A rapid shape acquisition method by integrating user touching input

摘要

The easiness of creating three-dimensional (3D) models from physical objects is one of the core challenges that remain to be addressed in reverse engineering. In this paper, a touch-based 3D shape acquisition method is presented that is easy and intuitive to use. Based on the method, a user can easily interact with both real and virtual objects and directly generate feature-based CAD models. The key technical challenges associated with developing the related hardware and software systems are discussed. By using widely available consumer electronic devices, a low-cost prototype system is designed and built. Based on the designed system, a novel 3D coordinate computation method is developed to obtain the touching point positions. Related challenges on using such a system in generating 3D models are also discussed. Multiple examples are presented to illustrate the effectiveness and efficiency of the developed method.View full textDownload full textKeywordsreverse engineering, touch-based system, shape acquisition, augmented realityRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; var addthis_config = {"data_track_addressbar":true,"ui_click":true}; Add to shortlist Link Permalink http://dx.doi.org/10.1080/17452759.2011.599055
