【摘要】：基弯是护目镜水平方向弯度的量化指标。由于手工无法直接测量护目镜基弯值计算所需参数,本研究提出了基于医学图像处理的计算机辅助测量系统。该计算机辅助测量系统包括:医学图像预处理与体数据场构建、体数据绘制与显示、护目镜基弯值计算所需参数测量等功能模块。针对图像的不同特性,系统基于二维图像与三维体模型,对护目镜基弯值计算所需参数进行测量。在处理对称图像序列时,该系统直接在图像上测量;在处理不对称图像序列时,该系统基于三维体模型轮廓提取技术,在提取的对称轮廓上测量。实验结果表明:该计算机辅助测量系统能精确地测量护目镜基弯值计算所需参数,满足了应用需求。
[Abstract]:The base bend is a quantitative index of the horizontal curvature of the goggles. Because the parameters needed to calculate the base bending value of goggles can not be measured directly by hand, a computer-aided measurement system based on medical image processing is proposed in this paper. The computer aided measurement system includes: medical image preprocessing and volume data field construction, volume data rendering and display, parameter measurement required for the calculation of the base bending value of goggles, and so on. According to the different characteristics of the image, the parameters needed for the calculation of the base bending value of the goggles are measured based on the two-dimensional image and the three-dimensional volume model. In the process of processing symmetrical image sequences, the system measures directly on the image, and in the processing of asymmetric image sequences, the system measures on the extracted symmetrical contour based on the 3D volume model contour extraction technique. The experimental results show that the computer aided measurement system can accurately measure the parameters needed to calculate the base bending value of the goggles and meet the requirements of application.
