The Measurement Method of Light Distribution Emitted from Sports Facilities Using Unmanned Aerial Vehicles

The dynamic development of cities is associated with a significant increase in the luminance of architectural buildings, advertisements or usable spaces. Objects that emit a significant amount of luminous flux to the environment are also various types of sports buildings, such as city stadiums, football pitches or tennis courts. The need to protect the environment determinates the need to reduce and prevent the effect of light pollution. The article analyzes the possibilities of using unmanned aerial vehicles to assess light pollution by measuring the distribution of luminous flux emitted by sports facilities. The method of light measurement based on a goniometric system using unmanned aerial vehicles was presented and their positioning in three-dimensional space was taken into account. A method for controlling the photometric probe and calibrating the measurement system has been proposed.
