Findclouds Manual 17
"Desired" resolution. When the masked resolution exceeds the desired resolution, the software will
scale the image down to desired resolution. Also when there are images with different resolutions
this can be useful to get normalised images with the same size. When there is no desired size
given (by empty input) the masked size will be used.
Normal Exposed/ Underexposed
The extensions to identify images that belong together for high dynamic evaluation by normal exposed and
underexposed image. This way of evaluation causes a better evaluation of the area near the sun. Please be
aware not to fill in the separative underscores - they don't belong to the extension.
Latitude / Longitude / Altitude
These values specify the position of the Sky Imager They are necessary to calculate the position of the sun,
when evaluating the "near sun area" by underexposed images. When the position is not known, e.g.
"Google Maps" could be used to find out, where the Cloudcam is placed.
[Mirror],
when activated, the software mirrors the image when loading it. This changes the "upward
looking" image to a "ground based image", as if the point of view is changed from ground to above the
clouds. The new CMS All Sky Imager provides images, that are already mirrored, so this option must be
deactivated, when "ground based images" are desired and ASI is in use.
[ASI]
activates a non-linearity equalisation for the new CMS All Sky Imager. While the fisheye Images of the
Cloudcam follow a strict linear ratio of angle to distance on image, there is a distortion on ASI images, that
needs to be equalised.
[Choose Photo]
loads an image made by the current Cloudcam. This image must be used for further
adjustments and will activate buttons [Center] and [Zenith] when it was loaded successful.
[Angle]
will switch to adjustment of the Cloudcams offset angle.
[Center]
will switch back to adjustment of centering and calibration of fisheye area and deactivate
accentuated contrast. It allows to centre up the image and adjust size of fisheye area.
[Zenith]
will switch back to adjustment of offset angle and show not equalised image without field of view
circle.
[Horizon]
window for input of horizon.
