目标图片如图：

使用如下脚本：

def ocr_to_word(source_image, target_image):

    ocr = PaddleOCR(use_angle_cls=True, lang="ch", use_gpu=False,
                    det_model_dir=os.path.join(OCR_MODEL_PATH, "ch_PP-OCRv3_det_infer"),
                    cls_model_dir=os.path.join(OCR_MODEL_PATH, "ch_ppocr_mobile_v2.0_cls_infer"),
                    rec_model_dir=os.path.join(OCR_MODEL_PATH, "ch_PP-OCRv3_rec_infer"))

    result = ocr.ocr(source_image, cls=True)

    for idx in range(len(result)):
        res = result[idx]
        for line in res:
            print(line)

    # 显示结果

    result = result[0]
    image = Image.open(source_image).convert('RGB')
    boxes = [line[0] for line in result]
    txts = [line[1][0] for line in result]
    scores = [line[1][1] for line in result]
    im_show = draw_ocr(image, boxes, txts, scores, font_path=f'{OCR_MODEL_PATH}/simfang.ttf')
    im_show = Image.fromarray(im_show)
    im_show.save(target_image)

控制台输出：
