-
算子 get_deep_ocr_paramget_deep_ocr_paramGetDeepOcrParamGetDeepOcrParamGetDeepOcrParamget_deep_ocr_param 返回用于单词识别的深度 OCR 模型组件句柄。通过 set_deep_ocr_paramset_deep_ocr_paramSetDeepOcrParamSetDeepOcrParamSetDeepOcrParamset_deep_ocr_param 可指定句柄、文件名或特殊字符串。特殊字符串仅允许使用 'default'"default""default""default""default""default"
和 'compact'"compact""compact""compact""compact""compact"。若为 'default'"default""default""default""default""default",则加载默认预训练的词检测组件(即 'pretrained_deep_ocr_detection.hdl'"pretrained_deep_ocr_detection.hdl""pretrained_deep_ocr_detection.hdl""pretrained_deep_ocr_detection.hdl""pretrained_deep_ocr_detection.hdl""pretrained_deep_ocr_detection.hdl"。诺为
'compact'"compact""compact""compact""compact""compact",则加载更高效的词检测组件(即 'pretrained_deep_ocr_detection_compact.hdl'"pretrained_deep_ocr_detection_compact.hdl""pretrained_deep_ocr_detection_compact.hdl""pretrained_deep_ocr_detection_compact.hdl""pretrained_deep_ocr_detection_compact.hdl""pretrained_deep_ocr_detection_compact.hdl")。若传入值为字符串,则模型将内部加载且批处理大小设为 1。
建议值:
'default'"default""default""default""default""default", 'compact'"compact""compact""compact""compact""compact", filename.
默认值:
'default'"default""default""default""default""default"

-
此参数用于为单词检测设置预定义的方位角。若要恢复使用内部方位角估算的默认行为,请将 'detection_orientation'"detection_orientation""detection_orientation""detection_orientation""detection_orientation""detection_orientation" 设置为 'auto'"auto""auto""auto""auto""auto"。

- 'detection_sort_by_line'"detection_sort_by_line""detection_sort_by_line""detection_sort_by_line""detection_sort_by_line""detection_sort_by_line"按行检测排序:
-
单词(words)根据定位单词(word)实例的方向按行排序。若需按行和列方向排序,则需将参数 'detection_sort_by_line'"detection_sort_by_line""detection_sort_by_line""detection_sort_by_line""detection_sort_by_line""detection_sort_by_line" 设置为
'false'"false""false""false""false""false"。
默认值:
'true'"true""true""true""true""true"
- 'detection_tiling'"detection_tiling""detection_tiling""detection_tiling""detection_tiling""detection_tiling"检测平铺:
-
输入图像会被自动分割为多个尺寸为 'detection_image_size'"detection_image_size""detection_image_size""detection_image_size""detection_image_size""detection_image_size" 的重叠图块,这些图块由检测组件分别处理。这使得系统能够处理远大于实际 'detection_image_size'"detection_image_size""detection_image_size""detection_image_size""detection_image_size""detection_image_size" 的图像,而无需对输入图像进行缩放。因此,当 'detection_tiling'"detection_tiling""detection_tiling""detection_tiling""detection_tiling""detection_tiling" = {'true'} 时,输入图像在处理前不会被缩放。
默认值:
'false'"false""false""false""false""false"
- 'detection_tiling_overlap'"detection_tiling_overlap""detection_tiling_overlap""detection_tiling_overlap""detection_tiling_overlap""detection_tiling_overlap"检测平铺重叠:
-

