Abstract

The invention provides a localizable video file format which can integrates video information, audio information and space locating information into a whole and facilitates the quick search of late-stage space locating information. Based on the video format, the invention discloses a method for collecting data of the localizable video file format in real time, which comprises the following steps: the video information and the audio information are collected by a camera and a microphone and the space locating information is received by a GPS serial receiver; a video collecting platform performs compressed encoding on the collected video information and the video information and extraction on corresponding parameters of the space locating information in real time according to audio and video coding parameters provided by a user and the selected space locating parameter information, marks timestamps on the collected video information, the collected video information and the space locating information at corresponding position of a time axis of the video collecting platform according to the collecting time of the three information, and finally the three information is stored in a hard disk by the localizable video file format.

Description

technical field

[0001] The invention relates to a positionable video file format integrating video and audio information and spatial information and a method for collecting (acquisition) file data (information) of the positionable video file format. Background technique

[0002] As we all know, the geographic space depicted in the video has a strong sense of reality, can provide easy-to-understand geographic spatial information, makes people use information more naturally, and does not require complex geometric modeling, so in recent years multimedia technology has begun to cause GIS The attention of the field has become a new development direction in the field of GIS. However, the video itself does not have the location and attribute information (spatial information) of the spatial object, so it can only be stored and called as a kind of attribute information of the spatial entity, and it is difficult to make a connection between the spatial reference system of GIS and the ...
