J'ai déjà fait quelque chose de similaire. Voici comment procéder: vous devez d'abord localiser les points par rapport au rectangle de la vue, par exemple si vous voulez placer un chapeau, la première tête de pointe et le rectangle relatif du chapeau en fonction de CameraView, puis placez le chapeau sur cette coordonnée. C'est la partie facile. La partie difficile est de sauver l'image. Pour cela, vous devez enregistrer la largeur et la longueur de CameraView et des autocollants et leur emplacement sur CameraView. Ensuite, vous capturez l'image et obtenez un bitmap/Drawable. Vous obtiendrez probablement des tailles différentes pour le bitmap produit que CameraView, vous devez donc recalculer la coordonnée des autocollants sur cette bitmap en fonction de w/h pour CameraView et fusionner les autocollants sur les nouvelles coordonnées, puis enregistrez-le. Ce n'est pas facile mais c'est possible comme je l'ai fait.
Voici mon code (dans mon autocollant cas était placé dans le centre de l'image):

quelle application cool! Il n'y a pas de moyen facile d'accomplir cette tâche à un tel niveau. Je crois que cette équipe utilise une bibliothèque de détection de visage plus avancée que celle intégrée. –
@AlexCohn Merci Pour regarder sur cela .... Je cherche cette bibliothèque ou un autre mais cette tâche n'est pas facile pour moi. –
Le point de départ évident est le projet OpenCV. –
