This paper uses a rear sub-frame as the mother model and uses Reverse engineering technology to measure the rear sub-frame point cloud through ATOS non-contact scanners. Then, the point cloud‘s data processing is completed in Imageware. Finally, the point cloud is imported into UG NX4.0 software, after a series of surface cutting, chamfer suturing and sheet thickening; the sub-frame’s three-dimensional model is established. Besides, we complete the static finite element analysis and modal analysis of the sub-frame’s three-dimensional model through the ANSYS software. The results of analysis support theoretical basis for the structural improvement of sub-frame.

The requirement of constructing the three-dimensional entity model for oral cavity teeth has been put forward to the research of the orthodontics based on rapid prototyping technology. This paper compares the merits and demerits of the CT scanning and the structured light scanning and finds a method of acquiring the digital model of oral cavity teeth based on the point cloud. Adopt the structured light scanning technology and 3DSS software to acquire the files of the point cloud data, and introduce the files into GeoMagic software. After processing the data files we obtain the high-quality digital model of oral cavity teeth. The optimal scheme and the processing procedure of the point cloud data in GeoMagic software are described in detail in the paper. In addition, we compare the final solid model and the point cloud data and analyses the errors.

Point Cloud Processing

A reverse engineering based point cloud data acquisition method is addressed. The most critical part of reverse engineering (RE) is data acquisition of the digital model, the quality of design is determined by point cloud data acquisition, which is related to the accuracy of design. The measurement of relative position of different parts has been a difficulty of data acquisition. In this paper, the ATOS optical scanner was used as an example to illustrate the principle of three-dimensional scanner, the positioning methods and procedure of point cloud processing. A case study of point cloud data acquisition of car body was used to illustrate three-point positioning principle, which improves the accuracy of measurement compare with traditional method.

Abstract: In the light of the problem of low efficiency in reverse engineering model reconstruction, taking Auto part as object of study, analysis the key technology in this paper. One method is proposed to improve the design efficiency for Auto part model reconstruction. First of all, point cloud is acquired by camera style 3D scanner and processed by Geomagic software; then it is imported to CATIA software for Parameters reproduction and model reconstruction. Results show that this method can improve the efficiency of Auto part model reconstruction, and provide one workable way for CAD model reconstruction with complex surface.

The authors consider hand-held laser scanners, as a new photogrammetric tool for obtaining three-dimensional models of objects. The principle of their work and the newest optical systems based on various sensors measuring the depth of space are described in detail. The method of simultaneous navigation and mapping (SLAM) used for combining single scans into point cloud is outlined. The formulated tasks and methods for performing studies of the DotProduct (USA) hand-held laser scanner DPI?8X based on a test site survey are presented. The accuracy requirements for determining the coordinates of polygon points are given. The essence of the performed experimental research of the DPI?8X scanner is described, including scanning of a test object at various scanner distances, shooting a test polygon from various scanner positions and building point cloud, repeatedly shooting the same area of the polygon to check the stability of the scanner. The data on the assessment of accuracy and analysis of research results are given. Fields of applying hand-held laser scanners, their advantages and disadvantages are identified.

Tissue Repair And Regeneration

Tissue engineering technology is a promising alternative approach for improvement in health management. Biomaterials play a major role, acting as a provisional bioscaffold for tissue repair and regeneration. Collagen a widely studied natural component largely present in the extracellular matrix (ECM) of the human body. It provides mechanical stability with suitable elasticity and strength to various tissues, including skin, bone, tendon, cornea and others. Even though exogenous collagen is commonly used in bioscaffolds, largely in the medical and pharmaceutical fields, nano collagen is a relatively new material involved in nanotechnology with a plethora of unexplored potential. Nano collagen is a form of collagen reduced to a nanoparticulate size, which has its advantages over the common three-dimensional (3D) collagen design, primarily due to its nano-size contributing to a higher surface area-to-volume ratio, aiding in withstanding large loads with minimal tension. It can be produced through different approaches including the electrospinning technique to produce nano collagen fibres resembling natural ECM. Nano collagen can be applied in various medical fields involving bioscaffold insertion or fillers for wound healing improvement; skin, bone, vascular grafting, nerve tissue and articular cartilage regeneration as well as aiding in drug delivery and incorporation for cosmetic purposes.
