Function Description
The Calculate Bounding Rectangle is to create Bounds for the objects in the Line Dataset or Region Dataset, generate a new Region Dataset, and assign the Attributes of the objects to the generated Face objects.

Application scenario
The method can be applied to the extraction of AI Remote Sensing Imagery information, provides Bounds of interesting target vector boundaries for Object Detection training sample data, and is convenient for the extraction of information such as buildings, cultivated land and the like.
Function entrance
- Data tab-> Data Processing-> Vector-> Calculate Bounding Rectangle.
- Toolbox-> Data Processing-> Vector-> Calculate Bounding Rectangle.
Parameter Description
- Source Data: Select the Dataset to be analyzed. Only Line Dataset and Region Dataset are supported. Point Dataset is not supported.
- Result Data: Result Dataset is Region Dataset, and the attribute of the source data object will be kept in the face object corresponding to the Result Dataset.
- Decompose Subobject: When the object in the Dataset is a compound face object or a compound line object, whether to split it into sub-objects is supported.
- If the check box is checked, the Compound is split into multiple sub-objects, and a range face is generated for each sub-object;
- If this check box is not checked, Compound is used as an object to generate the range face.
Application example
The Object Detection Training Procedure needs the rectangular frame of the interest target as the label, and uses the Calculate Bounding Rectangle function to calculate the Bounds of the boundary of the interest target vector. Prepare the label data for Object Detection Generate Training Data, and get the results as shown in the following figure:
