초록

레이더나 라이더 센서를 활용한 야구 경기 분석은 많은 비용이 요구된다. 본 논문에서는 중계 비디오에서 피치 샷과 타구 샷을 검출하고, 카메라의 움직임 기반 타구 궤적 생성 알고리즘을 제안한다. 제안하는 알고리즘은 객체 검출과 옵티컬 플로우 기반 피치 샷과 타구 샷 검출 이후, 프레임 간 변환 관계를 통해 프레임 내 타구 위치와 타구 궤적을 계산한다. 제안 방법은 KBO 중계 영상 시퀀스 3개에 대해 성능을 평가하였고 피치 샷과 타구 샷 검출 정확도와 검출률은 89-95[%] 이내의 성능을 보였으며, 평균 타구 위치 거리차이는 13.6[m], 방향 차이 7.5°, 파울 분류 정확도 98.6%의 성능을 보였다.

Analyzing baseball games using sensors such as radars or riders is expensive. In this paper, we propose an algorithm to detect pitch shots and hit shots using baseball video and to generate ball trajectories within hit shots using camera movement. After the pitch shot and the hit shot detection using object detection and optical flow, we generate the transformation relationship between frames and ball locations in the frame, and calculates the ball trajectory. The performance of the proposed method is evaluated for three KBO baseball video sequences, and the detection accuracy and detection rate of pitch shot and hit shot were within 89-95 [%], and the average error for shot range was 13.6[m], The direction error was 7.5° and foul classification accuracy was 98.6%.
