Embodiment
Before address, the present invention is under the prerequisite that does not influence the normal access of multimedia resource file, utilize geographical location information and temporal information in the gps data to generate picture resource file and audio/video resource file corresponding geographical location information metadata, but in conjunction with the available extended field in the detected different multimedia resource file, be implemented in accessing geographic position information metadata in the multimedia resource file, complete transmission geographical location information metadata in multimedia resource file conversion and editor.
Below in conjunction with description of drawings implementation of the present invention, Fig. 1 has represented a kind of method that embeds geographical location information in the multimedia resource file provided by the invention.This method comprises following three steps:
For the multimedia resource file of indication in the step 1 relevant geographical location information and temporal information, be meant geographical location information and temporal information when this multimedia resource is gathered, the general GPS information when promptly multimedia resource is gathered.
For the generation of indication in the step 1 geographic position metadata corresponding with the multimedia resource type, being meant needs to consider the time of static images collection and the unicity of position, dynamically the continuity and the dynamic of audio/video collection generate corresponding with it geographical location information metadata based on its different requirement.Fig. 4 has provided the concrete steps that generate the geographical location information metadata:
Can expand in the picture typelib 123 storage picture file form and corresponding file suffix thereof commonly used, for example corresponding JPG, JPEG of JPEG, JPE or JFIF suffix, the corresponding GIF of GIF, TIFF corresponding TIF, TIFF, the corresponding PNG of PNG.Can expand and also store picture format and corresponding file character code thereof commonly used in the picture typelib 123, for example the image file opening code of JPEG is 0xFFD8, and the file character code of PNG is 0x89504E470D0A1A0A.In addition, can expand picture typelib 123 can expand to support new picture format.
Can expand storage audio/video file layout and corresponding file suffix thereof commonly used in the audio/video typelib 124, for example, AVI corresponding A VI suffix, ASF corresponding A SF, WMV, WMA, the corresponding 3GP of 3GP.Can expand and also store audio/video file layout and corresponding file character code thereof commonly used in the picture typelib 123, for example the file character code of AVI is fourCC " RIFF ", the file character code of ASF is that 128 ASF_Header_Object value is " 75B22630668E11CFA6D900AA0062CE6C ", the file character code of 3GP be that its file header bag identifies " ftyp ".In addition, can expand audio/video typelib 124 can expand to support new audio/video file layout.
The geographical location information metadata that step 13 generates is meant collection of resources longitude, latitude, sea level elevation, date, time, acquisition angles and the version information constantly of static images type.
The geographical location information metadata that step 14 generates, be meant resource file for the audio/video type, need to consider the sequential and the dynamic of continuous acquisition, described metadata comprises: gather longitude, latitude, sea level elevation, date, time, acquisition angles, version information, movement velocity and the angle of advancing of the zero hour, and several relative longitudes with respect to the zero hour in the gatherer process, latitude, sea level elevation, relative time, acquisition angles, speed of related movement and the relative angle of advancing relatively relatively relatively.
Step 141 refer to described in the step 11 can establish the mode of fixed intervals, constantly obtain geographical location information and temporal information, promptly constantly obtain GPS information;
Step 142 refers to calculate with respect to metadata generation last time constantly, at present latitude, the precision of variation and the height of variation that changes;
Step 143 refer to calculate with respect to last time metadata generate overall amplitude of variation constantly, concrete computing formula as shown in Equation 1:
Wherein Δ x is the surface distance of the longitude correspondence of variation, and Δ y is the surface distance of the latitude correspondence of variation, and Δ h is the distance of the height correspondence of variation.
The amplitude of variation of setting is decided according to concrete the application, for example, and 5 meters, 10 meters, 20 meters, 50 meters, 100 meters, 200 meters.
For the geographical location information metadata that generates in step 13 and 14, the present invention is divided into Memory Reference metadata among the tissue that two parts carry out data structure: the GPSH (GPS Header) with it; The relative metadata of storage among the GPSI (GPSInformation).
Metadata for the geographical location information of picture/mb-type only needs a GPSH to get final product.
For the metadata of the geographical location information of audio/video type, it needs a GPSH and a plurality of GPSI.The metadata store of geographical location information of gathering the zero hour is in GPSH, and a series of relative geographical location information metadata store in the gatherer process is in a series of GPSI.
