The present invention relates to a method and a system for observing a bidirectional reflectance distribution function using a drone. A method for observing a bidirectional reflectance distribution function using a drone according to an embodiment of the present invention is a computer implemented method for bidirectional reflectance distribution function observation executed on a computing device, and comprises: a first step of setting a flight path so that a drone equipped with a spectral sensor is flying on a spherical path to observe an object; a second step of determining a direction in which the spectral sensor is looking, and measuring a reflected radiation by the spectral sensor; and a third step of calculating a bidirectional reflectance distribution function (BRDF) by using the direction in which the spectral sensor is looking. Bidirectional reflectance distribution function (BRDF) can be measured for hard-to-reach objects.
