Figure 7
Evaluation of postural defect using photogrammetric method. The patient has markers (arranged by the expert) in specific points on the skin. On the basis of two images at different angles (stereovision), three-dimensional reconstruction of the position of the markers is carried out. The shadows, arising from improper lighting, generate shadows and errors in the analysis. The points marked in Figure a) in red are in front of the patient while the ones in green are a reflection in the mirror. In Figure b) the colours indicate the results of the correct operation of the algorithm for image analysis and processing involving identification (with successive colours) of the group of points assigned to specific organs.
