The present invention relates to a wind direction/velocity measurement apparatus for a small-sized flying object, and more particularly to a wind direction/velocity measurement apparatus for a small-sized flying object, which includes: a spherical light emitting body having an infrared ray LED therein, for emitting an infrared ray; a connecting member of a predetermined length or more connected to a lower portion of the flying object in the gravitational direction, and of which one end is connected to the flying object and of which an opposite end is connected to the light emitting body; a photographing module provided at a lower portion of the flying object, for photographing infrared images of the light emitting body connected to the connecting member; a movement information measurement module provided in the flying object, for measuring a movement direction and a movement speed of the flying object; and a wind direction/velocity estimation module for estimating a wind direction and a wind velocity of a space in which the light emitting body by using the plurality of infrared images photographed by the photographing module and the movement direction and the movement speed measured by the measurement module. According to the wind direction/velocity measuring apparatus for a small-sized flying object suggested by the present invention, a wind direction and a wind velocity can be estimated by connecting a light emitting body to one end of a connecting member connected to the small-sized flying object and photographing and analyzing infrared images of the light emitting body, and an effective wind direction and an effective wind velocity can be measured regardless of movement and stop of the flying object by minimizing an influence of air flows generated by the small-sized object as the length of a connecting member is a predetermined value or more. Further, according to the present invention, a wind direction and a wind velocity can be measured in wide ranges through a three-dimensional flight of the small-sized flying object while flying stability is maintained by connecting the connecting member connected to a distal end to the weight center of the flying object with the light emitting body. |
