After the preillumination the film is then
transported.
An integrated rechargeable power supply feeds the
camera with electricity. An external power supply
feeds the flash unit. For industrial application, the
ZEISS lenses Distagon 4/40 mm metric, Distagon
4/50 mm metric and Planar 2.8/80 mm metric belong
to the standard equipment.
To meet with all different requirements, the Rolleiflex
6008 metric system with its flash an preillumination
unit offers the use with a tripod as well as the hand
held recording. The camera can be used outside the
preillumination and flash unit with all features for
taking standard pictures.
3. APPLICATIONS
In the following, three measurement results are
presented:
Surface measurement
For controlling the tension situation on a conveyer belt
for coal, a surface of app. 1 x 1 m was signalised with
retro target in regular intervals. A calibrated scale was
used.
The bundle adjustment gives the following results:
(8 pictures, 659 unknowns, 3082 observations, 1
camera)
SIGMAO - 0.0007 mm
RMS x =0.0006 mm
RMSy =0.0006 mm
The object points were determined with following
accuracy (standard deviation):
SX =0.01 mm
SY =0.08 mm
SZ =0.01 mm
Fitting check for plane parts
For quality control of plane parts, it is necessary to
check certain parts before adjustment into the whole.
In this case, a large format camera Rollei LFC (230 x
230 mm) or Rollei R_Metrika (120 x 95 mm) / 1992
Peipe, Suilmann, Wester-Ebbinghaus / is used to meet
with the accuracy requirements. For testing purposes,
the Rolleiflex 6008 metric was also used in this
application.
In this test, the design of the retro target was
developed for a use of a large format camera. For an
automatic point determination with RS1 software the
size in the 60 x 60 mm pictures was too small. The
measurement had to be effected in the manual mode
and a lower accuracy was accepted.
The bundle adjustment gave the following results:
(14 images, 659 unknowns, 3082 observations, 1
camera)
SIGMAO = 0.0023 mm
RMSx =0.0019 mm
RMSy =0.0022 mm
SIGMAO = est. variance of unit weight
RMS x, RMS y = mean square residuals of image
coordinates
The object was determined with the following
accuracy (standard deviation):
SX =0.15 mm
SY =0.10 mm
SZ =0.09 mm
