You can use LEADTOOLS Imaging Pro SDK technology inside your application.

The Xamarin Camera Control allows you to tap into a mobile device's camera and control its camera functions. The AutoCapture class allows you to add auto capture capabilities to your Xamarin application.

Here is a tutorial on how to implement the camera control.

Below is a C# snippet that shows how to implement the AutoCapture class.

public LiveCapturePage()
{
InitializeComponent();
leadCamera.CameraOptions.AutoRotateImage = true;
autoCapture.CaptureMethod = AutoCapture.AutoCaptureMethod.DocumentDetection;
leadCamera.FrameReceived += LeadCamera_FrameReceived;
}
private void LeadCamera_FrameReceived(Leadtools.Camera.Xamarin.FrameHandlerEventArgs e)
{
using (RasterImage _img = e.Image.Clone())
{
if (autoCapture.CheckHoldStability(_img))
{
leadCamera.FrameReceived -= LeadCamera_FrameReceived;
// Code to handle the auto detected image
}
}
}
