Step 2 Take Background Picture

Before performing a sound mapping measurement, a background picture must be taken. In order

to do this, plug the digital camera on a USB port and click the “New Measure” button on the

software interface or on the intensity probe:

This will launch the background picture interface:

This interface allows adjusting the camera parameters, such as focus, luminosity and contrast. It

also allows checking for appropriate probe detection: place the probe with the visual tracking

device in the field of view of the camera and a green polygon should be drawn on the detected

probe. When satisfied with the image, click OK to accept and return to the main interface.
