推荐基于ESP32-CAM 的30元低成本AI-on-the-edge-device 抄表系统

neighbour

基于各种协议智能仪表。APP抓包的水电气表抄表方案已经很多了。但是针对传统仪表主要是脉冲累加和图像识别。前者麻烦精度不高，后者一直没有找到更简化的方案。
现在我家的燃气表用的就是图像识别方案。用了一个1080的P的网络摄像图抓图，提交nr流程利用百度识图ocr.返回数据通过MQTT传到hass

现在已经能稳定运行，但是还是有一些问题
1.成本高一个摄像头接近150.（2020年好像ESP2CAM还没流通）；
2.因为镜头畸变光线不均匀百度OCR识别位数一旦超过5位，识别率就会降低。 分位识别要多次调用接口。免费额度根本不够用。
所以一直想找个本地现场的OCR方案。这个方案稳定后，也想弄一下家里的水表。但因为成本和需求的问题也一直没弄，直到后来发现了ESP32CAM 这个东西决定开始折腾水表。但是百度OCR的额度被我的燃气表用完了，就一直搜寻本地方案。 查了一下hass官网，居然得来全不费功夫。居然有两套成熟的OCR方案
一个是 https://github.com/jomjol/AI-on-the-edge-device
一个是https://github.com/nohn/watermeter
而AI-on-the-edge-device更是在ESP32CAM 边缘侧完成全部功能。而另外一个则需要在容器中运行。
AI-on-the-edge-device文档非常详细https://jomjol.github.io/AI-on-the-edge-device-docs/。而且向导式配置程序用气来太简单了。但是我中间也踩了一些坑，和大家絮叨一下。

1.首先ESP32CAM 必须有4M+的PSRAM 。我之前买的包含了8M的PSRAM的ESPCAM能刷进去程序，但是找不到全部的PSRAM，不知道是不是碰到了奸商。
后来买的4M PSRAM用自带的底座刷程序，不管用webtools还是客户端都刷不进去程序。最后用USB2TTL才刷进去。回头还要试试之前那个8MB的ESPCAM，是不是也是这个原因刷不进去程序。
2.ESP32CAM的摄像头直接拧不动，一定要用刀小心翼翼的把固定胶刮掉才能旋转摄像头对焦。旋出拉近，旋进拉远；3.摄像头一定要稳固固定。否则出现偏离会影响识别（程序设置的时候有标定物，开始还以为能细微调节呢。 实际上不可以。）
4.数字表包含小数位的。可以在Postprocessing Individual Parameters- Decimal Shift 里进行设置！
5.如果识别偏差太大，可以在Maximum Rate Value 里设置清除误差（要根据实际采集频率，和用量来决定最大误差）‘
6.如果设置了5，因为断电或者其他导致两次识别误差比较大没有更新数值。可以web页面手动设置previous value，也可以通过接口放到nr里或者hassos的手动输入界面。方便手动矫正。
7.程序有的地方有些小Bug，比如说在清空模拟量ROI后，无法新建。可以手动修改CONFIG.INI 来恢复。


AI-on-the-edge-device 还是灰常不错的。水表识别了，电表和气表更是不在话下。 但是这个软件的前作我也很喜欢，放在docker下可以用任意图片来识别。但是不知道什么原因在我的docker中运行会报，有时间再看看。毕竟任意图片识别自由度更大一些！

识别的结果图。数字转一半也能识别出来！

楼主你好，请问下我这使用这个项目识别电表，发现拍下的图片有像素偏移（旋转几度，边缘有白边），你有遇到过这样的情况吗

happyfoeverq

亲测，ZAVE的“ESP32 CAM+GC2640摄像头”这款的主板PSRAM可用

mark一下准备买这个

norikohxb

你的抄表摄像头距离水表的玻璃面是多少厘米？采用什么型号？能否赐教？

norikohxb

摄像头怎么选择？要买微距的对吗？参数上有什么要求请赐教
