 30. The camera module 10 contains a storage unit 11. Among them, the basic positioning module 15 provides the X, Y, and Z coordinate values of the terminal 35 in the geodetic coordinate system through the GPS global satellite positioning module 16, and the accessory positioning module 20 through the multiple degrees of freedom including the acceleration sensor 21 and the geomagnetic sensor 22 The sensing system gives the direction angle φ and the tilt angle θ of the terminal 35 in the above-mentioned coordinate system. The microprocessor module 30 calculates the angles α, β, γ between the coordi...

The invention discloses a terminal service method for providing geographic information tags for digital photos. The terminal service method comprises an internally-arranged basic positioning module, namely a GPS global positioning module, and also comprises the terminal of an additional positioning module. Steps followed by the terminal to provide the geographic information tags for the digital photos comprise a step of obtaining terminal coordinate values, a step of calculating the direction angle and the inclination angle of the terminal, a step of calculating space vectors of terminal coordinates, a step of extracting interesting point coordinates, a step of calculating space vectors of the interesting point coordinates, a step of comparing the space vectors, a step of marking the geographic information tags and a step of storing the information of the geographic information tags. The added geographic information accurately embodies the photographing purpose information of a terminal controller, namely a photographer. Based on the purpose information, a user can more effectively collect, sort and manage the digital photos. In a picture share service based on networks, by utilizing the information, a more-pertinent picture share service based on the geographic information tags can be developed.
Description
Technical field [0001] The invention relates to the technical field of electronic navigation and geographic information technology, in particular to a terminal service method for providing geographic information tags for digital photos. Background technique [0002] With the development of digital multimedia technology, digital cameras and digital photos taken by them have become increasingly popular. As we all know, the images recorded in photographs in photographic activities are always associated with specific places or places. Therefore, the user needs to remember the name or feature of a specific place represented by a certain photo after taking a photo. Not only that, with the development of network technology, digital photo network sharing is becoming increasingly popular on the basis of browser technology. Often, photographers need to attach geographic information tags to their digital photos when sharing on the Internet. Through geographic information tags, users can ...
