Cómo abrir la cámara en modo retrato utilizando OpenCV en la aplicación Android

Creo que esto no es posible porque openCV deos no proporciona control directo de la cámara a usted, usted necesita modificar la clase de biblioteca CV CVB CameraBridgeViewBase

Puedes hacerlo. Hacer una clase JavaCamResView que extienda JavaCameraView de OPENCV. El obtendrá controles de la cámara. import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import java.util.List;
