Description

The operator read_descriptor_modelread_descriptor_modelReadDescriptorModelReadDescriptorModelread_descriptor_model reads a descriptor model, which has been written with write_descriptor_modelwrite_descriptor_modelWriteDescriptorModelWriteDescriptorModelwrite_descriptor_model, from the file FileNameFileNameFileNamefileNamefile_name. The default HALCON file extension for the descriptor model is 'dsm'.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters

FileNameFileNameFileNamefileNamefile_name (input_control)  filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)

File name.

File extension: .dsm

ModelIDModelIDModelIDmodelIDmodel_id (output_control)  descriptor_model → HDescriptorModel, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the model.
