3D Optical Digitizers
Patterned light is projected onto subjects; deformation is recorded by an off-set camera. Triangulation calculates a 3D mesh. Fast, accurate and adaptable for human portraiture.
3D Laser Scanners
A laser line moves over subjects' surfaces; an off-set camera records deformation. Triangulation calculates a 3D mesh. Slower, but higher accuracy enabled for static objects.
3D Mechanical Digitizers
Mechanical arms physically probe objects, guided by the user; points are recorded on the surface of subjects. Intuitive but slow. Unsuitable for delicate objects.
3D Scanning software
View, edit and export scan data efficiently and accurately. Triangulation, registration and merging algorithms, polygon editing, CAD conversion, model export for web viewing.

VI-9i - 3D Laser Scanner
The newly developed VI-9i uses a new hardware design and an improved measurement
algorithm to provide 4 times the measurement accuracy of our previous models
(to 50µm), enabling 3D measurement of automobile parts and other objects
formed by casting, pressing, moulding, etc.
Konica Minolta VI-9i
The VI-9i non-contact 3D digitizer provides high-speed and high-accuracy
3D measurement of dies, cast and forged products, and stamped and plastic-molded
products. The 9i excels at shape evaluation, tool and die qualification, and
quality inspection during prototype creation and the during the production
processes. The 9i is an ideal way to capture the shape and dimensional data
of design models and prototypes in design drawings for reverse engineering
purposes.
When used for reverse engineering or CAE, the VI-9i easily and accurately
converts the shape of a product into 3D digital data. Using the VI-9i for
inspection or CAT contributes to the early detection of shape problems, provides
rapid feedback on design, and eliminates unnecessary work in downstream processes.
As a result, it accelerates the entire manufacturing process.
Contrasting subjects demonstrating improved accuracy
and flexibility
Measure targets of any size
Konica Minolta employed its expertise in optical engineering to develop interchangeable
high performance, dedicated lenses. As a result, TELE, MIDDLE and WIDE lenses
can be selected to accommodate the size of the measurement target. (Input
range in X, Y and Z directions: 93 x 69 x 26 mm to 1495 x 1121 x 1750 mm)
Point & Shoot, Leave detailed settings to the 9i
Konica Minolta's AF/AE technology, developed through its expertise in camera
manufacturing, relieves users from the need to determine the exact measuring
distance. Moreover, the system automatically determines the optimum laser
power for the surface conditions of the target. (Scan Range : standard mode
0.6 to 1.0 m, Extended mode 0.5 to 2.5 m)
High speed and high accuracy
Start the measurement by framing the scan area on the LCD Viewfinder of the
VI-9i unit or on the host computer’s display . Each scan requires only
2.5 seconds to acquire accurate 3D data.
Standards-Traceable performance
Konica Minolta supports compliance with ISO 9000. Manufacturers using VI-9i
for QC applications can receive test report of the accuracy of each 9i, traceable
to national standard. Thereby ensuring that our measuring instruments and
your process conform to ISO 9000 requirements.
*On request, Konica Minolta can provide a test report for each 9i unit. This
test report is created by evaluating the measurement accuracy for all 3 lenses
of each 9i using our Reference 3D Chart, an artifact traceable to national
standards, and thus can be used as documentation for conformance with ISO
requirements.
Quick, easy editing
Missed a spot? You’ll see it immediately and be able to scan any voids.
You can check the measured 3D data in real time on the preview screen. This
allows for sequential framing, measurement, and alignment of the data. Thanks
to the improved processing speed and the new graphical user interface specifically
developed for the VI-9i, even large amounts of measurement data can be merged,
edited and converted into general 3D data format with greater speed and ease.
Photogrammetry System PSC-1 (optional)
VI-9i captures large parts (> 1 meter) easily. When PSC-1
is used with the 9i, the combination enables the user to capture both high-detail
and large parts. In the past, the alignment of multiple scans was error prone,
making it hard to achieve high-detail and high accuracy on large parts. P-N
automates the registration process, and removes the tolerance stack-up inherent
in best-fit techniques.
When measuring a large part maximum detail is achieved by dividing the part
into several scanned regions. With PSC-1 the individual scans are aligned
(registered) automatically, with higher alignment accuracy than has been possible
before.
The user will place scale bars around the object to be scanned
(the “subject”) and attach reference markers to the subject. With
the dedicated digital SLR, the operator takes pictures of the subject, being
sure to include both the coded markers and dimension-controlled scale bars
. Based on these pictures, the coordinates of the reference markers are determined
with high accuracy using photogrammetric technology, creating a sparse point
cloud of the subject (i.e., a 3D “Constellation” in the shape
of the subject).
Now it’s time to scan the surface detail using the
9i. As each VI-9i scan is captured, it is automatically aligned to the PSC-1
data cloud created in step 1. The VI-9i reads the target data and places the
scans in their correct orientation. Even relatively smooth shapes such as
fenders or door skins are accurately aligned because the alignment does not
depend on
complex surface geometry. Result: a more accurate model.
In addition to being more accurate, PSC-1 saves time. Firstly, any voids are
apparent immediately; aligned data enables the user to scan any missing surface
data. Secondly, since the scans are aligned to the photogrammetric point cloud
(rather than to each other), there is no need to overlap scans. Furthermore,
if two areas of interest are separated by an unimportant area, the operator
no longer needs to scan the intervening area, saving more time.
High speed, high precision, and
Measurement accuracy of ±50µm
The VI-9i requires only 2.5 seconds per scan to acquire accurate 3D data. Consequently,
the VI-9i is ideal for accuracy verification and shape inspection of cast, forged,
and pressed automotive parts and plastic-molded automotive parts. Give us your
part, and we’ll prove it to you.
The new Field Calibration system, negates inaccuracies caused by lens exchange
or environmental changes. A simple calibration procedure before use assures
the optimal performance from the 9i.
High-accuracy measurement of even large parts
The VI-9i can be combined with PSC-1 , Konica Minolta’s optional photogrammetry
system. The combination of the VI-9i and PSC- 1 provides for fast and accurate
measurement and data assembly even for relatively large targets - such as car
body portions, doors, bumpers, and instrument panels. It is also effective to
correctly align surfaces having no characteristic shape, such as projections
and depressions. (Typical subject size ranges from 0.5 to 2.0 m and larger)
Measurement principle
The VI-9i is based on the principal of laser triangulation. A target is scanned
with laser stripes . The CCD camera receives the light reflected from the surface
of the subject. Surface shape measurements of the subject are obtained through
triangulation, and converted into a 3D polygon mesh.
The VI-9i measures 640 x 480 points with one scan, simultaneously acquiring
surface shape data and color image data.
