7. Evaluate Clip

You view the ingested run actors and trajectories in the Visualizer pane.

7.1 Visualizer display size and view preferences

You can change the Visualizer's display size and view using various icons.

7.1.1 Adjust display size

  • To expand the space the Visualizer takes, click the maximize icon.

The Traces panes collapse.

You can reopen any pane and change the layout as required.

  • Use the icon to restore the Traces panes.

7.1.2 Change layout

Use the Visualizer Layout Views icons to change the layout:

  • Click the Horizontal view icon to switch to the horizontal layout.

  • Click the Vertical view icon to switch to the vertical layout.

  • Click the Reset to Visualizer-focused layout icon to reset the layout.

7.1.3 Expand and collapse panes

You can also minimize and expand individual Visualizer panes using the Expand and Minimize icons.

7.2 Viewing the ingested scenario

  1. Enable the Compare to noisy data toggle to show both the original Imported Clip (noisy) and the Ingested Clip (denoised); use the toggle to turn each on and off for side‑by‑side inspection.

    To ensure more realistic and complete scenarios, stationary vehicle extrapolation automatically extends detected stationary vehicles (primarily parked cars) across the full duration of the clip. The denoiser preserves their last known position and assumes zero velocity to maintain temporal consistency throughout the scenario.

    The image below illustrates the Foretify Manager view, where a parked vehicle has been automatically extrapolated over the entire clip duration by the denoiser.

  2. Click the View Tools icon.

  3. To view actors and trajectories to analyze movement patterns, in the Actor Properties dropdown menu:

    • Select Selected Actor to view a single trajectory.

    • Select All Actors to view all actors' trajectories.

  4. Check or uncheck options from the available View Tools options to customize what appears in the display:

    To help you focus on the map data relevant to your scenario without cluttering the map, five options are available under Additional Map Data, making it easier to interpret vehicle behavior and analyze runs in context of the map elements.

    • Lane directions: Display lane direction indicators so you can see the permitted travel directions for each lane.

    • Speed limits: Display speed limit signs to help evaluate compliance and driving context.

    • Traffic controls: Traffic control elements are separated into three independent toggles — Traffic lights, Stop signs, and Yield signs, making it easy to visualize the effects of traffic controls during the run. Each toggle is only available if the corresponding data exists in the current run.

    • Traffic lights: Display the location of traffic lights and their corresponding dynamic, colored traffic light-state lines. The line colors change according to the current traffic light state to indicate whether vehicles are expected to stop (red) or can proceed (green line).

    • Stop signs: Display the location of stop signs and their corresponding stop lines where vehicles are required to stop.

    • Yield signs: Display the location of yield signs to indicate where vehicles should slow down and yield for oncoming traffic before proceeding.

  5. When you click Edit to open the scenario editor, you can select to view scenario actors only.

7.3 Viewing Traces of compared actors

Use the Traces panel to visually compare the behavior of actors in noisy (raw) and denoised (processed) data.

  1. Enable comparison mode:

    • In the Visualizer, toggle Compare to noisy data to display both the original (noisy) and denoised actor trajectories.
    • Noisy data is typically shown in pink, while denoised data is shown in blue.

  2. Select the actor of interest:

    • Use the actor selection bar in the Traces panel to choose the actor you want to analyze.
    • Actor IDs are mapped between noisy and denoised versions, allowing direct comparison.

  3. View and analyze the traces:

    • The Traces panel displays synchronized time-series plots for key parameters:

      • Speed
      • Acceleration
      • Distance
      • Position
      • Orientation

    • These traces show both the noisy and denoised values for the selected actor, making it easy to spot differences and assess the effectiveness of the denoising process.

  4. You can choose to display traces for all actors or focus on a single actor. This is useful for understanding scene-wide effects or isolating specific issues.
