Description

technical field [0001] In the field of information technology, the present invention specifically relates to a method and system for dynamically displaying massive point clouds based on real colors. Background technique [0002] Ancient buildings refer to civil buildings and public buildings with historical significance before the founding of the People's Republic of China. In China, many ancient towns and most big cities still retain some ancient buildings. However, in the current era of large-scale construction projects, coupled with the influence of uncontrollable factors such as natural wind and rain, fire, etc., a large number of ancient buildings with historical and cultural significance have disappeared from people's vision. In many cases, ancient buildings can only be restored or repaired to a certain extent by relying on the interpretation of historians and the understanding of construction engineers. [0003] The method of 3D scanning ancient buildings in the pri...
