  • Collision Detection:
  • The collision detection functionality has been optimised in order to run at higher frame rates. This has been accomplished by putting the functionality in a separate process and by optimising the collision detection strategy.​
  • Depth Camera Sensor:
  • The depth camera sensor is re-implemented to profit from the multi-processor capabilities of PreScan. Multiple depth camera sensors are processed in parallel which results in a higher overall performance.
  • Fisheye Camera Sensor:

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.

  • Traffic sign pole and plate dimensions
  • Traffic sign imperfection parameters
  • Explicit sun position and intensity

This plugin enhances the algorithm for determining whether a transmitted messages are successfully received by a receiver. Instead of a hard cut-off distance, a more realistic set of statistical models is used.

 

  • Updated radar sensor model

The radar sensor has been ported to the PreScan Multi-Processing architecture:

  • During simulation it will be run as a separate process resulting in a better performance.
  • Usage of multiple Radar sensors has improved. Multiple sensors can simulate in parallel instead of serially.
  • Small sensor quality improvements have been implemented.
  • Updated GIDAS plugin

Support was added for the import of lane marker patterns. Marker lines from the GIDAS data will result in LinePlacedMarkers in the PreScan scenario.

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.

 

  • Fade and holes extended

Fade and holes can now also be applied to Road Markings, Priority Lines and Line Placed Markers.

 

  • Compilation Sheet Migration Dialog

For some PreScan blocks on the Compilation Sheet, the user can now choose whether the block is migrated (removing any user configuration) to the latest version of the PreScan block.

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.
