Design And Implementation Of 3D Model Reconstruction System Based On 2D Photograph

With the rapid development of technologies such as virtual reality,augmented reality and deep learning,3D model reconstruction of target characters through photos has become an important research direction in the field of traditional modeling and deep learning.Fast and accurate restoration of 3D models from photos can greatly simplify the process of 3D modeling,save manpower and material costs,and make the modeling process semi-automated or even fully automated,which provides great significance for sports,movies,games and other fields.The author combines the linear mixed skinning algorithm to design an algorithm based on photo information to restore the human body state features,and uses the algorithm to reconstruct the 3D model of the character,and further designs and implements the 3D model reconstruction system based on 2D photos.This system is mainly used for the reconstruction of the three-dimensional model of the character.The system can construct a three-dimensional model that conforms to the shape characteristics of the target person according to the photo of the character,and can combine the motion data to realize the automatic rotation of the model.Based on the research background and significance of the topic,this thesis introduces the related methods and related technologies of 3D modeling of common characters,and analyzes the requirements of photo-based 3D model reconstruction system.Based on the analysis of demand,an algorithm(BTHM)based on photo information to restore the state of human object is studied and designed.The overall design of the 3D model reconstruction system based on the algorithm is expounded,including the design,algorithm and system of system ar-chitecture and process.Basic data structure design,system interface design,and system function module design required.On this basis,functional modules such as data analysis,data preprocessing,general model construction,and model adjustment are designed and implemented.Then the function test of the 3D model reconstruction system is carried out.The similarity between the model and the target person through system reconstruction is analyzed.The effectiveness of the system is verified and the scallability of the system is expounded.Finally,through the two aspects of algorithm and system,the design and development process of the whole system is summarized,and the next step is forecasted.
