Engineering curved surface offset method, device, equipment and vehicle

Abstract

The invention discloses an engineering curved surface offset method and device, electronic equipment and a vehicle. The method comprises the following steps: acquiring an early-stage outer surface digital-analog CAS of an engineering curved surface; performing normalization processing on the scattered surfaces in the CAS to synthesize a surface A0; determining an offset direction according to the area S0 of the surface A0; discretizing the surface A0 to obtain a plurality of single curved surfaces; grouping the plurality of single curved surfaces according to the minimum curvature of the single curved surfaces; respectively carrying out offset processing on each group according to the type of the curved surface; determining a segmentation direction based on the reference features and segmenting the curved surface; and self-adaptive chamfering and filling are carried out according to preset engineering requirements, so that a curved surface after offset is obtained. According to the method, the curved surface of the complex engineering curved surface model is classified by using an intelligent planning method, the complexity of the defect curved surface is reduced from the source based on the curved surface features, and a complete curved surface meeting the requirement can be obtained under the condition of no user interaction, so that the complex curved surface can be better biased.
