# Single Frame Localization

Single Frame Localization scene is a fundamental demonstration of how the platform performs localization within a mapped environment. This scene provides developers with a clear visualization of the SDK's core components. It showcases essential SDK prefabs, including the MultiSet SDK Manager which handles authentication, and the Map Localization Manager which manages the localization process.

This scene uses a single camera frame to localize against the map, ideal for situations where you want a quick response from localization API (\~3 seconds) and don't require precise accuracy

\
[**SingleFrameLocalization**](/multiset/unity-sdk/api-reference/singleframelocalizationmanager.md) is the primary script for the scene. Check out the details API Reference [here](/multiset/unity-sdk/api-reference/singleframelocalizationmanager.md).\
\
**Auto Localize**: Automatic start localization at the start of the AR session

**Relocalization**: Trigger Localization request when AR session tracking is lost/limited; also trigger localization when the app comes from background.

**Confidence Check:** Enable this option to add a filter on localization response, higher confidence value will result in better accuracy but may reduce the number of successful localization attempts.

**Confidence Threshold**: if Confidence Check if enabled this.\ <br>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://multiset.gitbook.io/multiset/unity-sdk/sample-scenes/single-frame-localization.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
