Detection

Object

Detections are the lowest level unit of computer vision primitive within Worlds. A detection represents a single frame of a recognized object, which then has additional data associated with it, including its position, track, and interactions with zones and geofences.

Fields

Field	Type	Description
`id`	`ID!`	The unique identifier for the detection.
`track`	`Track!`	The track that is associated with the detection.
`timestamp`	`DateTimeOffset!`	The time at which the detection occurred.
`frame`	`Frame`	Information about the video frame in which this detection was captured
`polygon`	`GeoJSONPolygon`	A GeoJSON polygon that represents the spatial bounds of the detection.
`position`	`GeoJSONPoint`	A GeoJSON point that represents the location of the detection in the world. This value may be `null` if the camera that captured the detection hasn’t been calibrated. It may also be `null` if the location cannot be calculated (i.e the detected object is in the sky).
`zones`	`[Zone!]!`	A list of Zones with which the detection intersects.
`geofences`	`[Geofence!]!`	A list of Geofences with which the detection intersects.
`metadata`	`JSON`	Arbitrary metadata associated with the detection.
`createdAt`	`DateTimeOffset`	Timestamp that the detection was created. May be delayed from the `timestamp` due to post-processing video feeds or other latency.
`updatedAt`	`DateTimeOffset`	Timestamp that the detection was most recently updated.
`direction`	`Float`	The direction in which the detection is moving, represented in degrees.
`geofenceIds` Deprecated	`[ID!]!`	A list of geofence unique identifiers with which the detection intersects. Deprecated: `geofenceIds` is deprecated. Use `geofences.id` instead
`zoneIds` Deprecated	`[ID!]!`	A list of zone unique identifiers with which the detection intersects. Deprecated: `zoneIds` is deprecated. Use `zones.id` instead
`globalTrackId` Deprecated	`String`	The global track id that governs the detection, if any. Deprecated: `globalTrackId` is deprecated. Use `track.id` instead
`deviceId` Deprecated	`ID`	The unique identifier of the device where the detection occurred. Deprecated: `deviceId` is deprecated. Use `track.dataSourceId.id` instead
`tag` Deprecated	`String!`	The class label of the detected object, i.e person, car, truck, etc. Deprecated: `tag` is deprecated. Use `track.tag` instead
