java调用百度人脸识别(已测试)

有成品和配套论文

由于电脑人脸签到的项目比较急,所以花了45分下载了【SSM调用百度人脸识别demo】。结果下载下来没啥了用,最后还是花了时间去解决,为了方便后来者。特把代码贴上

有疑问可站内消息我

目标效果:path1和path2的图片进行对比(这里为了简化,设置同一个图片,期望识别结果100分)

百度提示(80分就算同一人)

运行后结果:

{"error_code":0,"error_msg":"SUCCESS","log_id":12019494001,"timestamp":1602949391,"cached":0,"result":{"score":100,"face_list":[{"face_token":"19d4a0a9588f186f19ee0206c9b184ca"},{"face_token":"19d4a0a9588f186f19ee0206c9b184ca"}]}}

符合期望

代码中红色部分,需要自己去申请百度账号key
