Replacing the Lens and Field Calibration
With the VIVID 9i, three types of lens are available: WIDE lens, MIDDLE lens and TELE lens. Be sure to
mount the lens that best matches the subject’s size and distance. Before taking scans of a subject, most suitable
lens for the size of the object and distance must be used.
Note
After changing the lens, you need to recalibrate using the field calibration system. For Field Calibration, refer to page
32.
Relationship between Measurement Distance and Object
Select the most suitable lens by referring to the table given below.
M

Field Calibration
The field calibration on this unit is done using the Field Calibration System.
Periodic field calibration is recommended to maintain measurement precision.
Note
• Always carry out field calibration when changing lenses.
• The Field Calibration System that corresponds to the type of lens the unit is equipped with must be used when conducting field calibration.
• This unit and the Field Calibration System are paired, so it is not possible to correctly calibrate it when the serial
numbers differ. Use the unit and Field Calibration System combination that have the same serial number.

Executing Field Calibration
The Field Calibration System is made up of the Field Calibration System Section and the Frame Section. It is
necessary to assemble it when it is to be used for the first time or after it has been temporarily disassembled to
move the Field Calibration System, etc. In addition, it is necessary to attach the Field Calibration System to the
main unit in order to carry out field calibration.
M
emo
VIVID 9i/VI-9i has been calibrated at 20ºC. The allowable operating environment is 10ºC to 40ºC, but we recommend
that you execute Field Calibration or scan the objects in environments where ambient temperature is 20ºC (68ºF).
Assembling the Field Calibration System
[Procedure]
Install the Frame Section.
1
Install the Frame Section in a secure location with sufficient space.
Note
For the place that is necessary to install the Frame of the
Field Calibration System, see page 33 of this instruction
manual. A “Calibration Area” is also required for executing the calibration.
Adjust the Height of Rubber Feet to Stabilize the Frame Section.
2
The Frame of the Field Calibration System is designed to be used on a sufficiently wide, stable, flat surface. However, even if a sufficiently wide space is available, the surface may not be completely flat, resulting in one or more of the rubber feet of the frame not being in contact with the surface. To solve this
problem, the feet have been equipped evenly with a mechanism to allow their height to be adjusted.
M
emo
All 6 rubber feet have height adjustment mechanisms.
Note
• Adjust a height of the rubber feet without any item on the frame during the procedure for setting up the frame
of this system.
• When transporting this system, set the rubber feet to their lowest height to avoid damage to the shopping box.
1Turn the lock nut counterclockwise to unlock the
rubber foot block.

Unlock the rubber
foot block by turning the lock nut
counterclockwise.
2Turn the lock nut counterclockwise to unlock the
rubber foot block.
M
emo
Turn clockwise for lower heights and counterclockwise for
higher heights.
Note
Because there is no preventive structure, moving the rubber foot block more than adjustable range may cause the
rubber foot block to fall off. In this case, screw the rubber
foot block onto the stopper unit clockwise.
3After adjusting the height correctly, move the lock
nut to the stopper unit by turning it clockwise and
lock the rubber foot block.

Explanation of Measuring Principle
Measuring Principle
The VIVID 9i uses the light-stripe method to emit a horizontal stripe light through a cylindrical lens to the object. The reflected light from the object is received by the CCD, and then converted by triangulation into distance information.
This process is repeated by scanning the stripe light vertically on the object surface using a Galvano mirror, to
obtain a 3D image data of the object.
In addition, a color image of the object is also obtained by scanning the CCD through a RGB filter while the
stripe light is not emitted. (A band pass filter is used when stripe light is emitted.)

Explanation of Measuring Principle
High-Speed Image Processing Circuit
The stripe light is scanned on the CCD image plane at one horizontal line per frame, and the CCD is driven so
that the block readout start position is shifted one line per frame.
Approximately 600 frames are acquired.
· CCD drive rate: 12.5MHz
· Block readout: 125 lines
· Data acquisition speed: 2.5 sec.
The output signal from the CCD is then converted into a digital signal, which is then subjected to digital signal
processing. The signal processed data is finally saved in the frame memory.

Time center of gravity and Space center of gravity
Time center of gravity is the center of gravity of the variation in the LD light passing CCD’s one picture element over a period of time.
Space center of gravity is the center of gravity of the spatial variation in the LD light on the CCD at a certain
time.
With this instrument, 3D images are obtained by calculating the Time center of gravity of each picture element
of CCD. Intersection of the viewing angle of each picture element of the CCD and passing angle (time) of the
stripe light is calculated.
Compared to the Space center of gravity, use of Time center of gravity can reduce influences of sensitivity variation of CCD’s picture elements and variation of brightness of the object.
