The paper considers an innovative project for the development of video surveillance systems and management of agrotechnological processes using a time-of-flight camera. The authors have carried out an analysis of modern 3D information technologies for three-dimensional observing agroobjects. The analysis results have shown main opportunities and advantages of using time-of-flight cameras for more accurate positioning and performing agrotechnological operations by mobile and robotic units. The paper provides a mathematical description of the model for the implementation of the time-of-flight technology on photomatrix receivers of optical radiation. The authors have determined areas of wide application of time-of-flight technologies in industry and agriculture and analyzed the main directions of applying time-of-flight cameras in agricultural technologies. Particular attention is paid to the development of specialized search and conversion functions of an unmanned aerial vehicle for effective utilization in agriculture, as the most important task of further development of localized agrotechnologies. The authors have identified tasks of modernizing the functions of an unmanned aerial vehicle to be adapted to the farm production technology, especially, crop production, livestock and nature management, aimed at improving flight-landing, search-recognition and manipulation-robotized characteristics of an unmanned aerial vehicle with the use of 3D technologies. Some basic conclusions on the strategy development for farm production mod-ernization at a new scientific and technical level have been formulated as well.
