Use buildings and terrain around you on Android SDK (Kotlin/Java) | ARCore

Stay organized with collections Save and categorize content based on your preferences.

The Streetscape Geometry APIs provide the geometry of terrain, buildings, or other structures in a scene. The geometry can be used for occlusion, rendering, or placing AR content via hit-test APIs. Streetscape Geometry data is obtained through Google Street View imagery.

The geospatial_java sample app demonstrates how to obtain and render Streetscape Geometries.

To use Streetscape Geometry, you'll need to set up the Geospatial API in your project. Follow instructions on Enabling the Geospatial API to set up the Geospatial API.

The Geospatial API obtains Streetscape Geometry data when the GeospatialMode is set to GeospatialMode.ENABLED and StreetscapeGeometryMode is set to StreetscapeGeometryMode.ENABLED.

Config config = session.getConfig();
// Streetscape Geometry requires the Geospatial API to be enabled.
config.setGeospatialMode(Config.GeospatialMode.ENABLED);
// Enable Streetscape Geometry.
config.setStreetscapeGeometryMode(Config.StreetscapeGeometryMode.ENABLED);
session.configure(config);

session.configure(
  session.config.apply {
    // Streetscape Geometry requires the Geospatial API to be enabled.
    geospatialMode = Config.GeospatialMode.ENABLED
    // Enable Streetscape Geometry.
    streetscapeGeometryMode = Config.StreetscapeGeometryMode.ENABLED
  }

StreetscapeGeometry contains information about a building:

• StreetscapeGeometry.getType()
  Identifies the StreetscapeGeometry as either terrain or a building.
• StreetscapeGeometry.getMesh()
  Obtain a polygon Mesh that corresponds to this terrain or building.
• StreetscapeGeometry.getMeshPose()
  Describes the origin of the geometry. All points in the Mesh should be transformed by StreetscapeGeometry.getMeshPose().
• StreetscapeGeometry.getQuality()
  Provides the quality of the mesh data. Levels of detail are described in the CityGML 2.0 standard.

StreetscapeGeometry.Quality.BUILDING_LOD_1 consists of building footprints extruded upwards to a flat top. Building heights may be inaccurate.

StreetscapeGeometry.Quality.BUILDING_LOD_2 will have higher fidelity geometry. Mesh walls and roofs will more closely match the building's shape. Smaller features like chimneys or roof vents may still poke outside of the mesh.

Mesh is a polygon mesh representing a surface reconstruction of the Streetscape Geometry. Each Mesh includes a vertex buffer and index buffer:

• Mesh.getVertexListSize()
  Retrieves the number of vertices in this mesh.
• Mesh.getVertexList()
  Obtain the concatenated positions of mesh vertices, in coordinates relative to StreetscapeGeometry.getMeshPose().
• Mesh.getIndexListSize()
  Retrieves the number of indices in this mesh.
• Mesh.getIndexList()
  Obtain the indexes of vertices that make up a face.

There are two ways to attach AR content to Streetscape Geometry:

• Enable Geospatial Depth and use a Depth hit-test. This is the recommended and easier method.
• Use Trackable.createAnchor() to create an anchor at a given pose attached to a StreetscapeGeometry. This anchor will inherit its tracking state from the parent StreetscapeGeometry.

Frame.hitTest() can be used to hit-test against Streetscape Geometry. If intersections are found, HitResult contains pose information about the hit location as well as a reference to the StreetscapeGeometry which was hit. This Streetscape Geometry can be passed to Trackable.createAnchor() to create an anchor attached to it.

for (HitResult hit : frame.hitTest(singleTapEvent)) {
  if (hit.getTrackable() instanceof StreetscapeGeometry) {
    Pose hitPose = hit.getHitPose();
    hit.getTrackable().createAnchor(hitPose);
  }
}

for (hit in frame.hitTest(singleTapEvent)) {
  if (hit.trackable is StreetscapeGeometry) {
    val hitPose = hit.hitPose
    hit.trackable.createAnchor(hitPose)
  }
}

Geospatial Depth combines Streetscape Geometry with local sensor input to enhance depth data. When Geospatial Depth is enabled, the output depth and raw depth images are modified to include rasterized Streetscape Geometry in addition to locally observed depth. This may improve the accuracy of poses using Depth.
