Fotogrammetrian kehitykseen vaikuttaneita henkilöitä:



Sir David Brewster (1781-1868)

- In 1849 Brewster invented the Stereoscope, a viewer for stereoscopic prints. These became popular items in Victorian drawing-rooms. His book (The Stereoscope, its history, theory and construction) is still a good introduction to stereoscopic photography, though the author rather spoilt it by his unpleasantries concerning Wheatstone, who had actually invented stereoscopy.

Jacopo Chimenti

- About 1600 a Florentine painter Jacopo Chimenti produced what was probably the first hand drawn stereo-picture pair.

Édouard Gaston (Daniel) Deville (1849-1924)

- French-born Canadian surveyor of Canadian lands (1875-1924), who perfected the first practical method of photogrammetry, or the making of maps based on photography. Deville served in the French navy, conducting hydrographic surveys in the South Sea islands, Peru, and elsewhere until 1874. He then went to Canada, where he was appointed (1875) inspector of surveys in the province of Quebec. In 1881 he became inspector of Dominion land surveys and four years later surveyor general. Deville devised a system of making maps by plotting intersections from photographs taken from tripods on the ground. Among his several articles and books is Photographic Surveying (1895).

- In the mountain region of the West he used monoscopic terrestrial photogrammetry and and the method was applied in the Canada-Alaska boundary survey of 1893. In 1895 he conceived, and in 1902 he described, a mapping instrument incorporating a modified Wheatstone stereoscope for use with terrestrial stereosphotography. From 1920 on, he turned to mapping from oblique aerial photographs of eastern Canada's lake-strewn plains. For the transfer of photographic detail into correct map position, he made use of perspective grids prepared in incremental steps of flight altitude and camera tilt, as developed by McKay. This procedure became known as the "Canadian Grid Method". Over 100,000 exposures were taken before 1930 and their information content was transformed into planimetric maps. The magnitude of these operations and Deville's determination to improve the accuracy of the mapping process led to the installation of a camera testing and calibration laboratory (National Research Council 1952). Experiments began in 1937 with multi-lens cameras. These were soon replaced by single wide-angle types. Extensive mapping operations followed, based on the use of graphical radial-line triangulation.

Eduard Dolezál (1862-1955)

- Prof. Dr. Eduard Dolezál was born the son of a weaver on 2 March 1862 in Budwitz, Moravia, studied mathematics and physics in Vienna and in 1889 became a teacher of mathematics at the Technical Secondary School in Sarajevo, Bosnia. In 1905 he was offered a chair in practical geometry at the Technical University in Vienna. Three years later, in 1908, he was elected president of the University.

As early as 1896 he wrote a paper about "The Application of Photography to Practical Measuring Tasks". On 5 May 1907 he founded the Austrian and on 4 July 1910 the International Society for Photogrammetry. He served as first president of ISP until 1926. Dolezál founded the International Archives for Photogrammetry and edited the first six volumes (1908 - 1923). He also organized the first International Congress for Photogrammetry (24 to 26 September 1913) in Vienna. He died, showered with honours, on 7 July 1955 in Baden near Vienna. Those who knew Dolezál also spoke highly of his social awareness, his visions, his methodical work, all of which aimed at international cooperation.

Sebastian Finsterwalder (1862-1951)

- Mit seinem sicheren Gespür für praktische Anwendungen nutzte Finsterwalder die Darstellende Geometrie beim Aufbau der Photogrammetrie. Als einer der Ersten entwickelte er Verfahren zur Rekonstruktion räumlicher Objekte aus Photoaufnahmen. Seine bahnbrechende Arbeit ,, Die geometrischen Grundlagen der Photogrammetrie`` (erschienen 1899 im Jahresbericht der Deutschen Mathematiker Vereinigung) ist heute noch lesenswert. Er beschränkte sich nicht auf Untersuchungen am Schreibtisch. Er war zugleich ein Pionier bei geodätischen Vermessungen im Gelände, insbesondere bei Luftbildaufnahmen im Hochgebirge. Er konstruierte einen Phototheodoliten, dessen Ideen die Zeiss-Werke in Jena nutzten, und aus seinen Meßergebnissen entwickelte er die zum Verständnis der Alpengletscher wichtige ,, geometrische Theorie der Gletscherbewegung und Moränenbildung``. Sein Bestreben, die Photogrammetrie auch im amtlichen Vermessungswesen einzuführen, fand zuerst beim k.u.k. Militärgeographischen Institut Anerkennung und Förderung. Zur Beschaffung von Luftbildaufnahmen war er ein eifriger Ballonfahrer, und als solcher gehörte er zum Beraterkreis des Grafen Zeppelin. Hier seien auch seine Arbeiten zur Aerodynamik erwähnt - auch daß er Mitbegründer der Akademischen Fliegergruppe (Akaflieg) der TH München war.

Johannes Kepler (1571-1630)

- About 1600 the German astronomer Johannes Kepler gave a precise definition of 'stereoscopy'.

Albrecht Meydenbauer (1834-1921)

- Die Architekturphotogrammetrie geht auf eine Erfindung von ALBRECHT MEYDENBAUER (1834-1921) zurück. 1858 kam ihm die Idee, die herkömmliche Bauaufnahme von Hand durch die geometrische Auswertung von photographischen Bildern zu ersetzen. Seither arbeitete er für die Vervollkommnung und Anerkennung des von ihm entwickelten Meßverfahrens. Zugleich verfolgte er das große Ziel, ein Denkmälerarchiv einzurichten, das Baudenkmäler in meßtechnisch auswertbaren photographischen Bildern dokumentieren sollte. 1885 war es schließlich so weit, daß in Berlin die Königliche Meßbildanstalt gegründet und MEYDENBAUER zu ihrem Leiter berufen wurde. Seiner Weitsicht ist es zu verdanken, daß uns heute viele nationale und internationale Baudenkmäler in Meßbildern erhalten sind.

Tournachon (Nadar)

- The caricaturist, photographer, and fashionable sports ballonist Tournachon (nicknamed Nadar) took his camera and darkroom aloft, became the first aerial photographer, and ardently agitated to use his art for mapping the countryside (1858). Emperor Napoleon III ordered Nadar in 1859 to furnish reconnaissance photography in preparation for the battle of Solferino in northern Italy.

Wheatstone Wheatstone viewer Sir Charles Wheatstone (1802-1875)

- His particular contribution to photography was in his development of stereoscopy; in 1838 he described the theory of stereoscopic vision and his invention of the stereoscope to the Royal Society. His mirror stereoscopic viewer required that both pictures in the pair be reversed laterally. The advantage of the arrangement was that one could cope with large pictures, which is why the principle is still in use today when viewing Xray stereoscopic pictures.
