Android MediaPipe 是一个用于构建实时计算机视觉管道的框架,可以处理图像、视频和其他媒体数据
- 添加依赖项:
在您的
build.gradle
文件中添加以下依赖项:
dependencies { implementation 'com.google.mediapipe:mediapipe:' }
请确保替换
为最新的 MediaPipe 版本。
- 创建 MediaPipe 图像处理管道:
首先,创建一个继承自
mp.Graph
的类,然后向其中添加图像处理节点。例如,以下代码创建了一个简单的图像处理管道,其中包括一个图像缩放和一个图像旋转节点:
import com.google.mediapipe.framework.Graph; import com.google.mediapipe.framework.Image; import com.google.mediapipe.modules.core.ImageScaler; import com.google.mediapipe.modules.core.ImageTransformer; public class ImageProcessingGraph { private Graph graph; public ImageProcessingGraph() { graph = new Graph(); // 添加图像缩放节点 graph.addNode(new ImageScaler()); // 添加图像旋转节点 graph.addNode(new ImageTransformer()); } public void processImage(Image image) { graph.run(image); } }
- 从摄像头捕获图像:
要处理来自摄像头的图像,请使用
CameraX
库。首先,添加以下依赖项到您的build.gradle
文件:
dependencies { implementation 'androidx.camera:camera-core:' implementation 'androidx.camera:camera-camera2: ' implementation 'androidx.camera:camera-lifecycle: ' }
接下来,创建一个继承自 CameraX.ViewCapture
的类,并重写 onCaptureResult
方法以处理捕获的图像:
import androidx.camera.core.ImageProxy; import androidx.camera.core.ViewCapture; import androidx.camera.core.ImageAnalysis; import androidx.camera.core.ImageProxy.PlaneProxy; public class ImageCaptureView extends ViewCapture { private ImageProcessingGraph imageProcessingGraph; public ImageCaptureView(ImageProcessingGraph imageProcessingGraph) { this.imageProcessingGraph = imageProcessingGraph; } @Override public void onCaptureResult(ImageProxy imageProxy, int cameraId) { if (imageProxy == null || imageProxy.getImage() == null) { return; } Image image = imageProxy.getImage(); // 处理图像 imageProcessingGraph.processImage(image); imageProxy.close(); } }
- 将摄像头与图像处理视图关联: 最后,将摄像头与图像处理视图关联起来。在您的 Activity 或 Fragment 中,执行以下操作:
