医用植入体的多视立体三维重建

Multi-view Stereo 3D Reconstruction of Medical Implants

为了方便医生在介入治疗手术中从三维角度更加全面地获取信息和准确操作,该文采用了多视角立体重建算法对医用植入体进行了体外三维重建,从拍摄方法和环境条件等角度分析了重建时间和效果的影响,并利用便捷的拍摄设备和开源软件对支架进行了多视角图像的采集和点云数据的获取,交互式地运用逆向工程软件对点云进行精细化处理和表面生成,最终重建出了可用于工业生产的植入体三维模型。

In order to facilitate the doctor to obtain information more comprehensively and operate accurately from a three- dimensional perspective in interventional therapy, the paper uses a multi-view stereo reconstruction algorithm for three-dimensional reconstruction of medical implants in vitro. The effects of shooting and environmental conditions on reconstruction time and effect were analyzed. We use the convenient shooting device to collect multi-view images of the stent and open source software to acquire the point cloud data. By using reverse engineering software, the point cloud is processed interactively and the surface is generated. Eventually, the 3D model of the implant is reconstructed, which can be used for industrial production.
