Research On The Technology Of 3D Reconstruction Based On Kinect

With the rapid development of cutting-edge technologies such as computer graphics and computer vision,3D reconstruction technology is widely used in the fields of virtual reality,game modeling,film and television production,and 3D printing.Research on 3D reconstruction has very important practical significance.However,there are some problems and challenges in the process of realistic 3D reconstruction.In order to obtain a realistic 3D object model,this paper studies the realistic 3D reconstruction technology and proposes a Kinect-based 3D object reconstruction scheme.This thesis first proposes a depth data acquisition method for the lack of depth image data.This method is mainly used to solve the problem that the depth images obtained by Kinect are easily disturbed by the surrounding environment.Through this method,the data is collected to obtain high-quality original data,which effectively compensates for the problem of more image holes.For the problem of extracting reconstructed objects,this thesis uses a new object segmentation algorithm to extract target objects.Since the reconstructed object is on a plane,the plane equations can be obtained through the coordinates of multiple point clouds.Then,the object is segmented.For the problem of separating the object from the foreground and the background,the Z value of the depth image is separated,and the point clouds greater than and less than the threshold are removed.The divided point cloud still contains a lot of point cloud data.In order to reduce the amount of subsequent calculations,a hybrid and simplified method is used to simplify the point cloud.When texture mapping is performed on a 3D model,due to changes in environmental conditions such as the perspective and illumination of the texture image,the model is less realistic and there are gaps between the textures.In this paper,based on the existing texture mapping methods,the weights of perspective and distance in texture fusion are increased,and a texture fusion strategy based on composite weights is adopted to largely eliminate the effect of seamsThis thesis researches on the Kinect-based Three Dimensions reconstruction technology,and implements a complete Three Dimensions reconstruction system,and finally obtains the textured object model.The method proposed in this thesis is inexpensive,does not require the use of high-performance equipment,is easy to operate,and can be used in practice.
