U-Tube Manometer Dataset (2025–2026)

This dataset contains images of U-tube manometers and is designed for computer vision regression and classification tasks, focusing on reading and interpreting liquid column levels.

• Performance may vary under extreme lighting or occlusion conditions

Dataset Summary

The U-Tube Manometer Dataset consists of 20,000 images of U-tube manometers with visible water columns. The dataset is suitable for:

• Image Regression: estimating the numerical value of the water column height
• Image Classification: classifying images based on discrete column values or ranges

Images are organized in a folder structure where the label is encoded in the directory name, representing the measured water column value.

Data Structure

The dataset follows a standard split structure:

dataset/
├── train/
│   ├── 10.2/
│   │   ├── image23.png
│   │   └── ...
│   ├── 10.4/
│   └── ...
├── validation/
│   ├── 9.8/
│   └── ...
└── test/
    ├── 10.0/
    └── ...

• Each subfolder name corresponds to the label value (e.g., water column height in centimeters).
• Images inside the folder share the same height value.

Image Characteristics

• RGB images
• Varying lighting conditions
• Varying working fluids (water, oil, water–ink mixtures)
• Single U-tube manometer per image
• Visible liquid columns and scale markings
