Birds damage not only farms, orchards, fish farms, airports but also industrial and urban environments. Common methods for preventing bird damage include the use of scarecrows, the use of chemicals, and the use of nets. The method of scarecrows is not effective because of the fast adaptation of birds, the method of chemicals is effective only in small areas, and the method of nets is expensive.
In recent years, there have been many studies using sound waves, ultrasound and laser for bird repelling. The sonic method is difficult to prevent the adaption of birds, and the ultrasonic method has a small prevention area. Since the automatic laser bird repeller repeats illuminating the laser beam along a certain trajectory at regular intervals regardless of the presence or absence of birds, it is difficult to repel birds as soon as they appear in a certain position.
Pyon Su Bong, a section head at the Faculty of Metal Engineering, has developed a laser bird repellent system for scaring birds away as soon as they settle in the area under observation by a camera.
The object classification technique using the Caffe framework detects the bird in real-time captured images of a PTZ camera over a large area, and when a bird settles on an object in the area, the PTZ camera equipped with the laser beam generator is steered to the target bird, thereby scaring the bird away by attacking it by the laser beam.
