We propose a Dataset for Open-Vocabulary Zero-Shot Object Navigation in Dynamic Environments (DOZE) that comprises ten high-fidelity 3D scenes with over 18k tasks, aiming to mimic complex, dynamic real-world scenarios. Specifically, DOZE scenes feature multiple moving humanoid obstacles, a wide array of open-vocabulary objects, diverse distinct-attribute objects, and valuable textual hints. Besides, different from existing datasets that only provide collision checking between the agent and static obstacles, we enhance DOZE by integrating capabilities for detecting collisions between the agent and moving obstacles.
You can download the dataset on 😴DOZE🐱
# Install openxlab

The scenes_static.tar.gz file is a static human obstacle scenes package, the scenes_dynamic_fixed.tar.gz file is a fixed trajectory moving human obstacle scenes package, the scenes_dynamic_random.tar.gz file is a random trajectory moving human obstacle scenes package. The episodes.tar.gz file is the data package for multiple navigation tasks.
# Dataset decompress
tar -xzvf episodes.tar.gz
mkdir scenes
cd scenes
tar -xzvf ../scenes_static.tar.gz
tar -xzvf ../scenes_dynamic_fixed.tar.gz
tar -xzvf ../scenes_dynamic_random.tar.gz
The final hierarchy should look as follows:

The episodes folder contains four navigation tasks: Appearance, Spacial, OV (Open-Vocabulary), and Hint. The static folder contains 10 3d scenes with static humanoid obstacles, the dynamic_fixed folder contains 10 3d scenes with fixed trajectories moving humanoid obstacles, and the dynamic_random folder contains 10 3d scenes with random trajectories moving humanoid obstacles. In these scene folders, DOZE_xxxxxx.x86_64 is the executable file.
Here is an example of the structure of a single episode in our data set.

}A DOZE_x.json file contains all the tasks in a DOZE_x scene. Key parameters include:
id: the index of the task.scene: the scene for this task.initial_horizon: the horizon of the agent's initial state. the horizon change's the camera's rotation. Values are clamped between [-30:30].initial_orientation: The initial rotation of the agent.initial_position: initial position of the agent.goal_object: target object.shortest_path: a dictionary containing the shortest paths from the starting point to the neighborhood of the target object.shortest_path_length: shortest path length from source to that target.
To set up the environment, follow these steps:
pip install -r requirements.txt
cd scripts
