Description

read_metrology_modelread_metrology_modelReadMetrologyModelReadMetrologyModelReadMetrologyModel reads a metrology model, which has been written to file with write_metrology_modelwrite_metrology_modelWriteMetrologyModelWriteMetrologyModelWriteMetrologyModel, from the file FileNameFileNameFileNameFileNamefileName. The default HALCON file extension for a metrology model is 'mtr'. The values contained in the read metrology model are stored in a metrology model with the handle MetrologyHandleMetrologyHandleMetrologyHandleMetrologyHandlemetrologyHandle. Access to the parameters of the metrology model is possible, e.g., with the operator get_metrology_object_paramget_metrology_object_paramGetMetrologyObjectParamGetMetrologyObjectParamGetMetrologyObjectParam or get_metrology_object_fuzzy_paramget_metrology_object_fuzzy_paramGetMetrologyObjectFuzzyParamGetMetrologyObjectFuzzyParamGetMetrologyObjectFuzzyParam.

For an explanation of the concept of 2D metrology see the introduction of chapter 2D Metrology.

Execution Information

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

FileNameFileNameFileNameFileNamefileName (input_control)  filename.read → HTupleHTupleHtuple (string) (string) (HString) (char*)

File name.

File extension: .mtr

MetrologyHandleMetrologyHandleMetrologyHandleMetrologyHandlemetrologyHandle (output_control)  metrology_model → HMetrologyModel, HTupleHTupleHtuple (integer) (IntPtr) (Hlong) (Hlong)

Handle of the metrology model.

Result

If the parameters are valid, the operator read_metrology_modelread_metrology_modelReadMetrologyModelReadMetrologyModelReadMetrologyModel returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
