Abstract

The goal this article is to show an alternative to the process of making orthoses of a lower limb through of 3D scanning system of cost low. This alternative eliminates the plaster process traditionally utilized in the manufacture of orthoses of the lower limb. Therefore, was done an analysis of the manufacturing process orthoses in a specialist manufactory in a Porto Alegre – RS city. After that was done a 3D scanning in a subject for verification of possibility to make a virtual 3D model of the scanned leg. The 3D scanner utilized during the 3D scanning process was the Kinect device of the Microsoft. Thus, the manufacturing process orthoses by 3D scanning obtained satisfactory results, may be a solution for replaced of plaster model in the manufacturing process. The work is in progress for verification and analysis of precision between the plaster models and virtual model obtained through of the low-cost 3D scanning system.

The purpose of this article is to evaluate the feasibility of parameterization of custom basic molds, eliminating the need for making a mold for each user. This method uses the three-dimensional scanning to obtain the anthropometric measurements, and the user’s body silhouette and parameterize these measures, causing the production of a single basic mold is necessary to meet users with different anthropometric characteristics. A low-cost 3D scanner was used, Microsoft Kinect, to obtain the 3D model of the user’s body and the Grasshopper modeling algorithm for setting the mold. Thus, a research participant was scanned and, from your 3D model, anthropometric measurements were obtained for setting the mold. The final model was built and experienced by the participant for validation purposes. The results were satisfactory in showing high precision in anthropometric model produced. Thus, the study addressed brings important contribution to the development of products for clothing in areas as they provide flexibility in the basic mold production process and product measurements with high accuracy and hence increase the degree of comfort for the user.

The aim of this paper is comparing both tridimensional scanners: white light Artec Eva; and Infra-red light Microsoft Kinect. This comparison enables evaluate possibilities of these equipments for developing user-centered product projects. It was carried out comparison's concerning both precision and dimensional deviation through virtual and physical models generated by CAD and CAM systems. It was verified the need of eliminating the human body movement by using physical models in the performed analysis. As a result, both scanners demonstrated measurement precision, with the advantage of Artec Eva over Microsoft Kinect. The selection of the most appropriated scanner concerning the projects needs evolves factors such as: the available cost for the project; and the required precision fidelity for the aimed product. Both digital scanners considered in this paper contribute to the development of customized products, showing the relationships between tools and needed product fidelity.

The aim is to develop a method for obtaining anthropometric parameters using a low cost three-dimensional digitizer. The research methodology is divided in five steps: literature review; collection and analysis of anthropometric data using the direct method and also the development of the indirect method for obtaining anthropometric measurements; comparison and data analysis; discussion of results and the completion of the research. The digitization process developed it is based on Microsoft Kinect, a low-cost device, and also on the software kscan3D. For the anthropometric collection from the three-dimensional model is used Autodesk 3D Studio Max. This research presents requirements and constraints for generate the three-dimensional model in order to obtain a mesh with satisfactory precision. It is presented a flowchart to guide the implementation of the developed method in the design process as well as a summary table containing guidelines for this application. The developed method achieved 97.96% of compatibility considering the results of the measured variables in relation to the direct method. These results were obtained with an exposure time of the individual of only 3 minutes and 28 seconds, which is less than the time required in the direct method – 1 hour and 12 minutes. This demonstrates one major contribution of the developed method.
