Embodiment
[0042] Explore the logical correspondence matrix Ω between the corresponding depth and the color image, specifically including:
[0043] 1) Sampling the corresponding depth and color images
[0044] Using the common sampling algorithm for the corresponding depth image Y 1 and color image Y 2 Sampling is performed separately to obtain the depth sample X 1 , color sample X 2 .
[0045] 2) Clustering depth samples
[0046] Since the present invention considers the depth and color images as a whole, after the sampling is completed, the depth and color samples are combined to obtain the overall sample X, namely According to the characteristics of the depth image, points on the same plane in the scene have the same depth information, it can be known that only a small amount of depth information in the sample can extract the features of the image. Therefore, according to the depth information in the overall sample, the general clustering algorithm (such as the K-Means algorith...
