Lidar SLAM in long narrow corridors – deceivingly challenging

Long narrow corridors in office buildings and industrial facilities are quite common environments for robotics and mapping applications. However, they are one of the more challenging environments for Lidar SLAM due to repetitive structural appearances and limited GNSS signals (You can learn how 3D Lidar SLAM works in this blog post). This time, we are showcasing Kudan Lidar SLAM (KdLidar) taking on this challenging environment with ease in this challenging environment using a very simple setup.

Kudan Lidar SLAM works robustly in these challenging but common environments without any external sensors

This scan was done only with an Ouster lidar (OS1-32) using its built-in IMU as a handheld scanner shown in the picture below.

As you may know, Kudan Lidar SLAM will detect and perform loop closure to optimize the point cloud map, and it indeed detected some loops during this scan but the effects are barely noticeable due to the very limited drift generated during the scan. This is a good indicator that Kudan Lidar SLAM is managing this challenging environment with ease.

This type of environment is challenging yet quite common across various applications.

  • Mapping and tracking for autonomous service robots operating within offices and commercial buildings
  • Mapping of office buildings for inspection, maintenance, and facilities management
  • Progress monitoring and documentation of construction worksites

Here are some of the details of the environment, and demo parameters.

  • Size of the area: Each corridor runs 50m – 60m length
  • Sensor: Ouster OS1-32 3D lidar: Only lidar, without further sensor fusion (however, we can utilize other sensors if needed)
  • The SLAM video is generated in real-time for progress monitoring and the high-density point cloud map is generated during post-processing

Please feel free to reach out to us if you operate within these types of environments or have other challenging environments that you need a solution for. See the difference commercial-grade SLAM can make as part of your solution. We are happy to solve the problems together.
