For the first test measurement with the DCS 460 described above, a comparison with the results of measurements of
the same automobile part performed with two other cameras can be given. A block of 10 images recorded with a 1500 x
1000 pixel Kodak DCS 200 camera resulted in 3-D coordinates with a standard deviation of s, = 0.027 mm, s, = 0.029
mm and s, = 0.036 mm, a relative accuracy in object space of 1 : 90000 after bundle adjustment. A block of 7 images
acquired with a film-based Rolleiflex 6006 metric camera and measured in a Rolleimetric RS1 réseau scanner yielded a
similar outcome, s, — 0.025 mm, s, = 0.026 mm and s, = 0.046 mm. These results point to the substantial increase of
accuracy achievable with the DCS 460.
4. CONCLUDING REMARKS
The new high resolution Kodak DCS 460 still video camera with a 3060 x 2036 pixel imager proved to be a very useful
digital image acquisition tool for close range photogrammetry. The camera is especially suitable for off-line single-
sensor applications in industrial metrology, but also for architectural photogrammetry due to the excellent image reso-
lution. The handling of the DCS 460 is user friendly. The removable hard disk cards serve for fast data transfer and
enable the user to take an extended number of images by changing the cards.
From the viewpoint of close range photogrammetry, the DCS 460 is a relatively expensive small format camera which
offers accuracy figures comparable to a large format film-based camera.
ACKNOWLEDGEMENT
The author would like to thank the Kodak AG Stuttgart for providing the DCS 460 camera.
