| | # 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 |
