Zusammenfassung:The invention relates to a calibration and testing field for digital cameras mounted on unmanned aerial platforms. According to the invention, the calibration and testing field consists of points of 3D coordinates, determined with an accuracy in the range of millimeters, using a full station, and placed in different planes, materialized in the terrain while taking the pictures needed for the calibration process, as geometric shapes that can be automatically identified and measured, the digital camera being tested by a comparative analysis regarding the accuracy and the detail of a 3D model created based on the pictures taken, a cloud of reference points of high accuracy resulting from the measurements achieved with a terrestrial laser scanner being also considered for the comparative analysis. Invenţia se referă la un câmp de calibrare şi testare a camerelor digitale montate pe platforme aeropurtate fără pilot. Câmpul de calibrare şi testare, conform invenţiei, constă din puncte de coordonate 3D, determinate cu o precizie de ordinul milimetrilor, cu ajutorul unei staţii totale, şi amplasate în planuri diferite, materializate pe teren în timpul preluării imaginilor necesare procesului de calibrare prin forme geometrice care pot fi identificate şi măsurate automat, testarea unei camere digitale fiind realizată prin efectuarea unei analize comparative asupra preciziei şi nivelului de detaliere a unui model 3D creat pe baza imaginilor preluate, pentru studiul comparativ fiind luat în considerare şi un nor de puncte de referinţă cu precizie ridicată, rezultat în urma măsurătorilor efectuate cu ajutorul unui scaner laser terestru.
