Lidar .bin dataset Visualization

This Python script visualizes LiDAR point cloud data stored in binary (.bin) format. It provides both 3D and 2D projections for better analysis.

Features

• 3D Visualization: Displays LiDAR point cloud in a 3D scatter plot.

• 2D Projections:

  • Top-down view (XY plane)

  • Side view from X-axis (XZ plane)

  • Front view from Y-axis (YZ plane)

• Color mapping based on Z-values or intensity (if available).

Requisites

$ pip install -r requirements.txt

Usage

Run the script with the .bin file and specify the desired visualization type:

$ python3 script.py {bin_file} {axis}

Arguments:

• {bin_file}: Path to the binary LiDAR point cloud file.

• {axis}: Choose visualization type:

  • 3d → 3D visualization

    • xy → Top-down view

    • xz → Side view from X-axis

    • yz → Front view from Y-axis

Example Commands:

$ python3 script.py samles/000002.bin 3d  # 3D visualization
$ python3 script.py samles/000002.bin xy  # Top-down view
$ python3 script.py samles/000002.bin xz  # Side view
$ python3 script.py samles/000002.bin yz  # Front view

Notes

The script assumes the binary file contains float values in the order: x, y, z, intensity.

If intensity is not available, Z-values are used for coloring.

Ensure the .bin file follows the correct format before visualization.
