描述
create_deep_ocrcreate_deep_ocrCreateDeepOcrCreateDeepOcrCreateDeepOcrcreate_deep_ocr creates a Deep OCR model out of pretrained components
and returns its handle in DeepOcrHandleDeepOcrHandleDeepOcrHandleDeepOcrHandledeepOcrHandledeep_ocr_handle.
The handle states all parameters needed to run an inference.
A Deep OCR model usually consists of two components that are searched in the
directory $HALCONROOT/dl/ by default:
The following options may be set using GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and according
GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value:
- 'mode'"mode""mode""mode""mode""mode":
-
Specify a mode and with it, which component is
executed. Supported values:
- 'detection'"detection""detection""detection""detection""detection":
Perform only the detection part.
Hence, the model will merely localize the word regions within the image.
- 'recognition'"recognition""recognition""recognition""recognition""recognition":
Perform only the recognition part.
Hence, the model requires that the image contains solely a tight crop of
the word.
- 'auto'"auto""auto""auto""auto""auto":
Perform both parts, detection of the words and their
recognition.
Default:
'auto'"auto""auto""auto""auto""auto".
The character set, which the model can recognize through its recognition
component, can be retrieved using get_deep_ocr_paramget_deep_ocr_paramGetDeepOcrParamGetDeepOcrParamGetDeepOcrParamget_deep_ocr_param with
'recognition_alphabet'"recognition_alphabet""recognition_alphabet""recognition_alphabet""recognition_alphabet""recognition_alphabet".

运行信息
- 多线程类型:可重入(与非独占操作符并行运行)。
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。
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.
