3D Model of Photogrammetry Technique for Transtibial Prosthetic Socket Design Development

This paper presents the development of the manufacture of a transtibial prosthetics socket for the below-knee amputee. A technique used in this paper is using photogrammetry. The quality of the photogrammetry method is determined by measuring the error of the photogrammetry 3D model with the actual model using four different cameras. The 3D model of the transtibial socket is created by taking photos of the remaining limb of the amputee and process it in the software for the 3D generation and rectification process. 3D printing is needed to print the 3D model of the socket and then compare it to the conventional casting socket using image processing. The test will be conducted by applying the 3D printed socket to the amputee to be used for a walk.
