Sensor | Matterport SDK
Usage of the SDK constitutes your agreement with the Matterport SDK Agreement. Email developers@matterport.com with any questions.

Our Sensor system allows for generating spatial queries to understand a Matterport digital twin. By utilizing and setting up Sources around the scene, some questions that can be answered are:

  • "what things are currently visible on screen?"
  • "what things are near me?"

where "things" can be Mattertag posts, sweeps, arbitrary locations (that you choose), or any combination of those.

Types

Methods

Types

BoxVolume

BoxVolume: object

Type declaration

  • center: Vector3

    The center position of the box.

  • orientation: Orientation

    The orientation of the box. The rotations are applied in yaw, pitch, then roll order.

  • size: Vector3

    The length, width, and depth of the box volume.

CylinderVolume

CylinderVolume: object

Type declaration

  • basePoint: Vector3

    The point which defines the position (base) from which the height in the +Y, and radius in the XZ-plane are relative to.

  • height: number

    The height of the cylinder.

  • radius: number

    The radius of the cylinder.

SensorReading

SensorReading: object

Information about the Source as read by the Sensor.

Type declaration

  • direction: Vector3

    The world-space direction from the sensor to the source.

  • distance: number

    The distance between the sensor and the source.

  • distanceSquared: number

    The squared distance from the sensor to the source.

  • inRange: boolean

    The sensor is currently within the broadcast range of the source.

  • inView: boolean

    The sensor is within the source's broadcast range and the sensor has clear line of sight to the source.

SourceOptions

SourceOptions: object

Additional userData to associate with an ISource when creating it. This is a free dictionary that can contain any key/values deemed necessary.

Type declaration

  • userData: UserData

SphereVolume

SphereVolume: object

Type declaration

  • origin: Vector3

    The origin of the sphere.

  • radius: number

    The distance from origin of the sphere volume.

Methods

createSensor

  • Create an ISensor which can sense and provide information about ISource.

    const sensor = await mpSdk.Sensor.createSensor(mpSdk.Sensor.SensorType.CAMERA);
// add sources from calls to `Sensor.createSource()`
sensor.addSource(...sources);
// start listening for changes to the sensor's readings
sensor.readings.subscribe({
  onAdded(source, reading) {
    console.log(source.userData.id, 'has a reading of', reading);
  },
  onUpdated(source, reading) {
    console.log(source.userData.id, 'has an updated reading');
    if (reading.inRange) {
      console.log(source.userData.id, 'is currently in range');
      if (reading.inView) {
        console.log('... and currently visible on screen');
      }
    }
  }
});

    Parameters

    Returns Promise<Sensor.ISensor>

createSource

  • Create a spherical ISource which can be sensed by an ISensor.
    A shallow copy of options.userData is applied to the Source upon creation.

    Omitting options.origin will default the source's volume.origin to { x: 0, y: 0, z: 0 }.
    Omitting options.radius will default the source's volume.radius to Infinity.

    const sources: Array<Sensor.ISource<Sensor.SphereVolume, { id: string }>> = await Promise.all([
  mpSdk.Sensor.createSource(mpSdk.Sensor.SourceType.SPHERE, {
    origin: { x: 1, y: 2, z: 3 },
    radius: 20,
    userData: {
      id: 'sphere-source-1',
    },
  }),
  mpSdk.Sensor.createSource(mpSdk.Sensor.SourceType.SPHERE, {
    radius: 4,
    userData: {
      id: 'sphere-source-2',
    },
  }),
]);
// attach to a sensor previously created with `Sensor.createSensor()`
sensor.addSource(...sources);

    Type parameters

    • UserData: Record<string, unknown>

    Parameters

    Returns Promise<Sensor.ISource<Sensor.SphereVolume, UserData>>

  • Create an box shaped ISource which can be sensed by an ISensor.
    A shallow copy of options.userData is applied to the Source upon creation.

    Omitting options.center will default the source's volume.center to { x: 0, y: 0, z: 0 }.
    Omitting options.size will default the source's volume.size to { x: Infinity, y: Infinity, z: Infinity }. Omitting options.orientation will default the source's volume.orientatin to { yaw: 0, pitch: 0, roll: 0 }.

    const sources: Array<Sensor.ISource<Sensor.BoxVolume, { id: string }>> = await Promise.all([
