# 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
