    Journey in Time with Stereoscopy


    Hamburg is one of the most painful German cities during the Second World War. The volume of demolished houses was equivalent to the total volume of houses in Nuremberg, Augsburg, Ludwigshafen, Würzburg and Regensburg. The most powerful explosive ammunition of the time had rained from the sky. Between 18 May 1940 and 17 April 1945, a total of 213 airstrikes were carried out in Hamburg and a total of 107,000 high explosive bombs, 3 million fire bombs and 300 thousand phosphorus bombs were fired. Nearly 70 percent of the city's buildings were destroyed after this terrible bombardment.

    Detection of non-explosive bombs

    There are not so many aerial photographs taken during the war in any other city in the world. There are currently 30,000 known aerial photographs of Hamburg. With the help of these photos, the explosion-proof bombs can be detected.

    Another advantage, unlike Cologne or Berlin, was that there was almost no conflict during the war in Hamburg. This shows that the effects of the war came only from air strikes, for example, not a single artillery shot, completely airborne. (GEKV) President Thomas Otto.

     "GEKV" section is responsible for categorizing the potential risks of the construction sites in the municipality area in terms of ammunition availability. The classification is based on the evaluation of historical aerial photographs from the sources of both Allied and German armed forces from 1940 to 1946.

    "Before any construction work starts in Hamburg, it is necessary to review precisely whether unexplored unexploded bombs are lying on the planned construction site.".

    Interpreting Sensitive Stereoscopic Aerial Photographs

    We start travel through time with stereoscopy. With the help of a monitor, stereo work creates a vibrant, spatial and 3D platform 70 years ago about the state of the city.

    Aerial photos of war time, Schneider DigitalIt has been stereoscopically interpreted in a total of 20 workstations equipped with high-end stereo displays of the 3D PluraView type. This monitor has been working with the advanced passive 3D stereo and display technology of the pasif PLANAR is beam splitter series that has been retired many years ago. 3D PluraView beam separator technology offers full screen resolution up to 4K quality with the help of two displays.

    The most important part of the study is spatial 3D stereo representation. It allows us to distinguish whether a black dot on the image is a collapse or a height: A collapse may be an indication of a bomb that went into the ground but did not explode. Thanks to the detection of such places, sleeping bombs are no longer a threat.

    Stereoscopy makes it easier to see whether the intermediate floors are found in damaged buildings. If there are still intermediate floors, this part of the space is no longer suspicious, but it is absolutely doubtful if none of the floors is left. In addition, it helps to analyze photos from different regions of the same region.

    We wanted to summarize the other features of the product for you.
