2.3.1 Inputs
2.3.1.1
Camera Model
The “Camera Model”
4
field displays the active camera model with its hidden parame-
ters from the internal database. While pressing the “Select” button
5
, the camera
model parameter database window will come up to select a new camera model, add a
new camera, delete a camera or change the parameters of a camera model. You will
find more about this issue in chapter 2.4.
2.3.1.2
Focal length [mm]
The value of focal length
6
complies with the value engraved on the lens used. When
using zoom lenses without engraved values between minimum and maximum focal
length, it is a good idea to use either the min. or max. value. Misrepresentation of the
input values may result in difficulties while stitching the panorama (wrongly calculated
horizontal/vertical AoV for one picture, step size from one picture to the other and
overlaps)
14/19
.
Changing the focal length
6
can be done by overwriting a given or the default value.
The decimal separator is accepted as a comma (
,
) and point (
.
) as well. Also values
like 88, without decimal separator and fraction, are accepted.
The Panorama Calculator is supporting 10 vertical rows for spherical panoiramas. For
SLR cameras focal length listed below are convenient.

2.3.1.3
Min. Overlap between Columns (H)
The "Min. Overlap columns (H)" is given in
7.
The default value is 25% and can be
changed with the arrows
8
attached to the mask. With the defined "Min. Overlap Col-
umns (H)"
7
, the calculated overlaps in "Output Horizontal"
26
are at least equal or a
bit larger as defined in
7
(with some exceptions). While rounding the "No. of Pic. (H)"
for a given row, sometimes the overlaps can be slightly less than defined.
Note: Are the calculated overlaps in a row not as expected (to small), just increase the value
in the input field
7
until they match your specification. Possibly at the same time the number
of rows will be increased too.
2.3.1.4
Min. Overlap between Rows (V)
The overlap between rows (P/P [%])
19
in "Outputs Vertical", are at least equal or a bit
greater as defined
9
. The default value is 25% and can be changed with the arrows
10
attached to the mask. The overlap (P/L [%]) is sometimes smaller than defined in
9
.
Note: While changing the min. overlap vertical in the input field
9
, possibly the horizontal
overlaps and the horizontal number of images in a row will change too.
