A scheme for texture mapping a 3D individualized color photo-realistic facial model from real color portraits and CT data is described. First, 3D CT images including both soft and hard tissues should be reconstructed from sequential CT slices, using a surface rendering technique. Facial features are extracted from 3D soft tissue. A generic mesh is individualized by correspondence matching and interpolation from those feature vertices. Three digitized color portraits with the "third" dimension from reconstructed soft tissue are blended and texture-mapped onto the 3D head model (mesh). A color simulated human head generated from frontal, right and left real color portraits can be viewed from an arbitrary angle in an inexpensive and user-friendly conventional personal computer. This scheme is the basic procedure in 3D computer-assisted simulation surgery.
描述了一种从真实彩色肖像和CT数据对3D个性化彩色逼真面部模型进行纹理映射的方案。首先，应使用表面渲染技术从连续的CT切片重建包括软组织和硬组织的3D CT图像。从3D软组织中提取面部特征。通过从这些特征顶点进行对应匹配和插值，将通用网格个性化。将具有来自重建软组织的“第三”维度的三张数字化彩色肖像进行混合，并纹理映射到3D头部模型（网格）上。可以在廉价且用户友好的传统个人计算机上从任意角度查看由正面、右侧和左侧真实彩色肖像生成的彩色模拟人头。该方案是3D计算机辅助模拟手术的基本步骤。
