    • An image processing method and apparatus includes selecting a first pixel group including at least one pixel from an input color image; selecting a second pixel group including at least one pixel corresponding to each of the at least one pixel included in the first pixel group from an input depth image; calculating a transformation function of the first pixel group and second pixel group based on a coordinate value of each of the at least one pixel included in the first pixel group and a coordinate value of each of the at least one pixel included in the second pixel group; and matching each pixel of the input color image with each pixel of the input depth image based on the transformation function.
    • 一种图像处理方法和装置,包括从输入彩色图像中选择包括至少一个像素的第一像素组; 从输入深度图像中选择包括与包括在所述第一像素组中的所述至少一个像素中的每一个对应的至少一个像素的第二像素组; 基于包括在第一像素组中的至少一个像素中的每一个的坐标值和包括在第二像素组中的至少一个像素中的每一个的坐标值来计算第一像素组和第二像素组的变换函数 ; 并且基于变换函数将输入彩色图像的每个像素与输入深度图像的每个像素匹配。

    • A method and apparatus for matching images are provided. The image matching method includes: obtaining a depth image and an intensity image of an object using a depth camera installed at a first position and a color image of the object using a color camera installed at a second position other than the first position; transforming the obtained depth image and intensity image into a depth image and an intensity image, respectively, that could be obtained if the object were photographed by a camera at the second position; and matching the transformed depth image and intensity image and the obtained color image. In this way, a depth image and intensity image obtained separately from a 2-dimensional (2D) color image can be accurately matched to the 2D color image, thereby allowing a reliable 3D image to be obtained.
    • 提供了一种用于匹配图像的方法和装置。 图像匹配方法包括:使用安装在第一位置的深度相机和安装在除了第一位置之外的第二位置的彩色照相机的物体的彩色图像来获得物体的深度图像和强度图像; 将所获得的深度图像和强度图像分别转换成如果在第二位置通过照相机拍摄对象可以获得的深度图像和强度图像; 并匹配变换的深度图像和强度图像和所获得的彩色图像。 以这种方式,可以将与二维(2D)彩色图像分开获得的深度图像和强度图像精确地匹配到2D彩色图像,从而获得可靠的3D图像。
