+## 基于EasyPR的车牌识别android实现
+
+EasyPR4Android，基于[EasyPR](https://github.com/liuruoze/EasyPR)1.6的android实现, 提供编译好的[mrcar.apk](https://github.com/imistyrain/EasyPR4Android/releases)安装运行demo.
+
+### 效果图
+
+特性：摄像头实时预览
+
+![live](cameralive.png)
+
+### 编译和运行：
+
+环境: android studio3.5开发实现，ndk版本为R16b，OpenCV版本为3.2，android SDK版本为28，最低要求21。
+
+* 1.下载并配置[android studio 3.5](http://www.android-studio.org/)
+
+* 2.配置NDK16b[ndk r16b](http://blog.csdn.net/shuzfan/article/details/52690554)
+
+* 3.编译并运行，也可以直接下载编译好的[apk](https://github.com/imistyrain/EasyPR4Android/releases)安装使用
+
+本项目定义了三个Activity, 其中
+
+* [PhotoActivity](app/src/main/java/yanyu/com/mrcar/PhotoActivity.java)是从图片和系统相机抓取图片进行识别
+
+* [CVCameraActivity](app/src/main/java/yanyu/com/mrcar/CVCameraActivity.java)是用OpenCV的JavaCameraView实时识别，由于OpenCV实现的限制，其只能用于横屏，虽然也有trick能使其支持竖屏，但会有性能损失，为此产生了第三种
+
+* [CameraActivity](app/src/main/java/yanyu/com/mrcar/CameraActivity.java)原始摄像头实时识别，抓取NV21数据送到jni中，并将其抓换成RGB数据进行处理，其支持竖屏识别。
+
