RecolorCloud is a tool designed to address color conflicts in point clouds, improving the photo-realistic quality of large point clouds. It allows users to delete or recolor outlier points and offers the ability to quickly recolor a point cloud with set semantic segmentation colors. While point cloud editors generally have features for cropping, recentering, registering, and segmenting point clouds, not all of them support recoloring. RecolorCloud aims to provide a convenient way of recoloring point clouds using semi-automated algorithms, user-controlled segmentation, and conversion between different point cloud formats. It supports large point clouds with over 100 million points and has been successfully applied to datasets like the Greek Park dataset and the Multisensor Indoor Mapping and Positioning Dataset. However, RecolorCloud relies on another tool called LabelCloud for generating bounding boxes and requires a Python back-end for running. Future work includes improving the user interface and incorporating point cloud selection. Overall, RecolorCloud is an open source tool that can handle large-scale point clouds and significantly improve their visual quality.

RecolorCloud is a tool designed to address color conflicts in point clouds, which are 3D representations of environments recorded by laser scanners. It aims to resolve issues caused by visual errors in current open source or proprietary tools, such as fake or incorrect colors due to environmental interference. RecolorCloud allows users to delete or recolor outlier points by specifying bounding box regions, significantly improving the photo-realistic quality of large point clouds. It also offers the ability to quickly recolor a point cloud with set semantic segmentation colors.
While point cloud editors generally have features for cropping, recentering, registering, and segmenting point clouds, not all of them support recoloring. Recoloring can be divided into direct recoloring and segmentation recoloring, with direct recoloring involving directly recoloring points to improve the quality of the point cloud, while segmentation recoloring involves recoloring the point cloud with high-contrast colors to create coarse segmentation categories. There are an equal number of tools that support direct and segmentation recoloring, but most of them are proprietary and close sourced. CloudCompare is the only open source tool that supports direct recoloring.
Current open source tools for point cloud editing have limitations when it comes to large-scale point cloud recoloring. Tools like Point Cloud Visualizer, Semantic Segmentation Editor, and CloudCompare are slow or crash when editing large point clouds. However, some open source tools like Semantic Segmentation Editor and 3D BAT provide support for creating bounds based on pre-existing clusters, allowing coarse selection of points in the point cloud.
RecolorCloud aims to provide a convenient way of recoloring point clouds using semi-automated algorithms, user-controlled segmentation, and conversion between different point cloud formats. It supports large point clouds with over 100 million points and offers features like recoloring and deleting points based on coloring criteria, file conversion, and fragmentation of point clouds based on bounds. RecolorCloud is open source, free of charge, and has been tested on various datasets, demonstrating its capabilities to perform recoloring and vastly improve the visual quality of point clouds.
RecolorCloud has been successfully applied to datasets like the Greek Park dataset and the Multisensor Indoor Mapping and Positioning Dataset. It has corrected errors and improved the quality of point clouds by removing excess white outlier points and recoloring remaining outlier points. The tool can also segment point clouds based on bounding boxes and convert point clouds between different formats.
However, RecolorCloud does have limitations. It relies on another tool called LabelCloud for generating bounding boxes, which limits its selection and editing capabilities. The user interface does not directly display the changes that will be applied to the point cloud before editing. Additionally, RecolorCloud requires a Python back-end for running, which may be a barrier for novice users. Future work includes making RecolorCloud a PyPi package for easier installation and distribution, removing the dependency on LabelCloud, improving the user interface, and incorporating point cloud selection.
In conclusion, RecolorCloud fills the gap for a tool that provides users with the ability to recolor and correct point clouds. It offers features for direct and semantic recoloring, outlier color correction, segmentation, and file conversion. RecolorCloud is an open source tool that can handle large-scale point clouds and significantly improve their visual quality.

RecolorCloud is a tool developed to address color conflicts in point clouds, which are 3D representations of environments recorded by laser scanners. These scanners can introduce visual errors such as fake or incorrect colors due to environmental interference. Current open source or proprietary tools have limited or no automated color correction capabilities. RecolorCloud aims to resolve these issues through automated color recoloring. It allows users to delete or recolor outlier points by specifying bounding box regions. This tool significantly improves the photo-realistic quality of large point clouds. It also offers the ability to quickly recolor a point cloud with set semantic segmentation colors.

RecolorCloud is open source and free of charge. It has been tested on various datasets and has demonstrated its capabilities to perform recoloring and vastly improve the visual quality of point clouds.
RecolorCloud has been applied to datasets like the Greek Park dataset, which contained noisy outlier colors in trees. By removing excess white outlier points and recoloring the remaining outlier points, RecolorCloud corrected the errors and improved the quality of the point cloud. RecolorCloud has also been used to semantically recolor point clouds, as demonstrated in the Greek Park dataset and the Multisensor Indoor Mapping and Positioning Dataset. It can segment point clouds based on bounding boxes and convert point clouds between different formats.
RecolorCloud has several limitations. It depends on another tool called LabelCloud for generating bounding boxes, which limits its selection and editing capabilities. The user interface does not directly display the changes that will be applied to the point cloud before editing. Additionally, RecolorCloud requires a Python back-end for running, which may be a barrier for novice users.
