Vision system to obtain spatial coordinates in bony protuberances of the human body through ArUco markers

Abstract

Actually, the vision systems have a great impact in technological innovation, since they represent the eyes of any device or machine, therefore the importance of this is paramount. On the other hand, in one of the branches of biomechanicsstudies are carried out to diagnose disorders in the gait cycle of patients, normally a physiotherapist performs specific exercises to determine if there is an abnormally during the gait cycle, however, the accuracy of the diagnosis can become uncertain if the physiotherapist has carried out several continuousstudies and factors such as lighting of the place or eye fatigue cause alterations in its diagnosis, therefore, with the development of this project it is intended to make a vision system that, from markers positioned on bony protrusions on the lower part of the human body, get the spatial coordinates (X, Y and Z), information that adding a post processing would allow obtaining data such as angular movements, angular velocities and custom gait cycles, fundamental data in the development of prostheses, orthoses or exoskeletons, and considering that the project is carried out in free software, its implementation becomes more accessible.
