以三维影像技术进行人面影像鉴定初探

Primary Discussion on Face Identification by Three-Dimensional Image Technology

本文阐述了三维相位探测相机系统的原理以及运用该系统辅助进行人面影像鉴定的方法。文中详述了对人面影像特征点、特征线的标画方法,以及运用设定的特征线作为参考进行调整三维人面影像的角度和大小,然后与平面人面影像进行重叠比对的方法。本文引用外眼点间距为100mm作为标准调整人面大小,并由此解决了不同人面部大小不同而无法统一鉴定标准的难题。

By describing the principle of survey camera and its application for face identification,methods explained on characteristics of face image and specific lines,usage explained on adjusting angle and size of face image by specific lines,including compilation on flat face overlapping;problems solved by applying loomm eye outside distance as a standard to make proper adjustment.
