解决方法:

修改openCVLibrary中CameraBridgeViewBase中的onEnterStartedState()方法，方法里面 connectCamera(int width, int height),参数就是要输出的camera分辨率大小（长和宽）

connectCamera代码如下：

    /**
     * This method is invoked shall perform concrete operation to initialize the camera.
     * CONTRACT: as a result of this method variables mFrameWidth and mFrameHeight MUST be
     * initialized with the size of the Camera frames that will be delivered to external processor.
     *
     * @param width  - the width of this SurfaceView
     * @param height - the height of this SurfaceView
     */
    protected abstract boolean connectCamera(int width, int height);
