AI Technical Summary

Problems solved by technology

[0003] In the processing technology of 3D printing automobile modeling concept model, wherein the image / sketch-based model three-dimensional reconstruction, the traditional method is based on the feature information of the model image, manually extracting the model characteristic curve, according to the corresponding relationship between the curve and the image in different views, Adjust the position of the curve to obtain the space curve model of the model, and then generate a three-dimensional surface model. This method requires repeated operations of points, lines, and surfaces, and the model cannot be reused
