Three-dimensional laser scanning point cloud precision analysis method and system

The invention discloses a three-dimensional laser scanning point cloud precision analysis method and system, and relates to the technical field of three-dimensional laser scanning, and the system comprises a data collection module, a data processing and management module, a precision evaluation and analysis module, an evaluation report generation module, and a comparison adjustment module. The technical key points are as follows: the processing efficiency is remarkably improved through automatic data preprocessing, registration and model reconstruction processes, the requirement of manual intervention is reduced, and efficient data processing is realized through automatic filtering and denoising, automatic registration algorithm adjustment and three-dimensional model construction; a complex industrial scene can be quickly and accurately digitalized and analyzed; by feeding back the quality problem of the model in real time and taking measures immediately when the quality does not reach the standard, the risks
