摘要： 为了快速、有效地对三维物体的表面进行重建，提出了一种基于深度和颜色的3D表面重建方法。该方法利用同一物体在空间稀疏分布的不同视点下的多幅深度图像，根据3D物体表面同一点在不同深度图像上颜色和纹理的一致性，通过逆投影变换，可将图像中像素点映射到三维空间中的正确位置。然后在以物体为中心的单个坐标系下，进行数据融合，可得到三维物体表面各点的三维数据。实验结果表明该方法具有复杂度恒定、获取图像真实感强等优点，适用于形状、结构复杂的物体重建。

Abstract: In order to reconstruct three dimension model of a solid, a new method based on the color and texture of image is presented. This method uses sereval range image of different viewpoint, according to the color and texture, the pixel point can be mapped to correct position in three dimension space by the backproject transformation. Then the image can be got in any viewpoint by modeling reconstruction and reproject. Experiments have proved that this method can acquire high realistic image and has static complexition. It can be used for modeling reconstruction of any shape solid.
