AI-on-the-edge-device 水表识别方案谁搞定了？

neighbour

便览hass插件  发现了一个基于ESP32-CAM的水表 AI识别方案  AI-on-the-edge-device。 https://github.com/jomjol/water-meter-system-complete 很是NICE可以通过ESP32-CAM一体化设备实现水表 电表的OCR识别 MQTT上传。

Key features

• Tensorflow Lite (TFlite) integration - including easy to use wrapper
• Inline image processing (feature detection, alignment, ROI extraction)
• Small and cheap device (3x4.5x2 cm³, < 10 EUR)
• Camera and illumination integrated
• Web surface to administrate and control
• OTA-Interface to update directly through the web interface
• Full integration into Home Assistant
• Support for Influx DB 1
• MQTT
• REST API
  

但是尝试后发现了硬件问题

手头的设备虽然明面上满足硬件需求。 但是刷入固件后报错.两个板子都是同样的故障。本身硬件自带AP MEMORY / 6404L-3SQR / 1120A / 130027G PSRAM 芯片。但是刷玩固件确提示PSRAM错误。 是我刷固件的姿势不对？还是 碰到了奸商用的假PSRAM芯片

不知道有谁弄成功过？用的是哪家店的ESP32-CAM的板子

看错误提示，你的板子没有psram，没有足够的内存来运行程序，初始化失败了

淘宝搜esp  cam  psram  就能出结果了，就是太贵了这玩意。

esp32-cam 有分, 有 psram 和 沒有 psram 版本, 你要用 有 psram 的 esp32-cam

我的ESP32-CAM 板子上焊着
AP MEMORY / 6404L-3SQR / 1120A / 130027G

在适配表  显示8M  。除非是假芯片

难道奸商家芯片？

点来点去

我有块8M的但型号不在列表内。
