Feature Description
Block network adjustment is a high-precision geometric correction method. It calculates the orientation parameters of satellite images based on tie points measured within a stereo or planar block network and ground control points through adjustment. This method can effectively eliminate systematic errors and random errors, making it suitable for scenarios involving large-area image coverage or multi-image mosaic processing.
SuperMap iDesktopX version 11i(2023) and later supports this feature.
Parameter Description
| Parameter Name | Parameter Interpretation | Parameter Type |
| Dataset |
Displays the dataset containing the images used for adjustment processing. This field is read-only. |
DatasetMosaic |
| Input Image Type | Selects the image type for adjustment processing. The default is Panchromatic Image. It can also be switched to Multispectral Image, Forward-looking Image, Rear-view Image, or Front View and Rear View Image based on the specific situation. | ComboBoxImageType |
| Refer To The Adjustment File |
Based on existing adjustment file information, makes the edge matching accuracy and plane accuracy of this adjustment result closer to the accuracy of the existing results. Use the Add and Delete buttons in the toolbar to conveniently manage multiple reference adjustment files. The refer to the adjustment file is generated by the previous block network adjustment. If executing a production workflow, uses the Refer to the adjustment file parameter from Generate Connection Points, and this field is read-only. |
ReferenceFileData |
| Adjustment Mode |
Selects the specific adjustment solution method. The default is Constraining Tie Point Elevation.
|
BlockAdjustmentType |
| Result RPC Path |
Displays the storage path for the Result RPC. This field is read-only. For workflows related to DOM production, the default value is Set the Image Path中的Processing path/Adjustment/BlockAdjustment. For workflows related to DSM production, the default value is Set Image Path (dsm/dem)中的Processing path/Adjustment/BlockAdjustment. |
File |
| Default Adjustment File Path |
The adjustment file is used to store information about the images and RPC file paths participating in this adjustment. The storage format is *.csv.
|
Boolean |
| Adjustment File Path |
Available after unchecking Default adjustment file path. Specifies the path for storing the resulting adjustment file. |
