示例1: DetectMarkers
private void DetectMarkers(WriteableBitmap bmp)
{
// Init. here because the captureSource.VideoCaptureDevice.DesiredFormat getter is not reliable and throws an Exception
if (!isInit)
{
// Init AR
arDetector.Initialize(bmp.PixelWidth, bmp.PixelHeight, Game.Camera.Near, Game.Camera.Far, new List<Marker> {slarMarker});
isInit = true;
}
// Detect
var dr = arDetector.DetectAllMarkers(bmp);
// Reused for marker highlighting
bmp.Clear();
ViewportOverlay.Source = bmp;
if (dr.HasResults)
{
var transformation = Balder.Math.Matrix.CreateTranslation(0, -5, 0) * Balder.Math.Matrix.CreateRotationX(90) * dr[0].Transformation.ToBalder();
Game.SetWorldMatrix(transformation);
// Highlight detected markers
var txt = String.Empty;
foreach (var r in dr)
{
bmp.DrawQuad((int)r.Square.P1.X, (int)r.Square.P1.Y, (int)r.Square.P2.X, (int)r.Square.P2.Y, (int)r.Square.P3.X, (int)r.Square.P3.Y, (int)r.Square.P4.X, (int)r.Square.P4.Y, Colors.Red);
txt += String.Format("{0}.Confidence = {1:0.00} ", r.Marker.Name, r.Confidence);

{
// Detected
var detectedResults = e.DetectionResults;
