With the development of computer technology, information technology, and 3D reconstruction technology of the medical human body, 3D virtual digital human body technology for human health has been widely used in various fields of medicine, especially in teaching students of application and anatomy. Its advantage is that it can view 3D human anatomy models from any angle and can be cut in any direction. In this paper, we propose an improved algorithm based on a hybrid density network and an element-level attention mechanism. The hybrid density network is used to generate feasible hypotheses for multiple 3D poses, solve the ambiguity problem in pose reasoning from 2D to 3D, and improve the performance of the network by adding the AReLU function combined with an element-wise attention mechanism. Teaching students in anatomy makes students' learning more convenient and teachers' teaching explanations more vivid. Comparative experiments show that the accuracy of 3D human pose estimation using a single image input is better than the other two-stage methods.
随着计算机技术、信息技术和医学人体 3D 重建技术的发展,3D 虚拟数字人体技术在医学的各个领域得到了广泛的应用,特别是在医学生应用解剖学的教学中。它的优点是可以从任何角度观察 3D 人体解剖模型,并可以沿任何方向进行切割。本文提出了一种基于混合密度网络和元素级注意力机制的改进算法。混合密度网络用于为多个 3D 姿势生成可行假设,解决从 2D 到 3D 的姿势推理中的歧义问题,并通过添加与元素级注意力机制相结合的 AReLU 函数来提高网络的性能。在解剖学教学中,该技术可以使学生的学习更加方便,教师的教学讲解更加生动。对比实验表明,使用单图像输入进行 3D 人体姿势估计的准确性优于其他两种两阶段方法。
