RTAB vs Textxt

RTAB-Map (Real-Time Appearance-Based Mapping) is an Open Source LiDAR / RGB-D / Stereo Graph-Based SLAM (Simultaneous Localization and Mapping) approach based on an online incremental appearance-based loop closure detector. The loop closure detector uses a bag-of-words approach to determinate how likely a new image comes from a previous location or a new location. When a loop closure hypothesis is accepted, a new constraint is added to the map's graph, then a graph optimizer minimizes the errors in the map in real-time. An optional memory management approach can be used to limit the number of locations used for loop closure detection and graph optimization, so that real-time constraints on large-scale environnements are always respected. ARKit's visual inertial odometry (VIO) is used as the SLAM front-end for RTAB-Map (the SLAM back-end). * Note that unlike other scanning apps that optimize the map only after mapping, with RTAB-Map you get loop closure detection and map optimization online so you can have a live feedback to know when you have enough constraints in the map for good global optimization before stopping the scan. *** 3D reconstruction available only with LiDAR sensor. Features: * Online 3D scanning/mapping of the environment. * Online loop closure detection and map correction. * Save in DB format (RTAB-Map desktop and rtabmap_ros format). * Export in PLY, LAS or OBJ. * Multi-session mapping (save and continue later). * Use Apriltags to help finding loop closures in textureless environments. * Mixed AR/VR First-Person in visualization mode. * Raw ARKit data recording (up to 60 Hz!), useful to record long sessions without comprising battery life.

Start with a conversation. Keep building on it. Textxt brings messages, notes and next steps into one workspace. Use it for your own ideas, a shared project, a study group or the work your team does every day. GIVE EVERY SUBJECT A PLACE Organize a chat into topics so feedback, references and decisions stay together. Keep the project connected without mixing every discussion into one stream. WRITE MORE THAN A MESSAGE Create structured notes with Markdown: headings, lists, checklists, tables, code and formulas. Keep files and images beside the discussion, from a quick thought to a detailed project brief. KEEP THE NEXT STEP CLOSE Turn messages into tasks, assign owners and track subtasks. Set reminders to return to an important message when it is time to follow up. ASK AI ABOUT THE WORK Use AI Assistant with selected, permitted context. Ask for a summary, explore a question and check the linked sources. Review suggested actions before applying changes. AI responses can be inaccurate; check important information. SHARE WHAT YOU CHOOSE Share selected content with a link, or publish posts on your profile. Follow people and discover their ideas in Feed. Private conversations are not public unless you choose to share them. START SMALL A private note. A conversation with someone. A project with your team. Build the workspace you need as the work grows. Feature availability and usage limits can vary by platform. Check the app for current availability.
