preparation example Construction

[0031] The present invention is a kind of multimedia synthesis method based on user trajectory, the process is as follows figure 1 shown, including the following steps:

[0032] Step 1: Establish the index structure of the spatial region data;

[0033] Divide the target scene into several spatial regions according to the geospatial region and function, and the geometric model of the spatial region is the set of spatial positions of the midpoint of the spatial region and the radius of the spatial region. If the spatial region has relevant video, audio, and text information, then establish a mapping relationship between the relevant video, audio, and text information and the geographic location in the spatial region, and construct an index structure for the spatial region data, which can be retrieved through a given spatial region to the multimedia material corresponding to the spatial region containing the region;

[0034] Step 2: establishing an index structure of surveillan...

Embodiment

[0048] In this paper, the present invention is described by taking a travel scene as an example. Since tourist scenes rarely have the phenomenon of different scenic spots at different altitudes at the same latitude and longitude coordinates, this paper simplifies the spatial area and expresses it as a plane area, that is, the set of latitude and longitude coordinates and the radius of the area; simplifies the spatial location and expresses it with plane coordinates, that is, the latitude and longitude coordinates . In step 1, the entire scenic area is divided according to the area of ​​the scenic spot, and the object of the introduction of the scenic spot may include the introduction of the entire scenic spot and the introduction of the scenic spot. All of them can use a geographic area to represent the target of the described scenic spot, for example, a circular closed area can be used to describe a scenic spot, and a polygon can be used to describe the entire scenic spot.

Abstract

The invention discloses a multimedia integration method based on user trajectory, which comprises the following steps: 1, establishing an index structure of space region data in the scene; 2, establishing an index structure for monitoring the video data; 3, collecting the user moving trajectory; 4, receiving user-shot picture data; 5, searching multimedia content according to the user moving trajectory; and 6, integrating the multimedia content. With the user moving trajectory in the scene as a centre, the new digital content is formed by associating with the relevant multimedia data. The user behaviour track is realized in the security field, the invention has wide application in the aspects, such as creating a personalized tourist commemorative video in a scenery area.

Description

technical field [0001] The invention relates to a multimedia synthesis method based on a user track, and belongs to the cross technical field of positioning and video image processing. Background technique [0002] In recent years, with the rapid development of communication electronics and multimedia technology, more and more image recording devices, such as video cameras and digital cameras, have been continuously improved in performance, while their prices have been continuously reduced, and they have gradually become common consumer goods in people's daily life. These can record people's activities in a specific scene at any time or in real time, and play a huge role in improving people's quality of life and improving public safety. [0003] On the basis of a large number of existing multimedia data, centering on the user's movement trajectory in the scene, combining relevant multimedia data to form new digital content has broad application prospects in many fields. For...
