Prepare the Video Data |
To use video-related services, you first need to prepare video data with spatial information. You need to use SuperMap iDesktopX to create a video data set. One or more videos can be imported into the video data set, and the path, registration, range and other information of the video can be stored to facilitate the storage and management of the video.
SuperMap iServer is currently able to publish videos shot by cameras with fixed point attitudes. The supported video types and protocols are as follows:
Creating a video dataset is a two-step process:
1. Import video
2. Video spatialization
SuperMap iDesktopX provides four ways to create video data sets. For details about how to import video, see Importing Video
Before the video shot by the camera is overlaid with GIS data for mapping and combined analysis, the video needs to be spatialized, so that the image coordinates are converted into geospatial coordinates, the geospatial scope of the video is calibrated, and the mapping relationship between the video image space and the geospatial is constructed.
SuperMap iDesktopX provides two video registration capabilities for video spatialization, including calibration registration and camera parameter registration
After the above steps are completed, the workspace is saved, and the video data preparation is completed.
