Stereo Fish Dataset for BézierFusion: 3D Curve Estimation in Aquaculture

This dataset contains binocular stereo images and annotations for underwater fish detection and 3D body length measurement, supporting the research paper "Bézierfusion: A Unified Fish Detection and Measurement Paradigm".

Dataset Overview: The dataset consists of two distinct subsets covering different aquaculture scenarios:

Dataset 1 (Indoor Environment): Collected from an indoor grouper (Plectropomus leopardus) farm featuring a stable blue tank background.

Dataset 2 (Outdoor Environment): Collected from outdoor ponds, featuring complex challenges like weak textures and suspended particles.

Note on Data Completeness: This repository contains a representative subset of the full dataset. It includes the complete Test Set and a sample of the Training Set. This subset shares the exact same directory structure and annotation format as the full dataset, allowing researchers to run the provided code and reproduce the evaluation metrics reported in the paper.
