Web16 aug. 2024 · Depth image and color image alignment algorithm. RGB-D cameras generally have two physical sensors: the infrared sensor that captures the depth image and the RGB sensor that captures the color image. Each sensor has its own two-dimensional pixel planar coordinate system and three-dimensional point cloud coordinate system. WebImage alignment consists of moving, and possibly deforming, a template to minimize the differ-ence between the template and an image. Since the ﬁrst use of image alignment in the Lucas-Kanade optical ﬂow algorithm [11], image alignment has become one of the most widely used techniques in computer vision.
