VRSG Sensor Views

Back to VRSG Dashboard Interface      

record

On the Sensor tab of the VRSG Dashboard you specify characteristics of the VRSG IR scene display, such as simulated noise, contrast, and blur and whether to display simulated A/C banding. The Sensor tab is displayed in the Dashboard only when the Enable Sensor Modes checkbox is selected on the Startup Parameters tab at the start of a VRSG session.

The post-processing effects are:

  • Noise - Adjusts the amount of artificial noise of the scene in all sensor modes.
  • Focus - Adjusts the intensity of optical focus (blur) of the scene in all sensor modes.
  • Level - Adjusts the brightness of the scene in all sensor modes.
  • Gain - Adjusts adjusts the contrast of the scene in all sensor modes.
  • Digital Zoom - Adjusts the amount of artificial blocky, aliased artifacts of a sensor as the pixel boundaries become visible at high levels of zoom.
  • Motion Blur - Adjusts the simulated blurred or smeared appearance of objects along the direction of relative motion. A small degree of blur is recommended, as it makes the scene appear less crisp and more characteristic of an IR sensor.
  • A/C Banding - Displays the scrolling horizontal stripe that simulates the banding produced by power supplies that have frequencies dissimilar to the vertical retrace period of the monitor. When you select this option, also select which sensor view on which you want the banding to appear.

The IR rendering options selectively control the brightness value for various elements within an infrared scene, and control whether the white hot or black hot scenes are displayed in green or in black and white. The IR Configuration option, available as part of VRSG’s physics-based IR, enables you to select an IR configuration file, or profile, that was created with VRSG’s IR Setup utility for physics-based IR simulation.

Sensor characteristics can also be controlled programmatically through the Common Image Generator Interface (CIGI) version 3.2, as described in the MetaVR User's Guide.

To render a physics-based simulated infra-red (IR) scene, use MetaVR's physics-based IR.
