大家好，我是Java1234_小锋老师，分享一套锋哥原创的基于YOLO26的车牌识别+智慧停车场系统(深度学习+目标检测+微信小程序+LPRNet+CCPD++FastAPI+Vue3) 。

项目介绍

针对传统停车场依赖人工发卡、车牌识别精度受光照和拍摄角度影响较大、车主缴费流程繁琐等问题，本文设计并实现了一套基于 YOLO26+LPRNet 深度学习的智慧停车场管理系统。系统采用检测与识别解耦的两阶段方案：首先使用在中国城市停车车牌数据集 CCPD 上训练得到的 YOLO26-Pose 模型定位车牌并回归四个角点，再对车牌区域进行透视矫正与双层牌拆分，最后由轻量级 LPRNet 结合 CTC 贪心解码输出车牌号码。业务系统采用 FastAPI 构建 REST 接口，Vue3 与 Element Plus 实现管理员后台，微信小程序实现车主端。管理员可完成入场识别、出场识别、视频抽帧择优、车主车辆审核、区域车位维护、收费规则配置和数据看板统计；车主可通过用户名密码注册登录、绑定车牌、查询余位与停车记录，并在出口扫描缴费二维码完成模拟支付。数据库采用 MySQL 8，库名为 db_smart_parking，核心表均以 t_ 开头。测试表明，系统能够完成从车牌识别、车位分配、计费到扫码缴费的闭环业务，图片识别耗时约数百毫秒，满足本科毕业设计对完整性、可用性和工程规范性的要求。
