Design and development for generation of real object virtual 3D model using laser scanning technology

Abstract

Technology has evolved to generate or recreate anything that human brain is capable of dreaming. Many centuries old artefact was found in museum. A damaged and a recreated artefact both were kept adjacent to each other. The effort to recreate the replica of the model was a biggest challenge. This paper proposes to develop a real-time stationary 3D scanning system. The system scans a real object to translate into a virtual object. The associated data is utilised to build 3D digital model. A LASER unit operating at 650 nm with tilting angle of 600 is spaced 15 cm from web-cam. A triangulation technique helps to capture images in the range of 26 cm. Further, segmentation and contours estimate point cloud of the object. It is observed that developed model has an accuracy of 92-96% and relative error of 2-8%. The model is validated on conical flask, tiffion box and coffee mug objects. 3D scanners can be used in applications such as 3D printing, restore and recreate archaeological artefacts and in entertainment industry.
