## Overview

CrossPoint-378K is a large-scale dataset for cross-view point correspondence. This dataset contains 378K training samples designed to enhance vision-language models' capabilities in cross-view point correspondences.

## Dataset Structure

The dataset contains the following file structure:

```
CrossPoint-378K/
├── CrossPoint-378K.json          # Main data file (ShareGPT format)
├── image/                         # Original images directory
│   └── [scene_id]/               # Scene ID directory
│       └── [images]              # Scene images
└── visual_image/                  # Annotated images directory
    └── [scene_id]/               # Scene ID directory
        └── [images]              # Annotated images with visual markers
```

## Data Format

The dataset follows the **ShareGPT format** with the following structure:

### JSON Format Example

```json
{
  "type": "single_spatial_understanding",
  "images": [
    "CrossPoint-378K/image/00a231a370/DSC05031.JPG"
  ],
  "messages": [
    {
      "content": "<image>\nWhat does the point at [56, 323] refer to?",
      "role": "user"
    },
    {
      "content": "It corresponds to the white window handle in the image.",
      "role": "assistant"
    }
  ]
}
```

### Field Descriptions

- **type**: Task type (e.g., `single_spatial_understanding`, `cross_correspondence`)
- **images**: List of image paths relative to the dataset root
- **messages**: Conversation in ShareGPT format
  - **role**: Either `user` or `assistant`
  - **content**: Message content, where `<image>` tokens indicate image positions
