参数签名

描述

read_ocvread_ocvReadOcvReadOcvReadOcvread_ocv reads an OCV tool from file. The tool will contain the same information that it contained when saving it with write_ocvwrite_ocvWriteOcvWriteOcvWriteOcvwrite_ocv. After reading the tool the training can be completed for those patterns which have not been trained so far. Otherwise a pattern comparison can be applied directly by calling do_ocv_simpledo_ocv_simpleDoOcvSimpleDoOcvSimpleDoOcvSimpledo_ocv_simple.

As extension '.ocv' is used. If this extension is not given with the file name it will be added automatically.

运行信息

• 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.

参数表

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);

结果

read_ocvread_ocvReadOcvReadOcvReadOcvread_ocv returns 2 ( H_MSG_TRUE) , if the file is correct. Otherwise, an exception is raised.
