Abstract
A kind of method that real-time geographic information is merged in mobile video, picture/video to not being superimposed GPS longitudes and latitudes, real-time latitude and longitude value is obtained by GPS location instrument, picture/video for being superimposed with GPS longitudes and latitudes, pass through the longitude and latitude in method automatic identification picture/video of machine learning or pattern match, to obtain longitude and latitude numerical value, geography information title corresponding to then being obtained according to latitude and longitude value from gis database, the geography information title of acquisition finally is superimposed into mobile video to flow into and realize that real-time geographic information is effectively combined with mobile video, without other auxiliary equipments, it is clear, the real-time geographical locations information of reflecting video picture directly perceived, to reach real-time, accurately identify the geographical position of video pictures.
Description
Technical field
The present invention relates to geography information integration technology field, more particularly to one kind to merge real-time geographic letter in mobile video
The method of breath.
Background technology
At present, in mobile video acquisition, monitoring field, especially Vehicular video monitoring, robot video monitoring and nobody
In the video of machine video acquisition, there was only GPS latitude coordinates in its video pictures, it is impossible to the real-time geographic of reflecting video picture directly perceived
Location name, or need by other auxiliary equipments to identify the geographical position of video pictures.
The content of the invention
Technical problem solved by the invention in provide it is a kind of in mobile video merge real-time geographic information method,
To solve the shortcomings that in above-mentioned background technology.
Technical problem solved by the invention is realized using following technical scheme：
A kind of method that real-time geographic information is merged in mobile video, is comprised the following steps that：
1）Mobile video stream is obtained by camera first, real-time latitude and longitude value is being obtained by GPS location instrument, then according to warp
Latitude value obtained from gis database corresponding to geography information title, finally the geography information title of acquisition is folded
Add in mobile video stream and show；
2）Picture/video for being superimposed with GPS longitudes and latitudes, pass through machine learning or the method automatic identification figure of pattern match
Longitude and latitude in piece/video, to obtain longitude and latitude numerical value, then obtained according to longitude and latitude numerical value from gis database
Geography information title, finally merges picture/video with real-time geographic information title corresponding to taking, and then realizes that real-time geographic is believed
Breath is effectively combined with mobile video.
In the present invention, step 1）, step 2）In, gis database includes Baidu map database, Tengxun
Map data base, high moral map data base.
In the present invention, step 2）In, the longitude and latitude method that identification has been superimposed with GPS longitudes and latitudes picture/video is：First
The position of " east longitude, north latitude " in original picture is positioned, and image binaryzation is carried out to original picture, pretreatment picture is obtained, to pre-
Processing picture is handled, and to obtain digital profile, is being carried out image segmentation to pretreatment picture, is being obtained the digital picture of separation,
Digital value in picture is extracted by the method automatic identification of machine learning or pattern match to every digital picture, finally will
It is all to identify the digital value combination got, to obtain the latitude and longitude value of picture/video.
Beneficial effect：The present invention carries out the geographical letter of superposition in real time to video flowing caused by vehicle-mounted, robot, unmanned plane etc.
Title is ceased, without other auxiliary equipments, the real-time geographical locations information of reflecting video picture clear, directly perceived, to reach real
When, accurately identify video pictures geographical position.

Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are readily apparent from clearly, tying below
Conjunction is specifically illustrating, and the present invention is expanded on further.
A kind of method that real-time geographic information is merged in mobile video, is comprised the following steps that：
1）As shown in figure 1, obtaining mobile video stream by camera first, real-time latitude and longitude value is being obtained by GPS location instrument,
Geography information title corresponding to then being obtained according to latitude and longitude value from gis database, GIS data
Storehouse includes but is not limited to Baidu map database, Tengxun's map data base, high moral map data base, such as 114 ° 19 ' of longitude
The corresponding geographical location name in detail of 44.8 " 27 ° 48 ' 14.9 of latitudes " is " XX areas of XX cities XX main roads "；Finally by the geography information of acquisition
Title is added in mobile video stream and shown；
2）As shown in figs. 2 to 4, for being superimposed with picture/videos of GPS longitudes and latitudes, " east longitude, north latitude " is positioned first in artwork
Position on piece, and image binaryzation is carried out to original picture, pretreatment picture is obtained, as shown in figure 3, secondly, at Fig. 3
Reason, obtains digital profile, then carries out image segmentation, the numeral separated to pretreatment picture（0、1、2…）Picture, and it is right
Every digital picture passes through machine learning（Such as train numeral identification SVM models）Or the method automatic identification extraction figure of pattern match
Digital value in piece, identify that the digital value got combines by all, to obtain latitude and longitude value, such as 114 19 44.8 and 27 48
14.9；Geography information title corresponding to then being obtained according to latitude and longitude value from gis database, finally by picture/
Video merges with real-time geographic information title, and then realizes that real-time geographic information is effectively combined with mobile video.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
