iPhone360 Dataset

iPhone360 is a benchmark dataset for 360° reconstruction of dynamic objects from monocular video, introduced in the paper:

4DGS360: 360° Gaussian Reconstruction of Dynamic Objects from a Single Video Jae Won Jang, Yeonjin Chang, Wonsik Shin, Juhwan Cho, Nojun Kwak Project Page · arXiv

Dataset Description

iPhone360 features real-world dynamic scenes captured with an iPhone, where test cameras are positioned at significantly different angles from training views. This enables evaluation of 360° reconstruction capabilities that existing datasets cannot provide.

Scenes

Scene	Description
block2	Dynamic object scene
goat	Dynamic object scene
jacket	Dynamic object scene
jelly	Dynamic object scene
pull-up	Dynamic object scene
walk-around	Dynamic object scene

Data Structure

Each scene contains:

• rgb/ — RGB frames

• masks/ — Object masks
• camera/ — Camera parameters
• splits/ — Train/test split definitions
• points.npy — Initial point cloud
• dataset.json / scene.json / metadata.json — Scene metadata
