Version: 3.5.0

Release Notes 3.4.x

Version 3.4.15​

Aug 26th, 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 3.4.14​

May 26th, 2025

LiDAR Connection​

  • CHANGED | Update Luminar Iris Driver

Platform​

  • NEW | Rosbag Topic Preview when selecting a rosbag for an algo node, the available topics will be suggested when adding a ros message.

Web-Frontend​

  • FIXED | Fixed Luminar Iris setup modal
  • FIXED | Fixed Algo Node setup modal

Version 3.4.13​

April 25th, 2025

LiDAR Connection​

  • NEW | Added RoboSense Airy LiDAR

Platform​

  • NEW | Added Playback feature allowing to pause frames and step forward/backwards using arrow keys `Preferences > Playback Debugger`

Algorithm​

  • NEW | (Internal) Opened several parameters in Cluster Merger, Classifier, and Tracker
  • NEW | LiDAR mirroring feature that allows duplicating LiDAR topics and allocating them to other Algo nodes to apply different sets of parameters to specific regions

Web Frontend​

  • FIXED | Fixed potential deadlock when receiving/sending logs to the web-frontend

Output​

  • FIXED | Fixed bounding box size for indoor preset. Previously, the ground margin was subtracted, making objects appear smaller than they actually are
  • NEW | Added Option to not publish validating, invalidating, drifting, and miscellaneous objects `General Parameters > Output > Publish Unreliable Objects`

Version 3.4.12​

April 1st, 2025

Platform​

  • CHANGED | Updated Opsys Altos driver following firmware change
  • CHANGED | Updated Livox HAP driver for lower resource consumption

Platform​

  • CHANGED | Updated locking feature to let the user navigate within the 3D viewer while SENSR locked

Version 3.4.9​

January 20th, 2025

Algorithm​

  • CHANGED | Improved multi-node merger for large datasets (10,000+ objects) to reduce CPU pressure

Platform​

  • FIXED | Fixed bug where the master node was crashing when importing an obj file that was pointing at a mtl file without the mtl file being provided
  • CHANGED| Product name changed from SENSR to SR Perception

Version 3.4.8​

Platform​

  • FIXED | Fixed edge-case crash in starting rosbag record
  • CHANGED| Roscore docker image updated to reduce security vulnerabilities

Version 3.4.7​

August 8th, 2024

LiDAR Connection​

  • CHANGED | Updated OT128 driver for lower resource consumption.
  • CHANGED | Updated Ouster driver based on latest release on Ouster github repository.

Algorithm​

  • NEW | Added a new 3D object detector for reducing merging between pedestrians and vehicles - This feature consumes a significant amount of computing resource.
  • CHANGED | Improved the Master node merging algorithm to increase accuracy of object handover between Algo nodes.
  • CHANGED | Updated the noise object filter to remove unwanted ghost objects.

SR Launcher​

  • NEW | Replacement of TLS 1.0 and 1.1 with TLS 1.2.
  • NEW | Closure of unused ports 8880 and 8443.
  • CHANGED | Reverted changes from 3.3.0 to enable running SENSR on Virtual Machines - Note: Seoul Robotics does not test SENSR on virtual machines, if a difficulty is encountered, please contact support@seoulrobotics.org.
