前言
软硬件支持
- nodered；
- 需要用到的节点：
- node-red-contrib-wfwatch
- node-red-contrib-image-output
- node-red-contrib-http-request
- node-red-contrib-bizwechat
实现步骤：
- 创建应用
例：https://aip.baidubce.com/rest/2.0/image-classify/v1/animal?access_token=获取到的access_token
- 图片的获取
自行查看摄像头抓图地址
由于我的摄像头是EASYN，暂时没有找到抓图地址，并且使用群辉的surveillance station抓图也暂时没有成功，所以我使用的方法是靠Easyn摄像头自动侦测移动拍照，照片通过保存到指定的FTP服务器文件夹（FTP服务器我使用的是群辉，下次补充过程），使用wfwatch节点监控FTP文件夹是否有新图片产生，对新生成的图片进行识别并推送结果。

上图把狗识别出猫是因为返回结果里没有狗这个字，而出现了一次猫这个字导致的。所以需要经过更多的数据采集来完善判断。
