如何使用react-native-vision-camera的Frame Processor来检测人脸？我尝试使用一个名为vision-camera-face-detector的包，但在尝试创建我的React Native CLI应用APK时失败了，是否有其他方法可以使用react-native-vision-camera的Frame Processor来检测人脸？
export default function App() {
const [cameraPermission, setCameraPermission] = useState();
useEffect(() => {
(async () => {
const cameraPermissionStatus = await Camera.requestCameraPermission();
setCameraPermission(cameraPermissionStatus);
})();
}, []);
console.log(`摄像头权限状态：${cameraPermission}`);
const devices = useCameraDevices();
const cameraDevice = devices.back;
const renderDetectorContent = () => {
if (cameraDevice && cameraPermission === 'authorized') {
return (
<Camera
style={styles.camera}
device={cameraDevice}
isActive={true}
/>
);
}
return <ActivityIndicator size="large" color="#1C6758" />;
};
return (
<View style={styles.screen}>
<SafeAreaView style={styles.saveArea}>
<View style={styles.header}>
<Text style={styles.headerText}>React Native 人脸检测器</Text>
</View>
</SafeAreaView>
{renderDetectorContent()}
</View>
);
}

我可以使用 vision-camera-face-detector 插件来检测人脸。
查看文档 https://github.com/rodgomesc/vision-camera-face-detector
以下是示例的帧处理器：
const frameProcessor = useFrameProcessor((frame) => {
'worklet';
const scannedFaces = scanFaces(frame);
runOnJS(setFaces)(scannedFaces);
}, []);
英文:
I can use the vision-camera-face-detector plugin to detect face.
See the docs https://github.com/rodgomesc/vision-camera-face-detector
Here's example the frame processor:
const frameProcessor = useFrameProcessor((frame) => {
'worklet';
const scannedFaces = scanFaces(frame);
runOnJS(setFaces)(scannedFaces);
}, []);
