Name

close_ocvT_close_ocvCloseOcvCloseOcvclose_ocv — Clear an OCV tool.

Signature

close_ocv( : : OCVHandle : )

Description

close_ocvclose_ocvCloseOcvCloseOcvCloseOcvclose_ocv closes an open OCV tool and frees the memory. The OCV tool has been created using create_ocv_projcreate_ocv_projCreateOcvProjCreateOcvProjCreateOcvProjcreate_ocv_proj or read_ocvread_ocvReadOcvReadOcvReadOcvread_ocv. The handle is after this call no longer valid.

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 modifies the state of the following input parameter:

OCVHandleOCVHandleOCVHandleOCVHandleOCVHandleocvhandle

During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

Parameters

OCVHandleOCVHandleOCVHandleOCVHandleOCVHandleocvhandle (input_control, state is modified) ocv → (handle)

Handle of the OCV tool which has to be freed.

Example (C++ (HALCON 5.0-10.0))

read_ocv("ocv_file",&ocv_handle);
for (i=0; i<1000; i++)
{
  grab_image_async(&Image,fg_handle,-1);
  reduce_domain(Image,ROI,&Pattern);
  do_ocv_simple(Pattern,ocv_handle,"A",
                "true","true","false","true",10,
                &Quality);
}
close_ocv(ocv_handle);

Result

close_ocvclose_ocvCloseOcvCloseOcvCloseOcvclose_ocv returns 2 (H_MSG_TRUE), if the handle is valid. Otherwise, an exception is raised.
