smatg's Introduction

SMATG

一个大四时自己想来搞的项目；
树莓派，瑞士军刀扩展板，通过opencv，写了几个脚本。自己训练人脸识别样本，可以达到一定的识别率。
最终封装功能：
- 识别到指定人脸，识别成功自动拍照，AR投影指示框
- 检测到人脸，框起来，通过按键选择是否加入到样本库

原型到产品的距离

AR微型投影是用OLED加分光棱镜实现的
树莓派算不过来
电源及小型化

原理

AR视觉原理

虚拟影像和真实影像的叠加
- 使用分光棱镜，采用的是50：50的，即真实场景和AR场景1：1叠加
投影屏离眼睛太近无法聚焦的问题
- 在OLED屏和分光棱镜之间放置一个凸透镜，调整距离即可调整好焦距

人脸识别和检测原理

几个opencv的API调用
基于opencv-2.9.4
