PP-LCNet_x0_25_textline_ori_onnx

Introduction

The text line orientation classification module primarily distinguishes the orientation of text lines and corrects them using post-processing. In processes such as document scanning and license/certificate photography, to capture clearer images, the capture device may be rotated, resulting in text lines in various orientations. Standard OCR pipelines cannot handle such data well. By utilizing image classification technology, the orientation of text lines can be predetermined and adjusted, thereby enhancing the accuracy of OCR processing. The key accuracy metrics are as follow:

Model Usage

Install Dependencies

pip install -U paddleocr
pip install -U onnxruntime-gpu

CLI Usage

paddleocr textline_orientation_classification -i ./demo.jpg --model_name PP-LCNet_x0_25_textline_ori --engine onnxruntime

Python API Usage

from paddleocr import TextLineOrientationClassification

model = TextLineOrientationClassification(
    model_name="PP-LCNet_x0_25_textline_ori",
    engine="onnxruntime",
)
output = model.predict("./demo.jpg", batch_size=1)
for res in output:
    res.print()
    res.save_to_json(save_path="./output/res.json")
