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)
