Embodiment 1

[0080] Such as figure 1 As shown, a crowd generation simulation system based on an image segmentation algorithm includes: a crowd simulation character model library, a character texture map library, a character model texture map library, a texture map processing module, a texture map model mapping module, a character model processing module, Character streamlined model library, model drawing module and complete character library.

[0081] The crowd simulation character model library stores a large number of crowd models required for crowd simulation, including low-level models and high-level models, as well as character models that are processed for realization, personalization, and complexity in order to improve the diversity of crowd simulation crowds. The character models in the crowd simulation character model library can be obtained in a variety of ways. The character models can be obtained by manual modeling or by scanning people with 3D scanning tools. The character mod...

Embodiment 2

[0123] This embodiment is carried out according to the following steps, and the specific process is as follows figure 2 shown. This embodiment is based on a computer system, using tools such as maya and matlab to operate.

[0124] This embodiment is to simplify the character models in the character model database in the original crowd simulation system according to the system and method of the present invention, so as to optimize the existing crowd simulation crowd models, and basically achieve the original On the basis of the diversity of crowd simulation crowd models, the use of system resources is reduced, and the calculation efficiency of the original crowd simulation is increased to achieve the effect of high calculation efficiency.

[0125] Step (1): call the crowd simulation character model. The model called as image 3 shown.

[0126] Step (2): Draw and save the texture map for the appearance of the character model or use the existing texture map. The texture map...

Embodiment 3

[0150] The invention also provides a crowd simulation database. After the invention is established, the crowd simulation character model library, character texture map library, character model texture map library, texture map processing module, texture map model mapping module, character model processing module, character simplified model library, and model drawing module And other modules will collect a large amount of data and information about the crowd simulation crowd, and with the growth of the system operation time, the database of the system will become very rich and powerful, thus providing a rich database for future crowd simulation. And it will become more abundant with the passage of time, which has great value and significance for future crowd simulation.

Abstract

The invention discloses a crowd generation and simulation method and system based on an image segmentation algorithm. The crowd generation and simulation method comprises the following steps of constructing a crowd simulation three-dimensional person model or selecting an existing three-dimensional person model from a crowd simulation person model library; carrying out texture map drawing on the appearance of the three-dimensional person model and storing the texture map; unfolding an original texture map, storing the unfolded original texture map in a person model texture map library, and extracting the texture map from the person model texture map library; carrying out segmentation treatment on the texture map by using the image segmentation algorithm, and canceling superfluous edge andpoint in the texture map, so as to obtain a new texture map; mapping the new texture map on the three-dimensional person model; canceling superfluous edge and point of the three-dimensional person model, so as to generate a new person model; storing the new person model in a person reduced model library; giving the new person model to the original texture map, storing the new person model with thetexture map, and storing in a complete person library. The simulation calculation efficiency of a crowd is improved.

Description

technical field [0001] The invention relates to the technical field of crowd simulation, in particular to a crowd generation simulation method and system based on an image segmentation algorithm. Background technique [0002] Nowadays, people pay more and more attention to crowd simulation technology, and at the same time, there are more and more applications of crowd simulation. Due to the increasing population and the high density of crowds in key public places, the large number of crowds brings Various issues deserve attention. At present, crowd simulation is applied in many fields, such as path planning for crowd evacuation, flow of people in public places, crowd simulation in crowded places, etc. [0003] At present, the demand for crowd simulation is increasing day by day, especially for crowd simulation with high degree of simulation, high crowd diversity, high interactivity, and high computing efficiency. Now the crowd simulation is relatively real and impressive. ...
