|
| 37 |
+
|
| 38 |
+
2. PaddleOCR
|
| 39 |
+
|
| 40 |

Install the latest version of the PaddleOCR inference package from PyPI:
|
| 41 |
+
|
| 42 |
+

```
|
| 45 |
+
|
| 46 |
+
|
| 47 |
+
### Model Usage
|
| 48 |
+
|
| 49 |
+
You can quickly experience the functionality with a single command:
|
| 50 |
+
|
| 51 |
+
```bash
|
| 52 |
+
paddleocr layout_detection \
|
| 53 |
+
--model_name PicoDet_layout_1x \
|
| 54 |
+
-i https://cdn-uploads.huggingface.co/production/uploads/63d7b8ee07cd1aa3c49a2026/-oU2IpNLcA0gTMJ34wDBR.png
|
| 55 |
+
```
|
| 56 |
+
|
| 57 |
+
You can also integrate the model inference of the layout detection module into your project. Before running the following code, please download the sample image to your local machine.
|
| 58 |
+
|
| 59 |
+
```python
|
| 60 |
+
from paddleocr import LayoutDetection
|
| 61 |
+
|
| 62 |
+
model = LayoutDetection(model_name="PicoDet_layout_1x")
|
| 63 |
+
output = model.predict("-oU2IpNLcA0gTMJ34wDBR.png", batch_size=1, layout_nms=True)
|
| 64 |
+
for res in output:
|
| 65 |
+
res.print()
|
| 66 |
+
res.save_to_img(save_path="./output/")
|
| 67 |
+
res.save_to_json(save_path="./output/res.json")
|
| 68 |
+
```
|
| 69 |
+
|
| 70 |
+
After running, the obtained result is as follows:
|
| 71 |
+
|
| 72 |
+
```json
|
| 73 |
+

|

+
### Pipeline Usage
|
| 83 |
+
|
| 84 |
+
The ability of a single model is limited. But the pipeline consists of several models can provide more capacity to resolve difficult problems in real-world scenJust a few lines of code can experience the inference of the pipelinearios.
|
| 85 |
+
|
| 86 |
+
#### PP-TableMagic (table_recognition_v2)
|
| 87 |
+
|
| 88 |
+
The General Table Recognition v2 pipeline (PP-TableMagic) is designed to tackle table recognition tasks, identifying tables in images and outputting them in HTML format. PP-TableMagic includes the following 8 modules:
|
| 89 |
+
|
| 90 |
+
* Table Structure Recognition Module
|
| 91 |
+
* Table Classification Module
|
| 92 |
+
* Table Cell Detection Module
|
| 93 |
+
* Text Detection Module
|
| 94 |
+
* Text Recognition Module
|
| 95 |
+
* Layout Region Detection Module (optional)
|
| 96 |
+
* Document Image Orientation Classification Module (optional)
|
| 97 |
+
* Text Image Unwarping Module (optional)
|
| 98 |
+
|
| 99 |
+
You can quickly experience the PP-TableMagic pipeline with a single command.
|
| 100 |
+
|
| 101 |
+
```bash
|
| 102 |
+
paddleocr table_recognition_v2 -i https://cdn-uploads.huggingface.co/production/uploads/63d7b8ee07cd1aa3c49a2026/-oU2IpNLcA0gTMJ34wDBR.png \
|
| 103 |
+
--layout_detection_model_name PicoDet_layout_1x \
|
| 104 |
+
--use_doc_orientation_classify False \
|
| 105 |
+
--use_doc_unwarping False \
|
| 106 |
+
--save_path ./output \
|
| 107 |
+
--device gpu:0
|
| 108 |
+
|
| 109 |
+
```
|
| 110 |
+
|
| 111 |
+
You can also integrate the PP-TableMagic pipeline into your project. Before running the following code, please download the sample image to your local machine.
|
| 112 |
+
|
| 113 |
+
```python
|
| 114 |
+
from paddleocr import TableRecognitionPipelineV2
|
| 115 |
+
|
| 116 |
+
pipeline = TableRecognitionPipelineV2(
|
| 117 |
+
layout_detection_model_name=PicoDet_layout_1x,
|
| 118 |
+
use_doc_orientation_classify=False, # Use use_doc_orientation_classify to enable/disable document orientation classification model
|
| 119 |
+
use_doc_unwarping=False, # Use use_doc_unwarping to enable/disable document unwarping module
|
| 120 |
+
device="gpu:0", # Use device to specify GPU for model inference
|
| 121 |
+
)
|
| 122 |
+
|
| 123 |
+
output = pipeline.predict("-oU2IpNLcA0gTMJ34wDBR.png")
|
| 124 |
+
for res in output:
|
| 125 |
+
res.print() ## Print the predicted structured output
|
| 126 |
+
res.save_to_img("./output/")
|
| 127 |
+
res.save_to_xlsx("./output/")
|
| 128 |
+
res.save_to_html("./output/")
|
| 129 |
+
res.save_to_json("./output/")
|
| 130 |
+
```
|
| 131 |
+
|
| 132 |
+
The default model used in pipeline is `PP-DocLayout-L`, so it is needed that specifing to `PicoDet_layout_1x` by argument `layout_detection_model_name`. And you can also use the local model file by argument `layout_detection_model_dir`. For details about usage command and descriptions of parameters, please refer to the [Document](https://paddlepaddle.github.io/PaddleOCR/main/en/version3.x/pipeline_usage/table_recognition_v2.html#2-quick-start).
