python EasyOCR库如何使用

本篇内容介绍了"python EasyOCR库如何使用"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

说明

1、EasyOCR是一个用python编写的OCR三方库。可以在python中调用，用来识别图像中的文字，并输出为文本。

2、支持80多种语言的识别，识别精度高，甚至要超过PaddleOCR。

安装命令

pip install easyocr

代码实现

import easyocr #设置识别中英文两种语言reader = easyocr.Reader(["ch_sim","en"], gpu = False) # need to run only once to load model into memoryresult = reader.readtext(r"d:Desktop4A34A16F-6B12-4ffc-88C6-FC86E4DF6912.png", detail = 0)print(result)

实例扩展：

图文提取的代码

from pathlib import Pathimport easyocrfile_url = r"识别图片.jpg"    # 需识别的图片split_symbol = " "          # 默认空格为分隔符row_space = 15              # 默认字符高度为15px，当识别出来的字符间距超过这个数值时会换行。def make_reader():    # 将模型加载到内存中。模型文件地址 C:Users用户.EasyOCRmodel    reader = easyocr.Reader(["ch_sim", "en"])    return readerdef change_to_character(file_url, reader, split_symbol=" ", row_space=15, save_dir="."):    with open(file_url, "rb") as img:        img_b = img.read()    result = reader.readtext(img_b)    result.sort(key=lambda x: x[0][0][1])  # 按竖直方向，进行排序==>进行分行处理。    # for i in result:    #     print(i)    # print("="*100)    # 按行进行分组    content = []    item = [result[0]]  # 首先放入第一个元素    for i in result[1:]:        if row_space >= i[0][0][1] - item[-1][0][0][1] >= 0:            item.append(i)        else:            content.append(item)            item = [i]    content.append(item)    filemane = Path(file_url).name.split(".")[0]    with open(f"{save_dir}/{filemane}.txt", "w", encoding="utf8") as t:        for i in content:                     # i 为每一行的内容            i.sort(key=lambda x: x[0][0][0])  # 对每行的内容进行先后排序            for r in i:                # print(r)                t.write(r[1] + split_symbol)            t.write("")    return contentif __name__ == "__main__":    change_to_character(file_url,  make_reader())
