Ultra-compact type air inlet channel molded surface aided design method and system

The invention belongs to the technical field of air inlet channel structural design, and discloses an ultra-compact type air inlet channel molded surface aided design method and system. According to the method, the generation of discrete information of the integral structure of the air inlet and the display of various key geometric characteristic curve graphs and part of geometric characteristic parameter values can be realized by importing the user-defined model file containing various parameter values of the air inlet or editing and inputting various parameter values of the air inlet; meanwhile, simple dynamic display of an air inlet three-dimensional model with an auxiliary observation function and generation of a point cloud coordinate file can be quickly realized, and on this basis, aiming at spatial structure characteristics of point cloud coordinates, a specific triangular meshing method without point cloud denoising is realized, and a three-dimensional file containing triangular mesh information is ge
