本文提出了一种基于距离图像和彩色（或强度）图像的配准方法。在距离强度图像和彩色图像之间引入梯度约束，推导出配准参数的线性方程，该方程结合了内外参数的位移估计。通过使用该方程，精确的自动配准无需显式检测的对应关系。实验结果验证了该方法的有效性。
This paper proposes a method for the registration of range and color (or intensity) images, based on the range intensity image that is simultaneously acquired with a range image. The gradient constraint between the range intensity image and the color image is introduced, and a linear equation for the registration parameters is derived, which combines displacement estimations for extrinsic and intrinsic parameters. By using the equation, precise automatic registration without explicit detection of correspondences is achieved. Experimental results illustrate the proposed method.
