In step 021, when carrying out retrieval and inquisition to information database, the object retrieved the need for being given according to user
Keyword obscured in information database, query composition.Also, retrieval and inquisition is correlation inquiry, such as, by one
The name of infrastructure management company director, you can associate out range of information, including this person be responsible for Tenement's title, this can be seen
CCTV camera point position, other information of the infrastructure management company of infrastructure management company etc..
Step 022：According to the retrieval result for obtaining, video camera point position and/or affiliated partner are carried out in original video
Positioning, and view shows or list provides the particular location of video camera point position and/or affiliated partner in original video or map.
Retrieval and inquisition is that affiliated partner in correlation inquiry, step 022 refers to being closed with inquiry of being obtained according to correlation inquiry
The related object of key word, including the object such as road, building.
In step 022, the qualified video camera point position and/or affiliated partner that will can be returned are prominent in original video
It has been shown that, and Overlapping display other relevant informations, information needed is obtained so as to quick.
In step 022, when needing to be shown video camera point position and/or affiliated partner on map, recall in advance
Electronic map, the particular geographic location of video camera point position and/or affiliated partner is mapped out, and link and video camera point
Position and/or the related specific video of affiliated partner.The characteristic distributions of video camera point position and/or affiliated partner are checked with reference to map,
And can independently select rapidly to recall real-time video by mouse or touch screen gesture operation, or carry out reviewing video record or control cloud
Platform etc. is operated.
It should be appreciated that electronic map is the electronic map of video camera point position their location in original video.
It should be appreciated that other are provided similar to the real-time original video of monitor video suitable for another embodiment of the present invention
The video retrieval method based on information database, such as TV station's fixing point position captured in real-time program video camera in section
Visually frequently.
Video retrieval method based on information database provided in an embodiment of the present invention, by according to original video content and
Information database is set up in geographical position, and retrieval and inquisition is carried out to the association content in information database according to actual demand, according to
The Query Result for obtaining, is monitored the positioning of video camera point position in monitor video, and view shows or list is given at regarding
The mode of the particular location in frequency picture or map, makes the retrieval and inquisition of monitor video more precisely, quickly, effectively increases and regards
Frequency recall precision.Especially during people's police handle a case, people's police can be by video retrieval method provided in an embodiment of the present invention
Quick obtaining is handled a case the important video information of needs, and locating and displaying is carried out in original video or electronic map, is effectively improved
The efficiency of investigating and prosecuting of case.
On the basis of above-described embodiment, another embodiment of the present invention is related to existing original video, such as the Forbidden City etc. to build
Identify the original video of class.As shown in Fig. 2 the video retrieval method step based on information database in another embodiment of the present invention
It is as follows：
Step 01：Information database is set up according to the corresponding original video content in video camera point position and geographical position.
In step 01, original video is existing original video, such as the Forbidden City original video.Included in existing original video
Information carry out classification storage according to the difference of addition objectification, and associated with affiliated video camera point position, i.e. information database
In video camera point position can correspond to multiple addition objects, such as, and occur in same video camera point position comprising road, palace,
The video pictures of multiple addition objects such as shopping shop.Meanwhile, the addition object comprising same video information can also correspond to multiple and take the photograph
Camera point position, such as, in the Forbidden City original video, Palace of Heavenly Purity is likely to appear in the video pictures of multiple video camera point positions.
Step 02：The association content in information database is retrieved on demand, and locating and displaying is carried out to retrieval result.
It is further comprising the steps of in step 02：
Step 021：According to actual demand, retrieval and inquisition is carried out to the association content in information database.
In step 021, when carrying out retrieval and inquisition to information database, the key retrieved the need for being given according to user
Word is obscured in information database, query composition, also, retrieval and inquisition is correlation inquiry.
In step 021, when carrying out fuzzy query to keyword, fuzziness can be artificially set, fuzziness also can be zero, i.e.,
Directly accurate inquiry.During fuzziness low order section, represent that inquiry fuzziness is lower, i.e., closer to accurate inquiry；Fuzziness high-stage
When, represent that inquiry fuzziness is higher.Fog-level linear growth trend of the fuzziness from low order section to high-stage.
For example, when the Field Inquiry of " imperial concubine's imperial sleeping palace " is carried out by the Forbidden City original video, when set fuzziness as
During high-stage, the video information relevant with the field such as " imperial concubine ", " imperial sleeping palace ", " imperial concubine's imperial sleeping palace " is inquired about；When setting fuzziness as low
During the stage, the video information relevant with " imperial concubine's imperial sleeping palace " field is only inquired about.
Step 022：According to the retrieval result for obtaining, video camera point position and/or affiliated partner are carried out in original video
Positioning, and view shows or list provides the particular location of video camera point position and/or affiliated partner in original video or map.
