Abstract

Because of the fast take-off speed of badminton, a single action recognition method can’t quickly and accurately identify the action. Therefore, a new badminton take-off recognition method based on improved deep learning is proposed to capture badminton take-off accurately. Collect badminton sports videos and get images of athletes’ activity areas by tracking the moving targets in badminton competition videos. The static characteristics of badminton players’ take-off actions are extracted from the athletes’ activity areas’ images using 3D ConvNets. According to the human joint points in the badminton player’s target tracking image, the human skeleton sequence is constructed by using a 2D coordinate pseudo-image and 2D skeleton data design algorithm, and the dynamic characteristics of badminton take-off action are extracted from the human skeleton sequence by using LSTM (Long-term and Short-term Memory Network). After the static and dynamic features are fused by weighted summation, badminton take-off feature fusion results are input into a convolutional neural network (CNN) to complete badminton take-off recognition. The CNN pool layer is improved by adaptive pooling, and the network convergence is accelerated by combining batch normalization to further optimize the recognition results of badminton take-off. Experiments show that the human skeleton model can accurately match human movements and assist in extracting action features. The improved CNN has greatly improved the accuracy of recognition of take-off actions. When recognizing real images, it can accurately identify human movements and judge whether there is a take-off action.

基于改进型深度学习的羽毛球起飞识别方法研究
由于羽毛球起飞速度快,单一的动作识别方法无法快速准确地识别动作。因此,提出了一种基于改进的深度学习的新型羽毛球起飞识别方法,以准确捕捉羽毛球的起飞动作。采集羽毛球运动视频,通过跟踪羽毛球比赛视频中的运动目标,获取运动员活动区域图像。利用三维 ConvNets 从运动员活动区域图像中提取羽毛球运动员腾空动作的静态特征。根据羽毛球运动员目标跟踪图像中的人体关节点,利用二维坐标伪图像和二维骨架数据设计算法构建人体骨架序列,并利用 LSTM(长短期记忆网络)从人体骨架序列中提取羽毛球运动员起跳动作的动态特征。通过加权求和将静态和动态特征融合后,将羽毛球腾空特征融合结果输入卷积神经网络(CNN),完成羽毛球腾空识别。通过自适应池化改进 CNN 池层,并结合批量归一化加速网络收敛,进一步优化羽毛球起飞的识别结果。实验表明,人体骨架模型能准确匹配人体动作,并辅助提取动作特征。改进后的 CNN 极大地提高了起飞动作的识别准确率。在识别真实图像时,它能准确识别人体动作并判断是否有起球动作。
