Cesium 铯传感器

我在我的应用程序中添加了一个简单的矩形传感器

addRectangularSensor() {
    this.viewer.scene.primitives.removeAll();
    var rectangularPyramidSensor = new CesiumSensorVolumes.RectangularPyramidSensorVolume();
    rectangularPyramidSensor.modelMatrix = this.getModelMatrix();
    rectangularPyramidSensor.radius = 50000.0;
    rectangularPyramidSensor.xHalfAngle = Cesium.Math.toRadians(45);
    rectangularPyramidSensor.yHalfAngle = Cesium.Math.toRadians(30);

    rectangularPyramidSensor.lateralSurfaceMaterial = Cesium.Material.fromType('Color');
    rectangularPyramidSensor.lateralSurfaceMaterial.uniforms.color = new Cesium.Color(0.0, 1.0, 1.0, 0.5);
    rectangularPyramidSensor.intersectionColor = Cesium.Color.YELLOW

    rectangularPyramidSensor.debugShowCrossingPoints = true;
    rectangularPyramidSensor.showIntersection = true;
    console.log('rectangularPyramidSensor', rectangularPyramidSensor)
    console.log('rectangularPyramidSensor.modelMatrix', rectangularPyramidSensor.modelMatrix)
    this.viewer.scene.primitives.add(rectangularPyramidSensor);
    console.log('this.viewer.scene.primitives', this.viewer.scene.primitives)
},
  getModelMatrix() {
  var longitude = Cesium.Math.toRadians(34.862923);
   var latitude = Cesium.Math.toRadians(31.996851);
   var altitude = 2000.0;
   var clock = 0.0;
   var cone =  Cesium.Math.toRadians(15.0);
   // var cone =  0.0;
   var twist = 0.0;
  var ellipsoid = this.viewer.scene.globe.ellipsoid;
  var location = ellipsoid.cartographicToCartesian(new Cesium.Cartographic(longitude, latitude, altitude));
  var modelMatrix = Cesium.Transforms.northEastDownToFixedFrame(location);
  var orientation = Cesium.Matrix3.multiply(
                      Cesium.Matrix3.multiply(Cesium.Matrix3.fromRotationZ(clock), Cesium.Matrix3.fromRotationY(cone), new Cesium.Matrix3()),
                      Cesium.Matrix3.fromRotationX(twist), new Cesium.Matrix3()
                    );
  const globe = this.viewer.scene.globe;
  
  return Cesium.Matrix4.multiply(modelMatrix, Cesium.Matrix4.fromRotationTranslation(orientation, Cesium.Cartesian3.ZERO), new Cesium.Matrix4());
},

如何获得该传感器的交互坐标（角点） 我想画一些关于这个传感器的图像或视频
