Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and the benefit of Korean Patent Application No. 10-2022-0102250 filed in the Korean Intellectual Property Office on Aug. 16, 2022, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to image processing using a computing device, and particularly, to a method, a computer program, and a device for identifying a hit location of a dart pin. BACKGROUND ART In general, a dart means a “little arrow” and is a game of throwing arrow-shaped darts at a centrifugal target labeled with numbers to score points. The dart game has the advantage that anyone can play at any time when arrowhead-shaped darts and a dart game apparatus are provided. In recent years, the dart game has developed into a global leisure activity with the development of various competition methods and the organization of scoring methods, and people of all ages easily enjoy the game. A dart game apparatus may identify a hit location of a dart pin hitting on a dart target by analyzing an image sensed by a sensor installed on the dart target or an image taken of the dart target. The image analysis method need to process images taken from cameras at various locations. The image analysis method that use rule-based algorithms has a problem in that it is difficult to secure accuracy due to noise, because dart game apparatuses are in various installation environments. The image analysis method based on deep learning has the problem, such as the difficulty of securing a large enough dataset and implementing algorithms to process the hit locations of multiple dart pins.
