Inteligentny pojazd dla osób chorych, niepełnosprawnych i seniorów

tom z. 4/85

91--100

W artykule została przedstawiona propozycja projektu inteligentnych pojazdów wspomagających poruszanie się pacjentów szpitali, osób starszych i niepełnosprawnych. Pojazd tego typu, poza przemyślaną konstrukcją mechaniczną, dostosowanym napędem i dodatkowym osprzętem, musi charakteryzować się pewną formą inteligencji umożliwiającej automatyczne wytyczanie tras, rozpoznawanie obiektów oraz dostosowywanie się do nowych uwarunkowań. Realizacja tego typu projektu jest możliwa tylko w interdyscyplinarnym zespole skupiającym ekspertów z dziedzin takich jak mechanika, elektronika i informatyka.

In this article proposal of intelligent vehicle supporting locomotion of hospital’s patients, the elderly and handicapped people was presented. The vehicle of this type, in addition to well thought mechanical construction, customized drive and additional equipment must be characterized by some form of intelligence that allows to find paths, object recognition and adaptation to new conditions. The implementation of this type of project is possible only in an interdisciplinary team brings together experts from fields such as mechanics, electronics and computer science.

In this paper a new method of automatic image segmentation is presented. In proposed approach a region merging method is applied, where pixels or pixel groups are merged to bigger areas. In the proposed method of the region merging seed settings, segmentation parameter definition, and number of outcome areas determining can be omitted. Homogeneous clusters (consisting of continuous groups of pixels) are the part of the growth process. The clusters are merged when the homogeneousness condition is fulfilled. The threshold value changes during segmentation process, appropriate to the changeable conditions.

At present, in mandibular fractures surgical treatment reposition and titanium miniplates osteosynthesis is the most common method used. The treatment results are assessed on the basis of comparative analysis of two radiograms taken before and after fixations of fractures. In this article the objective method of radiological assessment of osteosynthesis is presented. The crucial part of the method is the computer program which was created at The Institute of Computer Biomedical Systems, Silesian University in Katowice. Comparison of placement of bone fragments on a pair of pantomograms taken before and after a particular surgical operation was done. To make the process of the results evaluation an objective one a new parameter - the relative dislocation coefficient - was implemented. Achieved results enable to assess correctness of bone fracture reposition on the pantomographical pictures taken twice, once before and the next time after osteosynthesis.

The method of objective assessment of the correctness mandible bones fracture slit was proposed in the research. At present, treatment results are evaluated by comparing pantomographic pictures made before and after integration. It is not an objective method; the estimation of the integration correctness coefficient is not possible, either. The use of computer processing enables introducing the relative mandible faction dislocation coefficient. Thanks to this, measurable determination of bone faction reposition correctness on pantomograms made after osteosynthesis is possible.
