Character segmented modeling method

Abstract

The invention relates to a character model reconstruction method, and discloses a character segmented modeling method. The method includes: building a character head model by employing a three-dimensional scanner to acquire cloud data of character head points; pre-processing the built character head model, and obtaining the pre-processed character head model; simplifying the pre-processed character head model by employing an edge collapse simplification method based on edge curvature and area error, and maintaining detail features of the character head model by employing an interactive method; and performing matching and fusion of the obtained character head model and a human torso model in a human torso database, and finally obtaining a complete human body model. According to the method, the modeling efficiency is improved, the diversity of models is enhanced, and the application value in crowd simulation is high.

Description

technical field The invention relates to a modeling method, in particular to a character segmentation modeling method. Background technique Because of its accuracy, intelligence, and strong operability, computer group animation has achieved good results in animation animation, online game production, traffic management, crowd evacuation, and disaster escape. How to carry out 3D modeling of the real human body and apply it to crowd animation is an important challenge faced by the current crowd animation simulation system. Traditional 3D human body modeling usually uses structured light or laser scanners. Although high-precision personalized 3D human body models can be obtained, the cost is high and the operation is complicated. The Kinect device launched by Microsoft uses infrared technology to achieve quick and low-cost acquisition of three-dimensional information. This breakthrough has greatly promoted some applications using 3D technology, such as Kinect-based human act...
