Creating Dynamic Camera Sensor

The following procedure helps you create a dynamic Inverse simulation of a Camera sensor.

In this procedure, only the Camera sensor will move according to the Trajectory file you input. Anything you add in the simulation (geometries, sources, sensors) will be static.
Note: The procedure highlights the main steps with a focus on the dynamic parameters. If you need more precision on the different features click the related feature links.

To create a dynamic Camera sensor:

  1. From the Light Simulation tab, click System > Camera .
  2. From the Mode drop-down list, select Photometric/Colorimetric to enable the advanced definition.
  3. Define the Camera sensor parameters, and more specifically:
    • the Trajectory file: describes the different positions and orientations of the Camera sensor in time. It is not mandatory as the Camera sensor does not have to move.
    • the Integration: corresponds to the time needed to get the data acquired by one row of pixels.
    • the Lag time: corresponds to the time difference between two rows of pixels to start the integration.

  4. From the Light Simulation tab, click Inverse .
  5. Define the Inverse simulation parameters, and more specifically:
    • Set Timeline to True
    • Set Start time of the Timeline
    • Add the Camera sensor to the simulation
  6. Click Compute to launch the simulation.
The Inverse simulation generates a spectral exposure map (*.xmp) for the Camera sensor. This map corresponds to the acquisition of the Camera sensor and expresses the data for each pixel in Joules/m²/nm.
