Obstacle Information for Robot Path Planning in Real Environment Maps

A method for transforming non-standard real environment photos into standardized grid maps for robot navigation. The dataset, authored by Feng Li and last updated on 2026-05-07, is shared under a CC-BY-4.0 license and is stored in an XLS file format. It is a small dataset at 5.5 KB, focusing on obstacle representation with safety margins.

Use Cases

• Training or testing robot path planning algorithms based on standardized grid map representations.
• Developing methods for converting real-world environment images into navigable models based on the described transformation process.
• Simulating robot navigation with safety margins based on the described obstacle expansion technique.
• Benchmarking the efficiency of different grid map generation techniques for robotics applications.

Strengths

• Dataset is openly shared under a permissive CC-BY-4.0 license.
• Specific file size of 5.5 KB indicates a focused, manageable scope.
• Methodology for obstacle expansion to add safety distance is explicitly described.

Limitations

• Row count and column definitions are unknown, limiting assessment of data structure and scale.
• The dataset is very small (5.5 KB), suggesting it may be a proof-of-concept or sample rather than a large-scale resource.
• Column-level documentation is absent; field semantics must be inferred after download.
