The Video Layer Properties panel is used to manage video attributes. Right-click the video layer in the Layer Manager and select Properties to display the Video Layer Properties panel on the right side of the application, showing related video information.
Video List
Displays multiple video items in the video dataset. Click any video item in the list to switch videos on the map and view other parameter information in the Video Layer Properties panel.
Video Parameters
Use the toolbar buttons (Add, Set Camera Parameters, Delete, Import/Export Video Parameter File, Import Camera Parameters) to manage video parameter files.
- Add: Creates video parameters for different timestamps or angles. Click to add a record for the video's current time.
- Set Camera Parameters: Manually input camera intrinsic/extrinsic parameters for video registration when known. Select a record and click to configure:
- Camera Intrinsic Parameters:
- FovX: Horizontal field of view (angle).
- FovY: Vertical field of view (angle).
- Cx: Horizontal pixel offset between image center and origin (theoretical value: half of video width).
- Cy: Vertical pixel offset between image center and origin (theoretical value: half of video height).
- Extrinsic Parameters:
- Roll: Angle between aircraft symmetry plane and vertical plane of longitudinal axis (positive for right deviation).
- Pitch: Angle between camera axis and horizontal plane (0° horizontal, negative for downward tilt, -90° for nadir).
- Yaw: Angle between shooting direction and true north (0° north, -180° south, increasing clockwise).
- X/Y/Z: Longitude/latitude coordinates and absolute/relative altitude of camera position.
- Camera Intrinsic Parameters:
- Import Camera Parameters: Import camera parameters to automatically generate timestamped records. For details, see Camera Parameter Registration.
- Import/Export: Import/export all parameter records in the video parameters list.
- Delete: Remove video parameter records.
Video Valid Bounds
Set visible boundaries to improve video registration accuracy. Adjust when video contains distant scenery or horizons to avoid excessive distortion.
- Min X/Y: Set left/bottom boundaries (default: 0).
- Max X/Y: Set right/top boundaries (default: video dimensions).
PTZ Position
Configure PTZ positions for multi-angle video registration:
- Pan: Horizontal rotation angle.
- Tilt: Vertical tilt angle.
- Zoom: Focal length adjustment.
