The special digital HDR camera records rooms fully spherically and therefore in all directions at an angle of 360 degrees horizontally and 180 degrees vertically for fully spherical images.
The "High Dynamic Range" (HDR) process makes it possible to view the recorded image data in a very wide range of different brightness values and very conveniently compensate for differences in brightness, such as those between light and shadow or between room walls and window surfaces. In contrast to previous recording options in conventional analogue and digital photography, in which bright image areas (e.g. windows) were irreversibly overexposed and dark image areas (e.g. walls or room corners) were underexposed, making it impossible to see details, HDR allows individual image areas to be brightened or darkened at any time in the existing image recording.
In addition to the 16 mm standard fisheye lens, the technology can also be used with 28, 50 and 105 mm interchangeable lenses.
In addition to the option of zooming in and out, the system also has a fully calibrated photogrammetric measurement technique, although this requires two images to be taken 60 cm apart. The image data of the two images is stored in such a way that measurement sections can be displayed with dimensions in the fully spherical overall image by selecting the measurement points accordingly.
However, the camera lens is calibrated at the factory for a measuring range of 1 to a maximum of 10 meters.
In addition to the original test procedure for combining color photographs with 3D laser scans, this procedure is of course also made available from here to the state's police departments in relevant investigative cases, especially at crime and incident scenes.
The system is a valuable addition to the classic recording of crime and incident scenes. In addition to two-dimensional photography and videography, it is now possible to depict a location even more objectively and photorealistically. From a specific location, an all-round view is guaranteed that allows any of the above-mentioned individual perspectives and no longer depends on subjectively selected photo angles and locations or on subjective direction of a video. This means that partial views that influence the overall impression can be avoided, as is the case in photo and film direction for dramaturgical reasons, for example.
In this way, the police, the public prosecutor's office, the courts and the defense can be offered a factually realistic overall depiction of a location, which reduces text descriptions to a minimum, reproduces the scene of the incident photographically in a timely manner and thus makes time-consuming and costly site visits unnecessary.
