ANALYSIS OF FACTORS INFLUENCING THE EFFICIENCY OF USING TECHNOLOGIES FOR DIGITAL RECORDING OF GAME ANIMALS

Conducting aerial surveys of hunting farms using unmanned aerial vehicles showed that in the process of deciphering photographs, a number of problems arise related to the unambiguous identification of accounting objects. The aim of the work is to determine the limiting factors for the use of infrared and photography to account for game animals. The object of the study is the data of photography and thermal imaging in the winter and autumn periods of the forests of the Tisulsky and Krapivinsky districts of the Kemerovo region - Kuzbass. To account for animals, the author's concept of the study was used using a combination of conventional photo and video shooting and thermal imaging in the infrared spectrum. When processing the results of digital shooting of game animals, data were obtained that allow us to speak about some regularities in the influence of environmental factors. With a comparable number of images with identified heat signatures in the same area, the proportions between the total number of potential objects of accounting, the shares of images with automatically and manually identified game animals, and the proportions of unidentified heat signatures differ significantly in winter and autumn. A comparison of survey results in winter and autumn shows that winter accounting is more accurate and less laborious, while autumn accounting can be used as needed, but involves higher costs and errors. The features of the application of digital technologies for accounting for game animals are determined. It has been established that the results of digital survey are influenced by several most important environmental parameters - the season (and the condition of the vegetation cover associated with it, the temperature of various surfaces), the time of day, weather conditions, and the presence of anthropogenic thermal radiation.
