摘要：Parameters defining posture defects are computed based on the spatial location of selected anatomical points of the human body,which include the elements of the osseous system transferred on the body surface using the palpation method. Thus,the very nature of measured points deteriorates the accuracy of posture rating parameters. Meanwhile,present measurement methods, including photogrammetric ones,allow obtaining the measurement accuracy highly exceeding that of measurement points marking. The research method described in this paper is based on an assumption that the shape of the body surface reflects the position of the osseous elements,which are significant for the posture disorder analysis. Therefore,one can find the necessary points by analysing the said surface. The model of the human body surface was acquired using PI3000close-range photogrammetry system by Topcon,with the accuracy of measured points of 1mm. Images used as an input for the PI3000 system were acquired by two digital cameras as convergent pairs. Afterwards,the model was analysed using GeoMedia Professional with Grid extension and Idrisi Andes software. The trace of the spine was determined using DEM analysis used for water flow detection,assuming the comparability of back surface near the spine to the river valley. When determining the posture disorders,the anatomical points which are most often used for the determination of the anthropometrical coordinate system are as follows: the C7 spinous process and the posterior superior iliac spine. Attempts at detecting them were performed initially by determining the spine line (GeoMedia),then by using the surface curvature (Idrisi Andes). During the second phase of detection it turned out that it was necessary to smooth the surface model,and that it was an indispensable condition for the correct classification of height forms.
