近年来，人们提出了几种高帧率捕获运动物体三维形状的方法。一种很有前途的重建三维形状的方法是投射结构光模式的投影-摄像系统。这种方法存在的一个问题是，由于纹理受到投影仪照明的干扰，难以同时获得纹理。本文提出的系统通过分离纹理和形状的光波长来克服这一问题。图案是用红外光投射的，纹理是用可见光捕捉的。如果用于红外和可见光的摄像机放置在不同的位置，会导致纹理和形状的不对齐，从而降低纹理3D模型的质量。因此，我们开发了一种多波段相机，可以从单一视点获取可见光和红外光。此外，为了利用多波长的光，即多颜色重建三维形状，开发了一种红外图案投影仪来生成多波段网格图案。此外，还提出了一种使用固定网格模式对系统进行标定的简单方法。最后，我们展示了实验系统捕获的纹理三维形状。
Recently, several method have been proposed to capture 3D shapes of a moving object at a high frame rate. One of promising approach to reconstruct a 3D shape is a projector-camera system that projects structured light pattern. One of the problem of this approach is that it has difficulty to obtain texture simultaneously because the texture is interfered by the illumination from the projector. The system proposed in this paper overcomes this issue by separating the light wavelength for texture and shape. The pattern is projected by using infrared light and the texture is captured by using visible light. If the cameras for infrared and visible lights are placed at different position, it causes the misalignment between texture and shape, which degrades the quality of the textured 3D model. Therefore, we developed a multi-band camera that acquires both visible and infrared lights from a single viewpoint. Moreover, to reconstruct a 3D shape using multiple wavelengths of light, namely multiple colors, an infrared pattern projector is developed to generate a multi-band grid pattern. Additionally, a simple method to calibrate the system is proposed by using a fixed grid pattern. Finally, we show the textured 3D shapes captured by the experimental system.
