read_surface_modelT_read_surface_modelReadSurfaceModelReadSurfaceModelread_surface_model (Operator)
Name
read_surface_modelT_read_surface_modelReadSurfaceModelReadSurfaceModelread_surface_model — Read a surface model from a file.
Signature
def read_surface_model(file_name: str) -> HHandle
Description
The operator read_surface_modelread_surface_modelReadSurfaceModelReadSurfaceModelread_surface_model reads the surface model, which has
been written with write_surface_modelwrite_surface_modelWriteSurfaceModelWriteSurfaceModelwrite_surface_model, from the file
FileNameFileNameFileNamefileNamefile_name.
The handle of the surface model is returned in SurfaceModelIDSurfaceModelIDSurfaceModelIDsurfaceModelIDsurface_model_id.
If no absolute path is given in FileNameFileNameFileNamefileNamefile_name, the file is searched
in the current directory of the HALCON process.
The default HALCON file extension for the surface model (SFM) file is
'sfm'.
If no file named FileNameFileNameFileNamefileNamefile_name exists, the default file extension is
appended to FileNameFileNameFileNamefileNamefile_name.
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*)
Name of the SFM file.
File extension:
.sfm
SurfaceModelIDSurfaceModelIDSurfaceModelIDsurfaceModelIDsurface_model_id (output_control) surface_model → HSurfaceModel, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of the read surface model.
Result
read_surface_modelread_surface_modelReadSurfaceModelReadSurfaceModelread_surface_model returns 2 (
H_MSG_TRUE)
if all parameters are
correct and the file can be read.
If the file is not a surface model file, the error 9506 is raised.
If the file has a version that can not be read by this version of HALCON,
the error 9507 is raised.
If necessary, an exception is raised.
