MXhardware_Reference.book Page 3 Monday, April 30, 2007 1:56 PM Introduction Vicon MX Architecture Models You can combine Vicon MX and third-party elements to create an architecture that meets your application requirements. This modular approach enables you to expand Vicon MX as needed. The following sections illustrate some common Vicon MX architecture models.
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.
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.
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.
MXhardware_Reference.book Page 1 Monday, April 30, 2007 1:56 PM 2 MX Bridge 2 This chapter describes the physical structure of the MX Bridge, including its connections to other Vicon MX components and to supported V-series cameras. The MX Bridge provides the interface between Vicon MX and any MCam2, VCam, SVCam, MCam(PAL), and MCam(NTSC) cameras supported previously by Vicon V-series systems.

MXhardware_Reference.book Page 1 Monday, April 30, 2007 1:56 PM 3 MX Cameras 3 This chapter describes the MX Cameras, including lenses, controls and connectors, and associated strobe units. Warning There are no internal operator adjustments inside any components of the MX Cameras. Refer servicing to qualified personnel. Camera Types Vicon MX systems can include any of a range of proprietary Vicon motion capture cameras: F-series, MX+, and MX.
MXhardware_Reference.book Page 2 Monday, April 30, 2007 1:56 PM MX Cameras as shown in Table 3-1. Different types of strobe units can be attached to cameras to suit specific on-set or laboratory lighting conditions. Table 3-1: Vicon MX motion capture camera ranges Resolution MX F-series MX+ MX 4 Megapixels MX-F40 MX40+ MX40 2 Megapixels MX-F20 MX20+ — 1.3 Megapixels — MX13+ MX13 0.3 Megapixels † MX3+ MX3 † The MX3+ (MX-3+) is available for use with the F-series range of cameras.
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.
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.
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.
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.
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.
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.
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.