默认值:
64
- 识别组件:
-
- 'recognition_alphabet'"recognition_alphabet""recognition_alphabet""recognition_alphabet""recognition_alphabet""recognition_alphabet"识别字母表:
-
深度 OCR 模型能够识别的字符集。
它包含所有未映射到内部字母表空白字符的字符(参见参数
'recognition_alphabet_mapping'"recognition_alphabet_mapping""recognition_alphabet_mapping""recognition_alphabet_mapping""recognition_alphabet_mapping""recognition_alphabet_mapping"
和 'recognition_alphabet_internal'"recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal")。
字母表可根据需要进行修改或扩展。通过此参数修改字母表时,系统将编辑内部字母表及其映射关系,同时尽量保持内部字母表的长度不变。修改字母表后,建议使用应用程序特定数据对模型进行重新训练(参见 HDevelop 示例
deep_ocr_recognition_training_workflow.hdev)。对于先前未识别的字符,需要更多训练数据。
请注意,若内部字母表的长度发生变化,则最后的模型层需进行随机初始化,此时模型输出将为随机字符串(参见
'recognition_alphabet_internal'"recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal")。此种情况下必须重新训练模型。
- 'recognition_alphabet_internal'"recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal"识别字母表内部:
-
深度 OCR 识别组件经过训练的完整字符集。
内部字母表的首字符为特殊字符。在预训练模型中,该字符被指定为空白符(U+2800),切勿与空格混淆。空白字符不会出现在单词输出中,但可能出现在报告的候选字符列表里。该字符是必需的且不可省略。若修改内部字母表,首字符必须保持为空白字符。此外,当使用 'recognition_alphabet'"recognition_alphabet""recognition_alphabet""recognition_alphabet""recognition_alphabet""recognition_alphabet" 参数变更字母表时,系统会自动将空白符号添加至字符集。
该元组的长度对应于模型中最后一个卷积层的深度。若长度发生变化,则最后一个卷积层及其之后的所有层都需要调整大小,并可能需要重新随机初始化。此类变更后,必须重新训练模型(参见 HDevelop 示例
deep_ocr_recognition_training_workflow.hdev)。
建议使用参数 'recognition_alphabet'"recognition_alphabet""recognition_alphabet""recognition_alphabet""recognition_alphabet""recognition_alphabet" 来更改字母表,因为它会自动尝试保持内部字母表的长度。
- 'recognition_alphabet_mapping'"recognition_alphabet_mapping""recognition_alphabet_mapping""recognition_alphabet_mapping""recognition_alphabet_mapping""recognition_alphabet_mapping"识别字母映射:
-
整数索引元组。
该映射由模型在每个单词的解码步骤中应用。该映射将覆盖
'recognition_alphabet_internal'"recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal" 字符表中某个字符,用
'recognition_alphabet_internal'"recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal" 字符表中特定索引处的字符替换该字符。
在解码步骤中,每个预测结果将根据该元组中指定的索引进行映射。该元组的长度必须与
'recognition_alphabet_internal'"recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal" 元组相同。映射中每个整数索引的取值范围必须在 0 到
|'recognition_alphabet_internal'"recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal"|-1 之间。
在某些应用场景中,将特定字符映射为其他字符可能有所帮助。例如,若应用程序中仅出现数字词汇,则可将字符“O”映射为“0”字符,而无需重新训练模型。
如果某个条目包含数字 0,则在单词中对应于
'recognition_alphabet_internal'"recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal""recognition_alphabet_internal" 的字符将不会被解码。
- 'recognition_batch_size'"recognition_batch_size""recognition_batch_size""recognition_batch_size""recognition_batch_size""recognition_batch_size"识别批次大小:
-
批处理中传输至设备内存并在识别组件中并行处理的图像数量。更多详情请参阅
apply_dl_modelapply_dl_modelApplyDlModelApplyDlModelApplyDlModelapply_dl_model 参考文档中关于
'batch_size'"batch_size""batch_size""batch_size""batch_size""batch_size" 参数的说明。该参数可用于优化特定深度学习设备上 apply_deep_ocrapply_deep_ocrApplyDeepOcrApplyDeepOcrApplyDeepOcrapply_deep_ocr 的运行时性能。若识别组件需处理多个输入(单词words),并行处理多个输入可加速 apply_deep_ocrapply_deep_ocrApplyDeepOcrApplyDeepOcrApplyDeepOcrapply_deep_ocr 的执行。但需注意,增大
'recognition_batch_size'"recognition_batch_size""recognition_batch_size""recognition_batch_size""recognition_batch_size""recognition_batch_size" 将消耗更多设备内存。
默认值:
1
- 'recognition_device'"recognition_device""recognition_device""recognition_device""recognition_device""recognition_device"识别设备:
-
此参数将设置执行深度 OCR 模型识别组件的设备。更多说明请参见
'device'"device""device""device""device""device"。
默认值:
与设备 'device'"device""device""device""device""device" 相同。
- 'recognition_image_dimensions'"recognition_image_dimensions""recognition_image_dimensions""recognition_image_dimensions""recognition_image_dimensions""recognition_image_dimensions"识别图像维度:
-
元组包含图像维度('recognition_image_width'"recognition_image_width""recognition_image_width""recognition_image_width""recognition_image_width""recognition_image_width"、'recognition_image_height'"recognition_image_height""recognition_image_height""recognition_image_height""recognition_image_height""recognition_image_height"、 通道数),识别组件将处理该图像。
这意味着,网络会首先将输入图像的局部区域放大至
'recognition_image_height'"recognition_image_height""recognition_image_height""recognition_image_height""recognition_image_height""recognition_image_height",同时保持输入图像的宽高比。若放大后图像的宽度小于
'recognition_image_width'"recognition_image_width""recognition_image_width""recognition_image_width""recognition_image_width""recognition_image_width",则在图像右侧填充灰度值为 0 的区域;若放大后图像的宽度大于 'recognition_image_width'"recognition_image_width""recognition_image_width""recognition_image_width""recognition_image_width""recognition_image_width",则将图像缩放至 'recognition_image_width'"recognition_image_width""recognition_image_width""recognition_image_width""recognition_image_width""recognition_image_width"。
默认值:
[120, 32, 1]
- 'recognition_image_height'"recognition_image_height""recognition_image_height""recognition_image_height""recognition_image_height""recognition_image_height"识别图像高度:
-

使用 set_deep_ocr_paramset_deep_ocr_paramSetDeepOcrParamSetDeepOcrParamSetDeepOcrParamset_deep_ocr_param 时,可指定句柄、文件名或 'default'"default""default""default""default""default"。若为 'default'"default""default""default""default""default",则加载预训练的单词识别组件(即
'pretrained_deep_ocr_recognition.hdl'"pretrained_deep_ocr_recognition.hdl""pretrained_deep_ocr_recognition.hdl""pretrained_deep_ocr_recognition.hdl""pretrained_deep_ocr_recognition.hdl""pretrained_deep_ocr_recognition.hdl")。若给定值为字符串,则模型在内部加载,批处理大小设为 1。
建议值:
