PreScan V7.4

  • New Bounding Rectangle Sensor:
  • run multiple bounding rectangle sensors in parallel which will result in decreased run time.
  • The quality of the sensor has been improved where possible and the new bounding rectangle sensor detects each sensor detectable object.
  • The new Bounding Rectangle Sensor focuses on its primary output: bounding rectangles. Therefore a convenience block (part of the 'Useful Blocks' in the Simulink library) is needed when the rectangles are needed in combination with the images from the Camera Sensor because the Bounding Rectangle Sensor does not output Camera Sensor-like images anymore.
  • Camera Sensor:
  • PreScan version 7.4.0 can run multiple camera sensors are run in parallel and will therefore result in decreased run time.
  • Also,  it is now possible to disable the viewer output while still sending output images to Simulink resulting in reduced simulation time.
  • Updated IBEO plugin:
  • The new IBEO plugin is now also capable of supporting ego vehicle lane changes since ego lane is detected and used for road generation. In previous versions of the plug-in ego vehicle lane changes would result in shifted road locations.
  • Also, the measured road width (at the beginning of the recording) is used throughout the simulated road.
  • General enhancements:
  • The remote viewer is now capable of running in a borderless window and can be positioned.  This allows rear-view mirror images to be modeled in driving simulator applications.

Instead of a hard cut-off distance, a more realistic set of statistical models is used.


  • Updated radar sensor model

PreScan V7.1.1

  • New physics based camera sensor model

The traditional RGB-based camera implementation created images limited to the visual spectrum. In contrast, the new PreScan spectral HDR camera model allows for high color depth, broad spectrum and physically correct image generation. The model simulates light in the 320-1500nm spectral range which traverses through the various media and lenses before the sensor model produces the final image signal. Other important features of this new spectral HDR camera model are a depth resolution of 20 bit per waveband as well as an increased dynamic range. 


  • Line Placed Marker

Lane Markers can now be added to Paths or to Road Segments. This makes it possible to add a repeated patterns of markers to a scenario at any location.

The scenarios can then be used like any PreScan scenario, for example to study the effects of using an Advanced Driver Assistance System (ADAS) in such a scenario. For more information please see the documentation of the plugin.


  • LaneMarkerSensor

The LaneMarkerSensor has been improved with regard to performance. The performance of multiple LaneMarkerSensors in one experiment has been improved significantly. The slices of the LaneMarkerSensor are configurable.

PreScan V7.0

  • Intelligent Traffic Module (licensed separately)

The Intelligent Traffic Module (ITM) is a plug-in capable of generating traffic on a road network without the need to manually create paths and logic to keep traffic flowing. ITM controlled vehicles will find the routes over a network to get them from point A to point B.  Host vehicle algorithms can thus be subjected to a wide variety of traffic situations.

  • Remote Viewer

The Remote Viewer plug-in contains functionality to run viewer windows on different (networked) machines.

Faded lane markers

  • Lens map distortions

Different types of (fisheye) lenses and non-perfect lenses can be modeled with lens look up maps. With this feature end-users are able to model their own specific kind of lens, including any distortion and/or imperfections. The fisheye lens camera effect now has an option to save and load the lens map to / from an external file.

  • Lens overlay

Lens overlay is a related feature to lens maps and involve a post-processing step where a configurable bitmap is drawn over the rendered view. Hence dirt and other artifacts can be mimicked. Another use-case is to use the overlay to add text or warning signals over the rendered view. The overlay can be switched on/off from Simulink, supplying the user with the appropriate feedback when required.

  • Coupling with dSPACE ASM vehicle models
    The dSPACE/ASM interface makes it possible to include detailed vehicle dynamics models from ASM vehicle models in the PreScan simulation.The interface has been extended to support driving the ASM vehicle model on complex 3D road networks from PreScan (eliminating the need to model the same roads in ASM).

PreScan V6.0

  • Fish eye camera
    A new camera sensor for modeling cameras with an ultra-wide angle lens (<360°) is now available. FOV, sensor size and image diameters can be specified.
  • Camera model updates
    - Barrel & pincushion distortion
    - Gaussian blur
    - Camera effects can be saved and re-used in different experiments.
    - Different cameras can have different effects (HDR, distortions, blur, vignetting, etc).
  • CAD import for IGES, STEP and 3DXML formats
    The importer of user-defined objects and actors is now able to read CAD formats (STEP, IGES and 3DXML) in addition to Collada formats.
  • Flexible road segment
    A new flexible road segment type enables the user to define a road with any number of definition points. It allows to easily create long stretches of road with many curves and bends.xle.
  • Standard scenario sets for 
    - AEBS ADAC performance tests
    - ACC ISO 15622:2002, ISO 22178:2009 and ISO/NP 22179
    - LDW NHTSA and ISO confirmation tests
  • Other enhancements
    - 3D vehicle dynamics for all database vehicles
    - Haptic feedback for steering console
    - Area color picker
    - Lane marker settings per lane line

PreScan V5.4

  • Light reflections
    Light reflections from vehicle lights or other active light sources on wet roads, vehicle surfaces (metallic paint) and reflective road objects.
  • Reflective road objects
    - Cat eyes
    - Botts' dotts
    - Guardrail reflectors
    - Reflective roadside poles & signs
  • Sensor visualization in 3D viewer
    Visualization of sensor beams is available for all sensor types (camera, radar, lidar, ultrasonic and V2x). Field of view, range and scan patterns can be visualized.
  • Vehicle dynamics for user-imported vehicle models
    PreScan vehicle dynamics properties can be assigned to vehicles that are imported via the user-defined library wizard. The wizard is extended to guide the user through the necessary steps.
  • New trailer type for truck modeling
    New trailer model with articulating shaft and front axle.
  • New AEBS and ACC demos in ADAS toolbox 
    - AEBS demonstrator for ADAC test scenarios
    - ACC with Stop & go for ISO test protocol
  • Support of dSPACE/ASM vehicle dynamics
    PreScan can now be used with dSPACE/ASM vehicle dynamics. The dSPACE/ASM interface makes it possible to include detailed vehicle dynamics from existing dSPACE/ASM models in the PreScan analysis.
  • Other enhancements
    - Occlusion option for bounding box ground-truth sensor
    - Smooth jerk option in speed profile editor
    - Support of Simulink acceleration mode
    - Sidewalks for all road segments
    - Automated import of road signs from OpenStreetMap database
