# Annotation Tool

3D Multi-Sensor Fusion Tool allows labelling of point clouds. The Tool Supports multiple features and interactions to support precise labelling. View [key features](/annotation-tool/key-features.md).

## Tool Support

* Datasets of Multiple sensors: Images, LiDAR, RaDar
* Sensor fusion: Labelling across sensors simultaneously
* Feature to Label Sequential & Non-Sequential Datasets
* Multiple [Drawing Tools](/annotation-tool/drawing-tools.md) to label points in 3D & 2D datasets:
  * [Cuboid](/annotation-tool/drawing-tools/cuboid.md), [Polygon 3D](/annotation-tool/drawing-tools/polygon-3d.md), [Brush Sphere](/annotation-tool/drawing-tools/brush-sphere.md), [3D Polyline](/annotation-tool/drawing-tools/polyline-3d.md), [Polygon 2D](/annotation-tool/drawing-tools/polygon-2d.md), [Rectangle](/annotation-tool/drawing-tools/rectangle.md), [Polyline 2D](/annotation-tool/drawing-tools/polyline-2d.md), Rectangle with Keypoint
* Aggregation of point clouds for identifying and marking Stationary Objects.
* Interpolation to mark Moving Objects

# Agent Instructions: 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:

```
GET https://docs.imerit-prod.io/annotation-tool.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
