### 🌰 Minimal Reproducible Example (最小可复现问题的Demo)

import os
import cv2
import numpy as np
import time
from paddleocr import PPStructure, save_structure_res
from paddle.utils import try_import
from PIL import Image

ocr_engine = PPStructure(table=False, ocr=True, show_log=True)

save_folder = '/work/output'
img_path = '/work/input/GWHT20230046592BG1.pdf'

fitz = try_import("fitz")
imgs = []

with fitz.open(img_path) as pdf:
    for pg in range(pdf.page_count):
        page = pdf[pg]
        mat = fitz.Matrix(2, 2)
        pm = page.get_pixmap(matrix=mat, alpha=False)

# 如果宽度或高度超过2000像素，则不放大图像
        if pm.width > 2000 or pm.height > 2000:
            pm = page.get_pixmap(matrix=fitz.Matrix(1, 1), alpha=False)

img = Image.frombytes("RGB", [pm.width, pm.height], pm.samples)
        img = cv2.cvtColor(np.array(img), cv2.COLOR_RGB2BGR)
        imgs.append(img)

# 处理每一页图像并计算OCR时间
for index, img in enumerate(imgs):
    start_time = time.time()  # 记录开始时间

result = ocr_engine(img)
    save_structure_res(result, save_folder, os.path.basename(img_path).split('.')[0], index)

# 计算用时
    elapsed_time = time.time() - start_time
    print(f"Time taken for page {index + 1}: {elapsed_time:.2f} seconds")
