[0055] The embodiment of the present invention provides a method for generating a side design surface model, referring to Figure 2 , Figure 2 It is a schematic flow chart of the first embodiment of the method for generating a side panel design surface model of the present invention.

[0056] In this embodiment, the side panel design surface model generation method includes the following steps:

[0057] Step S10: determining the surface data and line data to be updated according to the side design surface and the preset surface model.

[0058] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a side panel design surface model generation device, etc. The following takes the side panel design surface model generation device (referred to as the model generation device) as an example to illustrate this embodiment and the following embodiments.

[0059] It can be understood that the side panel design surface can be a design surface corresponding to the vehicle body stop, and the vehicle body stop includes the front door stop, the rear door stop, etc. The present embodiment is illustrated by taking the side panel design surface corresponding to the front door stop as an example; the preset surface model can be a pre-constructed side panel design surface model corresponding to the front door stop. If the data of the front door stop changes, the side panel design surface model corresponding to the changed front door stop can be obtained by replacing the corresponding data in the preset surface model.

[0060] It should be understood that the surface data to be updated may be data of changes in the side panel design surface relative to the model surface in the preset surface model; the line data to be updated may be data of changes in the side panel design surface relative to the model line in the preset surface model.

[0061] In a specific implementation, the model generation device obtains the design surface data of the side panel design surface and the model data of the preset surface model, and determines the surface data and line data of the side panel design surface that have changed relative to the preset surface model based on the design surface data and the model data.

[0062] Step S20: updating the corresponding model surface data in the preset surface model according to the surface data to be updated to obtain a surface replacement model.

[0063] It can be understood that the surface replacement model can be a model obtained by replacing the data of the model surface that has changed in the preset surface model with the surface data to be updated.

[0064] Step S30: updating the corresponding stop line data in the surface replacement model according to the line data to be updated, and obtaining a side panel design surface model corresponding to the side panel design surface.

[0065] In this embodiment, the corresponding model surface data in the preset surface model is first replaced according to the surface data to be updated to obtain a surface replacement model, and then the corresponding stop line data in the surface replacement model is replaced according to the line data to be updated to obtain a side panel design surface model corresponding to the side panel design surface.

[0066] In a specific implementation, a preset surface model N is constructed according to the side panel design surface M1 corresponding to the front door stop M. The preset surface model can be referred to Figure 3 , Figure 3 The schematic diagram of the preset surface model constructed according to the side design surface corresponding to the front door stop, assuming that the side design surface M1 corresponding to the front door stop needs to be modified, the modified content is the B-pillar design surface FS04 and the angular surfaces FS08 and FS09 corresponding to FS04, and the angular end lines FC08 and FC09 corresponding to FS04, and the modified side design surface is set to M2, then the surface data to be updated and the line data to be updated are determined according to the data difference between M2 and B, and the corresponding model surface data in the preset surface model is first updated according to the surface data to be updated to replace the corresponding model surface data in the preset surface model. The surface FS04, FS08 and FS09 are used to obtain the surface replacement model, and then the corresponding stop line data in the surface replacement model is updated according to the line data to be updated to replace the corresponding stop lines FC08 and FC09 in the preset surface model, so as to obtain the side panel design surface model corresponding to the modified side panel design surface, and complete the construction of the new model. Assuming that the side panel design surface still needs to be modified later, the corresponding model surface data and stop line data can be replaced based on the preset surface model, or can be replaced based on the side panel design surface model, which can be determined according to the actual situation, and this embodiment is not limited here.

[0067] Furthermore, in order to determine the surface data and line data to be updated, the step S10 includes: comparing the side design surface with the preset surface model; determining difference data according to the comparison result, and determining the surface data and line data to be updated according to the difference data.

[0068] It can be understood that comparing the side panel design surface with the preset surface model can be comparing the data of the side panel design surface with the data of the preset surface model to determine the difference data between the side panel design surface and the preset surface model; the difference data can be the data of the side panel design surface changed relative to the preset surface model, and the difference data includes surface data and line data, the surface data is the surface data to be updated, and the line data is the line data to be updated.

[0069] In a specific implementation, it is assumed that the model generating device compares the side panel design surface with the preset surface model and determines that the difference data is data corresponding to FS04, FS08, FS09, FC08 and FC09, then the model surface corresponding to the surface data to be updated determined according to the difference data is FS04, FS08 and FS09, and the stop line corresponding to the line data to be updated determined according to the difference data is FC08 and FC09.

[0070] Furthermore, in order to improve the construction efficiency of the side panel design surface model, the step S30 includes: updating the corresponding stop line data in the surface replacement model according to the line data to be updated, and refreshing the data when the data update is completed; when the data refresh is completed, obtaining the side panel design surface model corresponding to the side panel design surface.

[0071] In a specific implementation, the model generation device updates the corresponding stop line data in the surface replacement model according to the line data to be updated, and completes the replacement of the corresponding data in the preset surface model. At this time, a data refresh operation is performed to obtain the side panel design surface model.

[0072] This embodiment determines the surface data to be updated and the line data to be updated according to the side design surface and the preset surface model; updates the corresponding model surface data in the preset surface model according to the surface data to be updated to obtain a surface replacement model; updates the corresponding stop line data in the surface replacement model according to the line data to be updated to obtain a side design surface model corresponding to the side design surface. When the preset surface model needs to be modified, this embodiment updates the corresponding model surface data and stop line data in the preset surface model according to the surface data to be updated and the line data to be updated, respectively, to obtain a side design surface model corresponding to the side design surface, without the need to re-establish the model, and can obtain the side design surface model by updating the original model through surface replacement and line replacement, thereby improving the construction efficiency of the side design surface model.

[0085] Furthermore, in order to improve the generation efficiency of the side panel design surface model, the preset surface model is generated according to the end line and the initial design surface data, including: determining the demoulding angle and demoulding direction corresponding to each end line according to the initial design surface data; generating a main design surface according to the demoulding angle, the demoulding direction and the corresponding end line; generating an angular surface according to the angular surface data determined by the initial design surface data; and generating a preset surface model according to the main design surface and the angular surface.

[0086] It can be understood that the demoulding direction includes an upper demoulding angle, a lower demoulding angle, a front demoulding angle and a rear demoulding angle; the demoulding angle can be the angle at which the main design surface is offset relative to the coordinate axis; the main design surface includes multiple design surfaces, and the upper end line, the lower end line, the first front end line, the second front end line and the rear end line each correspond to a main design surface; generating the main design surface according to the demoulding angle, the demoulding direction and the corresponding end line can be generating the main design surface corresponding to each end line according to the demoulding angle, the demoulding direction and the surface parameters corresponding to each end line; the angular surface can be the connecting surface between the main design surfaces.
