New Video Dataset
Instructions for Use
A video dataset is used to manage multi-source and multi-format video data. One video dataset can be used to manage one or more videos. The dataset stores information such as the video path, video registration, and extent, facilitating the storage and management of videos. Before using video data in SuperMap iDesktopX, you need to create a new video dataset to bring the videos in. While creating the new video dataset, you can also quickly spatialize the videos via camera parameters.
- Local Video: Supports six video formats: *.mp4, *.avi, *.rmvb, *.flv, *.mov, *.ts, and also supports accessing video data encoded with DJI MISB specifications.
- Online Video: Supports accessing videos via RTSP, HLS (m3u8), RTMP, HTTP-FLV, and HTTP-MP4 protocol addresses.
Functional Entrances
- Start Tab -> New Dataset Group -> Video.
- Workspace Manager -> Datasource node context menu -> New Dataset -> Video.
- Video Map Tab -> Manage Video Group -> Add Video. (The Video Map tab is only available when the current window is a video map.)
- Video Map Tab -> Manage Video Group -> Manage Video. (The Video Map tab is only available when the current window is a video map.)
Operational Steps
- Import Video: Open the Add Video Data dialog using the first method mentioned above, then add local video or online video. The methods are as follows:
- Local video: Click the Add Local Video button in the dialog, and select one or more local videos in the pop-up dialog.
- Online video: Click the Add Online Video button in the dialog, and enter the address of the online video in the pop-up dialog. For environment configuration of online videos, please refer to the Streaming Data Service Configuration page.
- Spatialize Video: You can choose whether to spatialize the video data while creating the new video dataset. After checking this checkbox, select the camera parameter file with the same name in the same folder as the video to spatialize it. The parameters are explained as follows:
- Fixed-point Camera Parameters: Select this method for registration when the imported video is a fixed-point video. Fixed-point camera parameter registration requires manual input of the camera's position information, camera information, and field of view parameters. For details on camera parameters, please refer to Video Parameters Description.
- Parameter File Registration: To use parameter file registration, you need to input the video parameters file in the text box on the right. The program will automatically recognize the timestamp list, camera location information, camera information, and field of view parameters. For a detailed introduction to parameter file registration, please refer to Camera Parameter Registration. For details on camera parameters, please refer to Video Parameters Description.
- After completing the video import, you need to specify the coordinate system for the new video dataset in the new dataset window. Note that the specified coordinate system must be a projected coordinate system. The default coordinate system is WGS_1984/Web_Mercator. For details on other parameters, please refer to New Dataset.
