描述

算子 write_data_code_2d_modelwrite_data_code_2d_modelWriteDataCode2dModelWriteDataCode2dModelWriteDataCode2dModelwrite_data_code_2d_model writes a 2D data code model, which was created by create_data_code_2d_modelcreate_data_code_2d_modelCreateDataCode2dModelCreateDataCode2dModelCreateDataCode2dModelcreate_data_code_2d_model, into a file with the name FileNameFileNameFileNameFileNamefileNamefile_name. This facilitates creating an identical copy of the saved model in a later session with the operator read_data_code_2d_modelread_data_code_2d_modelReadDataCode2dModelReadDataCode2dModelReadDataCode2dModelread_data_code_2d_model。The default HALCON file extension for the 2D data code model is 'dcm'. The handle of the model to write is passed in DataCodeHandleDataCodeHandleDataCodeHandleDataCodeHandledataCodeHandledata_code_handle。

For an explanation of the concept of the 2D data code reader see the introduction of chapter Identification / Data Code。

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。

参数

示例（HDevelop）

* This example demonstrates how a trained model can be saved for
* a future session

* Create a model for reading Data matrix ECC 200 codes
create_data_code_2d_model ('Data Matrix ECC 200', [], [], DataCodeHandle)
* Read a training image
read_image (Image, 'datacode/ecc200/ecc200_cpu_007')
* Train the model with the symbol in the image
find_data_code_2d (Image, SymbolXLDs, DataCodeHandle, 'train', 'all', \
                   ResultHandles, DecodedDataStrings)
* Write the model into a file
write_data_code_2d_model (DataCodeHandle, 'ecc200_trained_model.dcm')
* Clear the model
clear_data_code_2d_model (DataCodeHandle)

结果

算子 write_data_code_2d_modelwrite_data_code_2d_modelWriteDataCode2dModelWriteDataCode2dModelWriteDataCode2dModelwrite_data_code_2d_model 返回值 2 ( H_MSG_TRUE) if the passed handle is valid and if the model can be written into the named file.否则，将抛出异常。
