本研究的目的是开发一种创新的近距离数字摄影测量 (CRDP) 系统，使用商用数码单反相机来测量和重建假肢和矫形器的 3D 表面。本文描述了所提出系统的仪器、技术和初步结果。该技术的工作原理是从多个视角拍摄物体的照片。这一系列图片通过特征点提取、点匹配和3D表面重建进行后处理。与激光扫描等传统方法相比，我们的仪器的主要优点包括成本较低、硬件紧凑且易于使用、测量精度令人满意、测量时间显着缩短。除了在假肢和矫形器表面测量中的潜在应用之外，简单的设置和易用性也使其适用于各种 3D 表面重建。
The objective of this study is to develop an innovative close range digital photogrammetry (CRDP) system using the commercial digital SLR cameras to measure and reconstruct the 3D surface of prosthetics and orthotics. This paper describes the instrumentation, techniques and preliminary results of the proposed system. The technique works by taking pictures of the object from multiple view angles. The series of pictures were post-processed via feature point extraction, point match and 3D surface reconstruction. In comparison with the traditional method such as laser scanning, the major advantages of our instrument include the lower cost, compact and easy-to-use hardware, satisfactory measurement accuracy, and significantly less measurement time. Besides its potential applications in prosthetics and orthotics surface measurement, the simple setup and its ease of use will make it suitable for various 3D surface reconstructions.
