Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0035] In various tasks such as sensor simulation, object recognition, scene understanding, and robot simulation, people tend to replace real scenes with virtual simulation scenes due to the problems of high manual collection costs, high manual labeling costs, and uncontrollable data quality in real scene data. data for applied research in a virtual simulation environment. When establishing a virtual simulation scene, the existing three-dimensional model without physical and interactive attributes is often converted into a virtual scene through a series of processing.

The invention discloses a three-dimensional model splitting method and device, computer equipment and a storage medium, and the method comprises the steps: splitting a model component into a plurality of sub-components with disconnected topologies based on the vertex connection relation of the model component, and achieving the segmentation of objects with different semantics through the process, meanwhile, in order to solve the problem that the model component is excessively segmented, after an incidence matrix between the sub-components is constructed according to the shortest distance between the vertexes belonging to different sub-components, the sub-components are clustered according to the incidence matrix between the sub-components and a preset clustering distance; in this way, the over-segmented same semantic objects are combined in a clustering mode, the obtained clustering cluster serves as a new model component, the clustering cluster is closer to single object data of single semantics contained in each component, the accuracy is high, and the method is suitable for application conversion of a three-dimensional model. Moreover, the splitting process is simple in method, short in operation time consumption and capable of saving calculation overhead cost.
Description
technical field [0001] The invention belongs to the field of splitting of three-dimensional models, and in particular relates to a splitting method, device, computer equipment and storage medium of three-dimensional models. Background technique [0002] In research and production, it is often encountered that the 3D model data needs to be split and clustered according to semantics. For a 3D model composed of multiple model components, due to negligence or mistakes of designers, subcomponents corresponding to objects with different semantics are included in the same model component, making the semantics of the model components unclear. [0003] Patent application document CN104794316 A discloses a method for splitting and combining 3D models. For a splittable 3D model, the 3D model is manually split into sub-modules through mouse operation, and then according to the collision detection between the sub-modules and the original The adjacent relationship in the 3D model is comb...
