Abstract：Base curve is the quantitative indicator of horizontal bending of goggles.Some parameters necessary for the calculation of goggles′ base curve cannot be manually measured.To address this issue, a computer-aided measurement system was proposed for measuring parameters necessary for the calculation of goggles′ base curve in this paper.This system consisted of three main modules: the module of medical image preprocessing and construction of volume data set, the module of rendering and display of volume data and the module of measurement of parameters necessary for the calculation of goggles′ base curve.According to the different characteristics of medical images, parameters necessary for the calculation of goggles′ base curve were measured from 2D image or 3D volume model.(The parameters directly from image when the image was symmetric was measured by the system.) In case of asymmetry, the parameters were measured on a symmetric contour extracted from 3D body model.The experimental results demonstrate that this computer-aided system is capable to measure parameters necessary for the calculation of goggles'' base curve accurately and meets the need of application.
