Version 3.5.2​

Aug 27th, 2025

Platform​

  • CHANGED | Optimized the merger algorithm to improve performance, previously some significant delay could be experienced in setups with multiple algo nodes larger than 500m x 500m.

Version 3.5.1​

August 12th, 2025

Platform​

  • CHANGED | Added environment variable `SENSR_ALGO_NODE_COUNT` into single machine installer to select the maximum number of algo nodes that will be created by the instance (Default: 3)

Algorithm​

  • CHANGED | Minimum cell size for ground profiling reduced to 0.05 meters

LiDAR Connection​

  • CHANGED | Updated Ouster driver that led LiDARs to appear with a 180 degrees-shifted yaw compared to 3.4.x

Version 3.5.0​

July 21st, 2025

Platform​

  • NEW | Base operating system upgraded to Ubuntu 22, with SR Launcher support extended to Ubuntu 24.
  • NEW | Full migration to ROS 2, replacing the previous ROS 1 integration.
  • NEW | Added support for NVIDIA Jetpack 6.
  • CHANGED | Docker image sizes significantly reduced and loading parallelized for faster startup times
  • CHANGED | The single-machine installer now supports up to 3 algo nodes to allow zone-based parameters.
  • FIXED | The ROS Subscriber Interface now automatically restarts if it stops receiving data.
  • FIXED | Corrected a bug related to the recovery of an algo node after an update.
  • CHANGED | The system now automatically selects a default preset based on hardware: 'Outdoor GPU' if a GPU is available, and 'Indoor' otherwise.

Algorithm​

  • CHANGED | The Clusterer and Event Zone logic has been optimized for performance.
  • NEW | Added an option to refine deep learning bounding boxes for improved accuracy.
  • FIXED | Fixed a crash caused by a missing zone name in background removal configurations.

LiDAR Connection​

  • NEW | Added support for the Hesai JT128 LiDAR.
  • NEW | Added support for the Hesai Aeva Atlas LiDAR.

  • REMOVED | Removed LiDAR drivers for Aeye, Baraja, Blickfeld, Cepton, Leishen, Livox (Mid-40, Mid-70, Tele-15, Horizon, Avia), and Luminar (Hydra).

Visualization​

  • NEW | Each object's point cloud can now be visualized in a distinct color for easier identification.
  • CHANGED | The native GUI now displays object trails by default to better track movement.

Web-Frontend​

  • FIXED | Resolved an issue that prevented adding or editing LiDARs.
  • FIXED | Corrected a bug where configuration changes were not applied due to a type mismatch.
  • FIXED | Fixed an issue that occurred when creating a new algorithm node.

Removed Features​
