图像文字识别
（结尾附样例展示）
以下为与图像通用识别的 Python示例代码*
#!/usr/bin/env python
#coding=utf-8from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkocr.request.v20191230.RecognizeCharacterRequest import RecognizeCharacterRequestclient = AcsClient('<accessKeyId>', '<accessSecret>', 'cn-shanghai')request = RecognizeCharacterRequest()
request.set_accept_format('json')request.set_MinHeight("10")
request.set_OutputProbability("true")
request.set_ImageURL("https://viapi-test.oss-cn-shanghai.aliyuncs.com/demo-center/ocr/RecognizeCharacter.jpg")response = client.do_action_with_exception(request)
# python2: print(response)
print(str(response, encoding='utf-8'))功能描述
RecognizeCharacter可以识别图像中文字内容和文字区域坐标，适用于多场景图像文字识别。
输入限制
请求格式：JPEG、JPG、PNG、BMP、GIF。
图像大小：图像大小不超过3M。
图像分辨率：不限制图片分辨率，但图片分辨率太高可能会导致API识别超时，超时时间为5秒。
URL地址中不能包含中文字符。
调试
您可以在OpenAPI Explorer中直接运行该接口，免去您计算签名的困扰。运行成功后，OpenAPI Explorer可以自动生成SDK代码示例。
JSON模式
- MInHeight是Integer类型为必选，其是指图片中文字的最小高度，单位为像素（下见代码块第三行）
- OutputProbability是Booleanl类型为必选，其是指是否输出文字框的概率，取值为true或者false(下见代码块第六行）
