The majority of existing real-time 3D shape measurement systems only generate non-nature texture (i.e., having illumination other than ambient lights) that induces shadow related issues. This paper presents a method that can simultaneously capture natural 2D color texture and 3D shape in real time. Specifically, we use an infrared fringe projection system to acquire 3D shapes, and a secondary color camera to simultaneously capture 2D color images of the object. Finally, we develop a flexible and simple calibration technique to determine the mapping between the 2D color image and the 3D geometry. Experimental results demonstrate the success of the proposed technique.
现有的大多数实时三维形状测量系统仅生成会引发阴影相关问题的非自然纹理（即具有环境光以外的光照）。本文提出了一种能够实时同时捕捉自然二维彩色纹理和三维形状的方法。具体而言，我们使用红外条纹投影系统来获取三维形状，并使用一台辅助彩色相机同时捕捉物体的二维彩色图像。最后，我们开发了一种灵活且简单的校准技术，以确定二维彩色图像与三维几何之间的映射关系。实验结果证明了所提技术的成功。
