In the present embodiment, dynamic video data are provided by the video monitoring equipment of movement, location when geographical location information is the video monitoring equipment capture video of described movement, its locator meams comprises one or more the combination in GPS, architecture, WIFI location.
In step S103, static video data and dynamic video data are mapped on the correspondence position of electronic chart according to geographical location information.
Wherein, on a position, one group of static video data or dynamic data be may only shine upon, one group of static data and many group dynamic datas also may have been shone upon simultaneously.
In step S104, receive the query demand of user's input.
Conventionally, user's inquiry need to comprise the path between a certain geographic position, two geographic position, or the peripheral extent based on a certain geographic position is inquired about.As, the north gate of certain university, the north gate of Cong Mou university is to the path between certain teaching building, or the scenery of Mount Taishan periphery.
In step S105, according to query demand, select or form preferred plan, and playing.
Wherein, for query demand, first judge whether the scheme of satisfying the demand; If had, directly select as preferred plan; If no, be connected and form preferred plan according to geographical location information with described dynamic video data according to existing described static video data.
Such as, query demand is the path of 2 kms between two geographic position, and the scope that wherein just has a section 100 meters does not have fixing video monitoring equipment, static video data cannot be provided, but the dynamic video data that have these 100 meters of sections, when preferred plan is provided, these dynamic video data of 100 meters can be inserted in the static video data of 2 kms of breakpoint, according to geographical location information, be connected and form preferred plan.
Conventionally, when static data and dynamic data are present in same geographic position simultaneously, preferentially select static data, because its image quality is relatively stable, secure.And many group dynamic datas while existing simultaneously when same geographic position, preferentially select the dynamic data that resolution is high, the more picture of high-quality is provided.
Embodiment 2
Refer to Fig. 2, be depicted as the schematic diagram of the roaming system based on electronic chart in the present invention.Shown in roaming system comprise: fixing video monitoring equipment, mobile video monitoring equipment, electronic chart, enquiry module, scheme provide module and video playback module.
In details of the words, fixing video monitoring equipment, refers to the video monitoring equipment that is fixed on ad-hoc location, for static video data is provided.The position at fixing video monitoring equipment place is depended in the geographic position of described static video data, and described fixed position refers to the positional informations such as longitude and latitude that the administrative authority by public security or city, scenic spot, residential block carries out unified management, puts on record.
Mobile video monitoring equipment, refers to find a view car or hand-held picture pick-up device, smart mobile phone etc., for dynamic video data is provided.The position at mobile video monitoring equipment place is depended in the geographic position of described dynamic video data, conventionally by modes such as GPS, base station, WIFI, positions, and this locating information and dynamic video data are preserved in the lump.
Electronic chart, for visualized map is provided, and receives above-mentioned static video data and dynamic video data, according to geographical location information separately, is mapped on corresponding position.
Enquiry module, for receiving the query demand of user's input.
Conventionally, user's inquiry need to comprise the path between a certain geographic position, two geographic position, or the peripheral extent based on a certain geographic position is inquired about.As, the railway station outlet in certain city, from the path between Dao Mou shopping centre, railway station, the campus of Huo Mou university.
Scheme provides module, for according to query demand, selects or form the video data of preferred plan.
Wherein, if for the demand of inquiring about, the existing scheme that can satisfy the demand, directly selects as preferred plan.If there is no the scheme that can satisfy the demand, according to existing static video, be connected and form preferred plan according to geographical location information with dynamic video.
Video playback module, the preferred plan that provides module to provide for playing described scheme.
Wherein, enquiry module and video playback module, can be also to can be used as in the hand-held devices such as smart mobile phone that software downloads to user as guide's equipment of renting separately.
Video data is divided into static state with dynamic according to its source, and presses the stereoprojection of geographical location information difference on electronic chart, and become preferred plan according to geographical location information sets, for user's selection, improved the sense of reality of roaming.
The present invention is by static state and dynamic video data, stereoprojection is on electronic chart, become after map vector, satellite map, virtual paster map, form " three-dimensional video-frequency map " of overall importance, effectively increased quantity of information, improve the sense of reality, opened up the data and application new model of electronic chart.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
