From raw LiDAR scan to paintable walls in seconds — onsite

🎨🤖 #PACO (Les Companions‘ autonomous painting robot) cuts painting time by easily getting instructions, from the technician onsite.

The process looks simple:
1️⃣ Scan ⇒ 2️⃣ Decide ⇒ 3️⃣ Let Paco Paint

But lots happens under the hood to make it “simple” by extracting:
🧱 consistent wall surfaces
📐 clean geometric boundaries
🪟 window and door openings
🚫 exclusion zones (holes, obstacles, protected areas)
📏 stable, bounded entities usable for planning

This requires:
📍 LiDAR-based SLAM for coherent spatial reference
🧩 fast & robust planar segmentation under real-site noise
🔗 plane merging and topology reasoning
✂️ constraint-aware boundary extraction

Today:
🏗️ 8 real deployments
🎨 15,000+ m² painted autonomously
🏆 France2030 Automated Machine award

Turning raw 3D points into geometry a robot can act on — and watching it perform on real walls — is deeply satisfying.

Raw 3D data in. Real-world action out. That’s Perception4D.

Showcasing Perception4D’s Expertise in Dynamic Robot Localization

We’re proud to highlight Manon Cortial-Picard ’s upcoming presentation at the “Localization and Navigation for Robotics” webinar, organized by Comité Robotique France 2030 .

Her talk on “Localization in Dynamic Open Environments” will demonstrate Perception4D’s cutting-edge work in large-scale multi-modal mapping (LiDAR, OSM, and more), real-time detection dynamic obstacles and evolving environments.

She will also discuss methodologies for long-term map maintenance, an often over-looked but critical step for safe autonomous robots in logistics, agriculture, and urban mobility.

This reflects our commitment to pushing the boundaries of robust, real-world robotics—where precision meets adaptability.

A digital twin is good. Dynamic and real-time are better



On April 1st &2nd, we will be in BIM World Paris in Paris, on a stand shared with Oslandia.
Perception4D adds to 3D the 4th dimension, time:
👉 A “live” digital twin, which can be analysed and activated in real time.

We develop 3D + time perception technologies capable of feeding Live Digital Twins from sensors and field data.
Concrete applications:
🏗 Dynamic construction sites
⚓ Port and maritime infrastructure
🏭 Dynamic industrial sites
✈️ Airport Operations

Where many digital twins remain static models, we provide real-time analysis.

If you work on Digital Twin, BIM, geospatial or sensor topics, come and discuss them at booth D96.
Where do you see the first really operational uses of the Live Digital Twin today?

 Project example: Real-Time Slope Detection for Safer Farming with 3D LiDAR

Manon Cortial

In one of our latest projects, we were thrilled to work with INRAE Clermont-Auvergne-Rhone-Alpes on a critical initiative: detecting dangerous slope angles in real-time along a tractor’s future trajectory using onboard LiDAR. The goal? Prevent rollovers on steep terrain by giving the tractor’s control system early warnings about hazardous inclines.

 Why it’s important: Tractor rollovers are a major safety risk in agriculture. By anticipating slope changes ahead of the vehicle, we can help operators and automated systems avoid dangerous situations—improving both safety and operational efficiency.

 How we made it happen:

  • LiDAR + Point Cloud Analysis: We started by helping select the right LiDAR and optimize its positioning on the vehicle. Then, we processed dense 3D point clouds and IMU data to map the terrain and calculate surface normals, identifying slope angles in real time.
  • ROS2 pipeline and CAN integration: take advantage of state of the art real time technologies and ensure seamless communication with the tractor’s control unit.
  • Rapid Iteration: Thanks to close collaboration with INRAE, we quickly refined the solution to match exactly their needs and specifications.

See it in action in the video below: The tractor’s projected trajectories, the LiDAR point clouds transformed back in the environment’s frame and the slope normals colored by potential rollover risks—all in real time!

This project showcases how Perception4D’s expertise in 3D and 4D perception (3D + time) can elevate your projects in autonomous vehicles, mobile robotics, or any industrial applications using 3D sensors, (LiDAR, RGBD cameras, etc.).

Working on something similar? Let’s talk! We’d love to explore how we can collaborate to turn your 3D data into actionable solutions.

Testing KISS-SLAM

At Perception4D, staying at the forefront of 3D LiDAR expertise means keeping a close eye on the latest research in the field

Just two days ago, the team at #StachnissLab introduced KISS-SLAM, their latest #SLAM algorithm, claiming it requires no parameter tuning.

We had just acquired a new 5km urban dataset, featuring narrow streets and steep slopes—the perfect test for KISS-SLAM.

The results? Outstanding! The algorithm successfully detected all necessary loop closures and produced a clean, accurate trajectory. Impressive work from the team! 👏

🚀 Need expert guidance or custom development for your #3D #LiDAR project? At Perception4D, we provide tailor-made solutions for SLAM, object detection, and 3D point cloud visualization & simulation.

Point Cloud Segmentation

🚀 A glimpse into a building block of a bigger project: Lidar point cloud segmentation, with only 3D points a Ouster OS1-128 Lidar.

🚗That’s the daily task of Autonomous Vehicles, and Perception4D applies to many other usages

🤖 Benchmarking and Retraining Deep Learning networks on inhouse data, from old-ish RandLanet PointPillars to KPConv and SuperPoint Transformer

💻 The direct usage goes from cleaning the scanned point cloud to computing road surface or cable length. And that’s a building brick for other projects.

🤝A huge thanks to Youssef OUCHOUID who work on this during his end of study internship supervised by Manon Cortial-Picard & Bastien Jacquet

3D Object Detection and Tracking

🚀 Excited to share Perception4D improvements in 3D object detection and tracking, thanks to close collaboration with MasterMind, LLC which has very nice Lidar scanning use cases, with 2x Ouster OS1-128 and a whooping 72 MP Ladybug6 spherical camera (from FLIR Systems, not used here).

🤖 Leveraging Mastermind’s data and hardware expertise with our advanced algorithms, we’re pushing the boundaries in accuracy and efficiency for real-world applications like autonomous vehicles and urban planning.

💻 The usage goes from cleaning the scanned point cloud to tracking and analyzing vehicle and people trajectories.

🙏 Thanks to Ouster Lidars, FLIR Systems, Trimble Applanix for their cutting-edge tech.
