这就是标题里“ESP32Cam Arduino底层 + Python版本OpenCV”的真实逻辑： ESP32-CAM 只做轻量级图像采集与预处理（裁剪、灰度、缩放、JPEG压缩），把原始图像流高效传给 PC；真正的特征提取、比对、阈值判断全部交给 Python + OpenCV + dlib / face_recognition / insightface 完成。
ESP32Cam的8MB Flash + 520KB RAM，连加载一个轻量级MobileNetv1都要抠着用，更别说OpenCV-python动辄200MB的依赖链。 这个项目真正的价值，恰恰在于 主动放弃在端侧做识别 ：Arduino只干三件事——精准控摄像头、稳定抓图、可靠传图；所有图像处理、人脸检测、特征比对，全交给PC端Python+OpenCV完成。
