In recent years, spinal disorders, spinal deformities, and scoliosis have become more frequent, especially chronic systemic inflammatory diseases, such as early-onset scoliosis, idiopathic scoliosis, and ankylosis spondylitis, which have unknown causes, insidious onset, and progressive development, resulting in irreversible spinal joint deformities and stiffness at advanced stages and high disability rates. As one of the traditional Chinese health and fitness qigong exercises, Taijiquan has the effect of strengthening the waist and kidneys, sparing the tendons and softening the body, unblocking the meridians, unblocking the qi and blood, and strengthening the body and increasing intelligence. To this end, this paper proposes a data enhancement method that uses the spine line as the control curve to deform the human contours, drawing on the moving least squares deformation method to fit a variety of scoliosis cases and increase the diversity of the dataset, thereby improving the generalisation capability of the network. The colour map and depth map information are then integrated using a four-channel method and a dual feature extraction network structure to improve the accuracy of segmentation.
近年来,脊柱疾病、脊柱畸形和脊柱侧凸越来越常见,尤其是慢性全身炎症性疾病,如早发性脊柱侧凸、特发性脊柱侧凸和强直性脊柱炎,这些疾病病因不明、隐匿起病且逐渐发展,导致晚期不可逆转的脊柱关节畸形和僵硬,致残率高。作为中国传统健身气功之一,太极拳具有强腰补肾、舒筋活络、疏通经络、气血畅通、强身健体、益智的功效。为此,本文提出了一种数据增强方法,该方法使用脊柱线作为控制曲线来变形人体轮廓,借鉴移动最小二乘变形方法来拟合各种脊柱侧凸病例,增加数据集的多样性,从而提高网络的泛化能力。然后,使用四通道方法和双特征提取网络结构将彩色图和深度图信息进行整合,以提高分割的准确性。
