This modular approach enables you to expand Vicon MX as needed. The following sections illustrate some common Vicon MX architecture models.
PAGE 26
MXhardware_Reference.book Page 4 Monday, April 30, 2007 1:56 PM Introduction Large Camera-Count Architecture If your application requires more than eight MX Cameras, you must include additional MX Ultranet units in the Vicon MX architecture. If your system has an MX Net unit, you must include additional MX Net units along with MX Link units to connect these together. For descriptions of these system elements, see Vicon MX Architecture Elements on page 1-1.
PAGE 27
MXhardware_Reference.book Page 5 Monday, April 30, 2007 1:56 PM Introduction Integrated Third-party Application Architecture If your application integrates third-party analog capture, genlock, and timecode devices, you must include an MX Control, with the appropriate option card installed, in the Vicon MX architecture.
PAGE 28
MXhardware_Reference.book Page 6 Monday, April 30, 2007 1:56 PM Introduction Integrated V-series Cameras Architecture If your application integrates Vicon MCam2, VCam, SVCam, MCam(PAL), or MCam(NTSC) cameras supported previously by Vicon V-series systems, you must include an MX Bridge in the Vicon MX architecture (for descriptions of these system elements, see Vicon MX Architecture Elements on page 1-1). This integrated V-series cameras architecture is illustrated in Figure 1-4.

PAGE 39
MXhardware_Reference.book Page 3 Monday, April 30, 2007 1:56 PM MX Cameras Each MX Camera is programmed with firmware to control its operation and enable it to perform its own onboard grayscale processing. As all MX Cameras use the same firmware, a mixture of cameras with different image sensors can be connected to and run on the same Vicon MX system. Vicon MX automatically recognizes cameras and their relevant characteristics when they are plugged in.
PAGE 40
MXhardware_Reference.book Page 4 Monday, April 30, 2007 1:56 PM MX Cameras application depends on various factors, including the field of view (FOV), the aperture, and any lens filter fitted. Important Vicon Motion Systems has a policy of only using the best quality lenses with its cameras. Should you need to change lenses, please refer to Vicon Motion Systems or your nearest agent or distributor for advice. A variety of C-mount lenses as well as SLR (Nikon Bayonet) lenses are available for MX Cameras.
PAGE 41
MXhardware_Reference.book Page 5 Monday, April 30, 2007 1:56 PM MX Cameras 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.
PAGE 42
MXhardware_Reference.book Page 6 Monday, April 30, 2007 1:56 PM MX Cameras Another characteristic of the camera sensor is the image circle. This is the sharp circular image that the camera lens casts onto the sensor, as shown in Figure 3-4. Figure 3-4: Image circle The diameter of this image circle is the maximum area of usable quality image that the lens can produce. Most lenses produce their best image at the center of the lens, dropping off in performance towards the outer extremes of the lens.
PAGE 43
MXhardware_Reference.book Page 7 Monday, April 30, 2007 1:56 PM MX Cameras details on the MX Camera lens specifications in Appendix D Technical Specifications. Table 3-3 gives the formulae used to calculate the angle of view (AOV) and field of view (FOV) for camera and lens combinations. These formulae require the dimensions of the sensor area used for each of the MX Cameras at different frequencies.
PAGE 44
MXhardware_Reference.book Page 8 Monday, April 30, 2007 1:56 PM MX Cameras resolution frequencies given in MX Camera Specifications on page D-2, the sensor area is reduced due to vertical windowing, as described in Field of View on page 3-4. Aperture and Depth of Field Another significant factor in choosing a lens type is the aperture (also known as the f-stop value, f-number, and F#), which refers to the speed with which the lens can pass light in a given time.
PAGE 45
MXhardware_Reference.book Page 9 Monday, April 30, 2007 1:56 PM MX Cameras Unshuttered MX Cameras are potentially more susceptible to background light. Therefore, a more restrictive band-pass interference filter is fitted as standard to the these cameras, appropriate for each of the VR, NIR, and IR strobe units available.

MXhardware_Reference.book Page 21 Monday, April 30, 2007 1:56 PM Point Point A location in space specified by 3D coordinates. A trajectory (or segment of a trajectory) consists of a time-series of points. A point is stored in a .c3d file as three spatial coordinates and a residual, identified by a label. Points may represent the measured positions of real markers. In some Vicon application software, points may be virtual (created by modeling). The terms point and marker are often used interchangeably.

MXhardware_Reference.book Page 25 Monday, April 30, 2007 1:56 PM Spike Spike A point that lies to one side of an otherwise smooth trajectory. A spike appears as a sudden, dramatic rise or fall in graph data. Spikes often occur as a result of a poor reconstruction in a particular frame and can be eliminated using editing tools in Vicon application software. Also see Frame, Point, Reconstruction, and Trajectory.

MXhardware_Reference.book Page 28 Monday, April 30, 2007 1:56 PM Trajectory Trajectory The path though space that a moving marker follows. This reconstructed data is stored in a file as a time-series of points with the same label. A trajectory can be displayed in the 3D Workspace as a line through the position of a marker in the current field. A trajectory may consist of a single uninterrupted path or of a number of segments. The latter can occur when markers are obscured from view.

MXhardware_Reference.book Page 29 Monday, April 30, 2007 1:56 PM Vector Vector A quantity that has both direction and magnitude. For example, velocity is a vector quantity whose magnitude is a body’s speed and whose direction is the body’s direction of motion. Vicon application software uses vectors to describe and analyze elements of kinematic models of subjects or objects whose motion is being analyzed. Also see Kinematic model.
