The following sections present the new features, enhancements and changes for AVxcelerate Sensors 2025 R1 release.
This section describes the new features introduced in AVxcelerate Sensors Simulator 2025 R1 release.
You can now obtain information on the electromagnetic propagation of a radar with respect to the dielectric properties of materials in the scene, thanks to the simulation mode for propagation output. Available as a beta feature in the 2025 R1 release of AVxcelerate Sensors Simulator, you can now use the Sensor Modeler application or the Sensors REST API to create a radar model with a mode which produces propagation output. Simulate the electromagnetic propagation by adding the radar to a sensor configuration and setting the relevant radar simulation parameters.
For more details on the generated output, refer to Propagation Output Data in the AVxcelerate Sensors Simulator User's Guide.
In the 2025 R1 release, it is now possible to extend IP protection to your cameras and fisheye cameras. To maintain the confidentiality of your sensor component details, from the Sensor Modeler or Sensors REST API, you can now activate protection on the Imager section of a camera or fisheye camera. IP protection for camera sensors allows for:
a first layer of encryption for *.camerax files which prevents its data from being read without the use of AVxcelerate Sensors applications.
a second layer of encryption for the Imager section of a camera or fisheye camera model and its associated files thanks to a password protection feature in the Sensor Modeler and the Sensors REST API.
When Protection is activated on the Imager section of a camera or fisheye camera, only the Native Resolution parameters from this section can be viewed or modified.
This section describes the enhancements introduced in AVxcelerate Sensors Simulator 2025 R1 release.
In 2025 R1 the AVxcelerate Sensor Labs software has renewed its focus on the user experience. Find a much-improved version of the Sensor Modeler and Sensor Layout applications which not only benefit from an overhaul of the interface for a more visually appealing experience, but from new functionalities for a better navigation of your libraries. Among the enhancements you can find:
a Change theme button to switch between light mode and dark mode
a redesign of the sensor and sensor layout cards
the addition of a List View for your libraries
information regarding your sensor's status and the content of your sensor layouts
filters for refined searches
the ability to download or delete using multiple selection.
For more details, refer to the Sensor Modeler and Sensor Layout sections of the AVxcelerate Sensors Simulator User's Guide.
Some samples that demonstrate the use of corner reflectors to calibrate radar sensors are now delivered in the standalone and co-simulation libraries.
In the AVxcelerate Standalone Library, the sample is a python script located in the %AVXLIB_ROOT251%\Samples\CornerReflectors folder. For more details, refer to the README.md file.
In the AVxcelerate SCANeR Sensors Cosimulation library, three sample scenarios are provided in your SCANeRstudio_2021 folder in data\VRXPERIENCE_SENSORS_2025R1\scenario\CornerReflectorsScenarios. For more details on each scenario, refer to the scenario's description.
In the AVxcelerate CarMaker Sensors Cosimulation library, three sample TestRuns are provided in your CM_Projects folder in AVX_SENSORS\2025R1\DataPools\CM[version]\Data\TestRun\CornerReflectorsScenarios. For more details, refer to the README.txt file.
AVxcelerate Sensors Simulator is now also compatible with CarMaker version 13.0 and CarMaker HiL version 13.0. CarMaker version 10 is, however, no longer supported.
The CarMaker and CarMaker HiL versions supported by AVxcelerate Sensors Simulator 2025 R1 are 11.0, 11.1, 12.0, 12.0.1, 12.0.2, 13.0.
The AVxcelerate Asset preparation API v3 delivered in 2025 R1 allows you to import assets and tracks to the server thanks to new methods added to the Environment Preparation and Scene Tree Preparation services.
For more details on this new feature and about other changes introduced in this release, refer to the changelog provided in the API documentation.
The following improvements have been made to sensor simulation:
Simulation performance across all sensors has improved thanks to the optimization of data serialization resulting in the reduction of periodic slowdowns.
A black image is displayed when incompatible output formats are configured and Display is enabled in the camera simulation parameters.
It is now possible to define a delay for a sensor simulation using the start offset parameter. This parameter, which can be applied to any sensor type, can be used:
to optimize and better control the frequency and consistency of sensor data production. Refer to Update Frequency and Sensor Production Period in the AVxcelerate Sensors Simulator User's Guide to understand the impact of this parameter on data production.
to simulate a multi-radar configuration designed to reduce interference among radars. Set the start offset in the radar simulation parameters.
to simulate a High Dynamic Range (HDR) camera through a multi-camera configuration. Refer to the start offset parameter in the camera simulation parameters to understand how to use this parameter to simulate an HDR camera.
The new pedestrian_male_lidar_radar.asset file provided in the AVxcelerate Sensors Standalone Library is an animated pedestrian designed for LiDAR and radar simulations. The corresponding CarMaker object is provided in the CarMaker AVxcelerate Sensors Library for CarMaker.
Note: This file has been adapted from an Adobe Mixamo animated character (https://www.mixamo.com/). As a consequence, you must comply with the Adobe terms of use (Adobe General Terms of Use) when using these specific assets. In particular, you must not use those assets "to directly or indirectly create, train, test, or otherwise improve any machine learning algorithms or artificial intelligence system, including but not limited to any architectures, models, or weights" (extract from section 17. of Adobe terms of use).
This section describes the changes introduced in AVxcelerate Sensors 2025 R1 release.
To install AVxcelerate Sensors, as well as its related libraries, for SCANeR and for CarMaker, you should now use the Ansys Automated Installer available from the Current Release page of the Ansys Customer Portal.
Important notes
When you install AVxcelerate Sensors on a Linux OS workstation, you can now select the installation directory.
The default installation directory path for installing the product on Linux OS is now /usr/ansys_inc, which differs from the installation directory of previous versions (which was /ansys_inc/)
The set of files that were previously installed when selecting AVxcelerate Standalone Library are now installed along with the AVxcelerate Sensors product. You can still select the installation directory for this library, which is now named AVxcelerate Sensors Standalone Library during the installation.
Remote Direct Memory Access (RDMA) is now available in the 2025 R1 release of AVxcelerate Sensors Simulator as a beta feature using NI RDMA technology. Activated through the camera simulation parameters, the RDMA component allows for the transfer of camera and imager output to an RDMA receiver via the NI RDMA card. Previously released as an experimental feature, in the 2025 R1 release:
the Buffer Size parameter has been renamed Transfer Chunk Size
four additional parameters have been added to allow you to add pre-embedded and post-embedded data lines to the transferred data.
In the 2025 R1 release of AVxcelerate Sensors Simulator, the RDMA plug-in is not provided in the installer. If you wish to use RDMA to transfer your camera simulation data, you must request the RDMA archive and pre-requisite files.
AVxcelerate Sensors Simulator, AVxcelerate Sensor Labs (applications and REST APIs), as well as the unpacker executable no longer support the sensors created with a version prior to 2022 R2.
This section lists all the changes introduced in VSS API version 2025 R1 compared to version 2024 R2.
The start_offset field has been added to the SensorParameters message.
In the RemoteDirectMemoryAccess message:
the buffer_size field has been renamed transfer_chunk_size, but the index of this field has not changed.
the following field have been added:
post_embedded_data_line_count
post_embedded_data_line_payload_size
pre_embedded_data_line_count
pre_embedded_data_line_payload_size
