Flutter 预览摄像头中的人脸检测
[英]Face Detection in Preview Camera Feed on Flutter
问题描述
How do we "draw a square" on detected faces on camera preview feed in Flutter?
我们如何在 Flutter 中的相机预览提要中检测到的面部上“画一个正方形”？ Is there a cross platform solution to this?是否有跨平台解决方案？
Flutter provides a Camera Plugin , but is there a way for us to draw a square box detecting faces on the preview feed ? Flutter提供了一个Camera Plugin ，但是有没有办法让我们在preview feed上画一个检测人脸的方框呢？ Any thoughts on this please?请问有什么想法吗？

SOMETHING LIKE THIS EXAMPLE CAMERA PREVIEW FEED像这个示例相机预览提要

Firstly, get the image data.首先，获取图像数据。 This can be done by either using the camera plugin's output, or even directly communicate with the SurfaceView/TextureView.这可以通过使用camera插件的 output 来完成，甚至可以直接与 SurfaceView/TextureView 通信。
Secondly, run face detection algorithm.其次，运行人脸检测算法。 If you do not need cross-platform, https://medium.flutterdevs.com/face-detection-in-flutter-2af14455b90d?gi=f5ead7c6d7c9 MLKit sounds good.如果不需要跨平台， https://medium.flutterdevs.com/face-detection-in-flutter-2af14455b90d?gi=f5ead7c6d7c9 MLKit 听起来不错。 If needing cross-platform, you can use Rust algorithms like https://github.com/atomashpolskiy/rustface and bind Rust code to Flutter via https://github.com/fzyzcjy/flutter_rust_bridge .如果需要跨平台，可以使用Rust算法，如https://github.com/atomashpolskiy/rustface ，通过https://github.com/fzyzcjy/flutter_rust_bridge将Rust代码绑定到Flutter Or, use C++ face detection algorithms and bind to Flutter (though setup may be a bit harder).或者，使用 C++ 面部检测算法并绑定到 Flutter（尽管设置可能有点困难）。
Lastly, once you know the face, draw a box around it.最后，一旦你知道了这张脸，就在它周围画一个方框。 For example, Container widget.例如， Container小部件。
