CrossPoint-378K Dataset

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

{
  "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
