## HyperLPR3-License Plate Recognition Android SDK [中文文档](README_CH.md) High performance license plate recognition based on deep learning HyperLPR Android SDK implementation. ### Source Code Project If you need to learn about the build steps in the source code of the project, you can go : [HyperLPR](https://github.com/szad670401/HyperLPR). ### Supporting Platform - Android: arm64-v8a、armeabi-v7a ### Add Dependency Add Jitpack dependencies to your Gradle configuration ```java allprojects { repositories { ... maven { url 'https://jitpack.io' } } } ``` Add dependencies in build.gradle for projects where you need hyperlpr ```java dependencies { implementation 'com.github.HyperInspire:hyperlpr3-android-sdk:1.0.3' } ``` ### How to Use #### Initialize HyperLPR Before implementing the license plate recognition algorithm, the initialization function needs to be executed, and the storage read and write permissions need to be opened in advance. Initialization is performed only once, usually when the program is started. ```Java // License plate recognition algorithm configuration parameters HyperLPRParameter parameter = new HyperLPRParameter() .setDetLevel(HyperLPR3.DETECT_LEVEL_LOW) .setMaxNum(1) .setRecConfidenceThreshold(0.85f); // Initialization (performed only once) HyperLPR3.getInstance().init(this, parameter); ``` #### License plate recognition on an image Bitmap is used as an example for license plate recognition ```Java // Use Bitmap as picture parameter for license plate recognition Plate[] plates = HyperLPR3.getInstance().plateRecognition(bitmap, HyperLPR3.CAMERA_ROTATION_0, HyperLPR3.STREAM_BGRA); for (Plate plate: plates) { // Print the detected license plate number Log.i(TAG, plate.getCode()); } ``` #### License plate recognition on an steam License plate recognition using camera stream or file stream ```Java // License plate recognition using a stream of NV21 Plate[] plates = HyperLPR3.getInstance().plateRecognition(data, previewSize.height, previewSize.width, HyperLPR3.CAMERA_ROTATION_270, HyperLPR3.STREAM_YUV_NV21); ``` #### Note The Android-SDK of hyperlpr is currently in the testing phase. If you encounter any problems during use, please raise your questions in issues. PR welcome.
