## Properties

| Name | Type | Summary |
| --- | --- | --- |
| var anchorDistanceGateMeters | Float | Distance gate in meters for anchor candidate filtering when geo-corrected.Nodes farther than this distance from the device are skipped during anchor localization.When only GPS is available (no geo-correction), the effective gate is 2x this value.Use 0 to apply the default value (100 meters geo-corrected, 200 meters GPS-only).Use -1 to disable the distance check entirely. |
| var assetTargetingEnterMarginMeters | Float | How far outside a VPS asset's geographic bounds the device can be and still startlocalizing against that asset, in meters.Covers ordinary GPS error, so a device standing just outside an asset still picks itup. An asset the server published no bounds for is always a candidate.Use 0 to apply the default value (25 meters). Use a negative value for no margin,judging the bounds exactly. |
| var assetTargetingExitMarginMeters | Float | How far outside its bounds an asset already being localized against is kept, in meters.Larger than `assetTargetingEnterMarginMeters` on purpose: the gap between the two iswhat stops a device sitting on the boundary between two assets swapping between them onevery position update. A value below the enter margin is raised to it.Use 0 to apply the default value (50 meters). Use a negative value for no margin. |
| var blurDetectionEnabled | Bool | If true, enable the image blur check on the cloud localization path.Advisory only: a frame whose sharpness score is below `minSharpnessScore` producesa `.frameFlagged` localization request record (error `.imageTooBlurry`) so the appcan warn the user, but is still sent for localization, never rejected.Default false (disabled). |
| var continuousVpsRequestsPerSecond | Float | Number of VPS localization requests per second to send the server whilesuccessfully localized on a VPS map. |
| var deviceMapLocalizationEnabled | Bool | Device maps are created by the on-device mapping feature. They do not providea georeference. |
| var deviceMapLocalizationFramerate | Int32 | Number of times per second to attempt localization on available device maps. |
| var geolocationSmoothingEnabled | Bool | If true, geolocation smoothing is enabled. |
| var initialVpsRequestsPerSecond | Float | Number of VPS localiziation requests per second to send the server prior to firstsuccessful localization on a VPS map. |
| var maxRequestsInTransitPerTarget | UInt32 | Maximum number of concurrent localization requests per target.Limits how many in-flight cloud localization requests can be active for a single targetsimultaneously. Use 0 to apply the default value (2). |
| var minSharpnessScore | Float | Sharpness threshold below which a frame is flagged as too blurry.Higher scores mean sharper images. The default 0.0 flags nothing, since the score isalways non-negative. Only used when `blurDetectionEnabled` is true. |
| var temporalFusionEnabled | Bool | If true, successive VPS localizations are temporally fused.Fusion smooths the localization stream, at the cost of latency reacting to a genuinepose change. Enabled by default; turn it off to see raw per-localization output. |
| var universalLocalizationEnabled | Bool | If true, universal localization is enabled.Universal localization provides geographic positioning that works anywherewithout requiring pre-scanning. |
| var universalLocalizationRequestsPerSecond | Float | Number of requests per second to send the cloud for universal localization. |
| var universalLocalizationRequestTimeoutMs | Int32 | Timeout in milliseconds for universal localization requests.Responses in uncached areas may take 60+ seconds; subsequent requests are typicallyunder 1 second. Use 0 to apply the default value (90000 ms). |
| var vpsDebuggerEnabled | Bool | If true, VPS debugger logging is enabled for this session. |
| var vpsDebuggerSavingFrameImageEnabled | Bool | If true, attach a small JPEG thumbnail of localize frames to VPS debuggernetwork request events. Requires `vpsDebuggerEnabled`. |
| var vpsMapLocalizationEnabled | Bool | If true, VPS map localization is enabled.VPS maps only exist in pre-scanned areas. Your device must be localized ona VPS map in order for VPS anchors to be placed with high accuracy. |
