Final Project
Photo-podoscope
A photo-podoscope is a tool for assessing a footprint; it is performed by observing the supporting areas of the foot in standing position analized through image processing technics. This evaluation and diagnosis generally is made by a specialist like physiotherapist. Generally, this evaluation is made based on the form of the footprint by using a traditional podoscope or rudimentary process which carries several disadvantages [1]This project intends to develop a affordable photo-podoscope with image processing software to help physician to prescribe insoles.
My first sketch
Although one may assume that the final project is still 18 weeks away, there is a need to start on the planning and documentation on this. For my final project I propose a 3D foot scanner for 3D printing insoles. This device will consist of three main parts as it can be seen on the following sketch.
- 360° camera mount for photogrammetry
- Foot plantar pressure scanner
- Alignment laser
My second sketch
For my Week 2 assignment I created a second sketch which has a major change on the camera mount for photogrammetry. The new idea will have two cameras in parallel to move along the x-axis. This design was created in a raster app and a 3D render
Medical Imaging
An interesting idea would be to create a 3D model based on an Magnetic Resonance Imaging (MRI) or Computarized Tomography (CT) Both of this medical imaging proceedures are great to look at anatomical structures of a patient like bones, muscles, organs and even the overall body. For my week 5 assignment I decided to take a look at CT as a Photogrammetry alternative for a niche sector.
To use a CT scan, I used 3D Slicer, a free, open source software for visualization, processing, segmentation, registration, and analysis of medical, biomedical, and other 3D images and meshes; and planning and navigating image-guided procedures.
This recnology could also be used to create 3D printed insoles based on medical imaging in case a patient already has a CT, MRI or other medical imaging.
To have the 3D printed insole take a anatomical figure, it could be heated with a gun until the structure is moldable and the it was pressed against the patient to modify it and give it an anatomical structure.
Mobile Gait analysis device
Gait analysis helps in understanding human movement patterns and identifying abnormalities or inefficiencies in walking and running mechanics. By examining the biomechanics of an individual's gait, healthcare professionals can diagnose musculoskeletal issues, neurological disorders, or injuries affecting mobility. This analysis provides insights for designing personalized rehabilitation programs, orthotic interventions, or surgical procedures tailored to enhance mobility, alleviate pain, and improve overall quality of life.
My idea is to implement a camera that could track a person and move along their walk in a controlled environment to obtain video of their gait and provide healthcare professionals valuable information for diagnosis. This device would support a kinect camera to provide the software a reference skeleton to track and analyse the gait.
