This is not optimal when geometry is updated and needs to be visualized without closing the window. My code is able to recognize the RGB values, when it is either 255 or 0, any value between 1 and 254, the code is not recognizing and the dots have no associated color. The main function runs local_refinement and optimize_posegraph_for_scene. (Park et al. In order to demonstrate the alignment between colored point clouds, draw_registration_result_original_color renders point clouds with their original color. In [config], ["path_dataset"] should have subfolders fragments which stores fragments in . 16. Enum class for Geometry types. Multiway registration is the process to align multiple pieces of geometry in a global space.
