A vision-based non-contact area and volume estimation of irregular structures towards applications in wound measurement

Abstract

Area and volume computation of irregular structures can be done using several techniques, but accuracy and the speed of computation is become an issue. But when wounds are considered for measurements, another factor comes into picture which is the risk of contamination due to direct contact with wounds and this can lead to catastrophic situations. In order to combat such issues, there is a requirement of non-contact measurement technique and thus, the paper discusses about a vision-based non-contact method for area and volume computation of irregular structures. The methodology presented here, models the irregular structured object using Delaunay triangulation and thus computes area and volume from the model formed. The new method is experimented on certain regular and irregular shaped objects and the results obtained along with their accuracy are provided.
