Point Cloud Editor

Demo Link

Check out the live demo of the Point Cloud Editor here.

Highlights

• Intuitive 3D Point Cloud Editing: Easily visualize and manipulate 3D point clouds with simple translation and rotation tools.
• Real-time Updates: Immediate feedback and visualization of changes made to the point cloud.
• Transformation Tracking: Accurate tracking and application of all transformations to ensure consistency between visualization and exported files.
• Support for Camera and Image Data: Import and visualize camera and image data alongside the point cloud for a comprehensive editing experience.
• Flexible Export Options: Export modified point cloud and image data in the correct format for seamless integration into your workflow.
• Cropping Editing Feature: Crop point cloud data to focus on specific areas of interest.

Limitations

• Performance: The current implementation might struggle with extremely large point cloud datasets due to browser memory constraints.
• Limited Editing Tools: The editor currently supports basic translation and rotation. More advanced editing features are planned for future updates.
• Browser Compatibility: While the tool works well in modern browsers, some older browsers may not support all features due to WebGL limitations.

Future Work

• Enhanced Performance: Implementing optimizations to handle larger datasets efficiently.
• Advanced Editing Tools: Adding more tools for detailed editing, such as point selection, deletion, and custom transformations.
• Extended File Format Support: Expanding support to include more point cloud and image data formats.
• Collaboration Features: Enabling real-time collaborative editing of point clouds.
• User Authentication: Adding user authentication and personalized settings for a more tailored experience.
• Scaling Function: Allow users to select two points and enter the real-world distance between them to scale the entire scene accurately.

Usage

Prerequisites

Ensure you have a modern web browser that supports WebGL (e.g., Chrome, Firefox, Edge).

Setup

1. Clone the repository:

   git clone https://github.com/JohannesKrueger/point-cloud-editor.git
   cd point-cloud-editor
   

2. Open index.html in your web browser.

Importing Data

1. Point Cloud Data: Click on the "Upload Point Cloud" button and select your point cloud file (points3D.txt).
2. Camera Data: Click on the "Upload Cameras" button and select your camera file (cameras.txt).
3. Image Data: Click on the "Upload Images" button and select your images file (images.txt).

Editing

1. Use the translation sliders (X, Y, Z) to move the point cloud.
2. Use the rotation sliders (X, Y, Z) to rotate the point cloud.
3. Toggle erase mode to remove unwanted points by clicking on them.
4. Use the sphere radius slider to crop the point cloud to a specific region.

Exporting

1. Click on the "Download Points" button to export the modified point cloud data (modifiedPoints3D.txt).
2. If images were imported, a modified images file (modifiedImages.txt) will also be prepared for download.

COLMAP Installation and Conversion

Ensure COLMAP is installed and added to your environment variables PATH

Windows

colmap model_converter --input_path /path/to/input_model_folder --output_path /path/to/output_model_folder --output_type TXT
