MX Cameras

Vicon MX Hardware System Reference 3-5

Normally, the AOV is calculated based on the known focal length and

sensor size. This in turn determines the FOV, based on the distance

(L) to the object being captured. Figure 3-3 illustrates how the FOV

is calculated.

Figure 3-3: Field of View calculation

The sensor area used for capturing data through each MX Camera

determines the maximum FOV available for a particular combination

of camera and lens. The area of the sensor is determined by its

horizontal width (h) and vertical height (v).

The capture frame rate for each MX Camera can be configured in the

Vicon application software (for details, see the software

documentation). The configured frame rate will also affect the field

of view. Higher camera frame rates may make vertical windowing of

the sensor necessary such that the sensor area used for capture is

reduced in comparison to lower camera frame rates.
