read_deep_ocrT_read_deep_ocrReadDeepOcrReadDeepOcrread_deep_ocr (算子)

名称

read_deep_ocrT_read_deep_ocrReadDeepOcrReadDeepOcrread_deep_ocr — 从文件中读取深度 OCR 模型。

签名

描述

算子 read_deep_ocrread_deep_ocrReadDeepOcrReadDeepOcrReadDeepOcrread_deep_ocr reads a Deep OCR model. Such models have to be in the HALCON format. As a result, the handle DeepOcrHandleDeepOcrHandleDeepOcrHandleDeepOcrHandledeepOcrHandledeep_ocr_handle is returned.

The model is loaded from the file FileNameFileNameFileNameFileNamefileNamefile_name. This file is thereby searched in the directory $HALCONROOT/dl/ as well as in the currently used directory. The default HALCON file extension for Deep OCR models is '.hdo'".hdo"".hdo"".hdo"".hdo"".hdo".

Please note that the values of runtime specific parameters are not written to file, see write_deep_ocrwrite_deep_ocrWriteDeepOcrWriteDeepOcrWriteDeepOcrwrite_deep_ocr。As a consequence when reading a model these parameters are initialized with their default value, see get_deep_ocr_paramget_deep_ocr_paramGetDeepOcrParamGetDeepOcrParamGetDeepOcrParamget_deep_ocr_param。

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。

此算子返回一个句柄。请注意，即使该句柄被用作特定算子的输入参数，这些算子仍可能改变此句柄类型的实例状态。

参数

结果
