# **Dataset Description**

This dataset was created to support Article X and is available on [Roboflow](https://universe.roboflow.com/visiongauge/utm_dataset-ooorv) and [Hugging Face](https://huggingface.co/datasets/claytonsds/UTM_Dataset).

It consists of images of **U-tube manometers** constructed using a **transparent PVC water level hose (5/16" × 1 mm)** and **flexible measuring tape** with a length of **150 cm (60 inches)**. The manometric fluids represented in the dataset include **water, oil, and dyed water**. The dataset is intended for testing ML models for reading liquid column levels.

The dataset includes  **904 unique original images**. All annotations were performed using the RoboFlow Annotate Tool, with label precision within ± 0.1 cm.


# **Dataset Split**
![dataset distribution](https://github.com/ClaytonSdS/VisionGauge/blob/main/steps/utm_testing_dataset_dist.png?raw=true)

* **Test set:** 904 images

# Data Structure

The dataset follows a standard split structure:
```
dataset/
├── test/
│    ├── 10.0/
│    └── ...
└── dataset_mapping.csv
```

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