“…A complete and exhaustive study on the state-of-the-art of these techniques can be found in [3][4], where a set of solutions are introduced that allow acquiring transparent, semi-transparent and highly reflective objects. Some of the proposed solutions consider the fabrication of specific devices for the acquisition of transparent glass using structured UV light [5], infra-red cameras [6], polarization and phase-shifting devices for the acquisition of translucent artifacts [7] or even submerging the original artifact inside a tank filled with a fluorescent fluid [8]. Other solutions combine the use of a video camera recorder, a moving spotlight and a small sphere [9] or a turntable together with a set of cameras, lights and monitors [10].…”

-This paper faces the problem of acquiring archaeological artifacts using triangulation based 3D laser scanners and focusing on reflective/refractive surfaces. This kind of artifacts are mostly made of glass or polished metal, and the properties of their surfaces violate most of the fundamental assumptions made by vision algorithms. Also, the unique and fragile nature of archaeological artifacts adds an extra limitation to the acquisition process: using industrial whitening sprays has to be avoided, due to the physicochemical processes required to clean the surface after scanning and because the chemical properties of these sprays may damage the original object. As an alternative to them, a new application of a common conservation material is proposed: the use of cyclododecane as a whitening spray. Thanks to its chemical stability and to the fact that it sublimes at room temperature, together with its good film-forming capabilities, a set of evaluation tests is presented to prove that the error introduced by the opaque thin layer created on the surface of the artifact is smaller than the accuracy of the 3D scanner and, thus, no acquisition errors are introduced. A comparison with general-purpose industrial whitening sprays is also presented, and achieved results show no significant differences in the quality of the resulting 3D models.

“…The studies presented in this article on the 3D scanning of specular surfaces are related to a non-conventional infrared approach introduced by Eren [21] for the 3D digitization of glass objects. Unlike classical active triangulation approaches, the principle of this technique, called "Scanning From Heating" (SFH), is based on the measurement of the infrared radiation that is emitted by the object instead of the reflection of visible radiation.…”

International audienceMany experimental techniques and many com- mercial solutions have been proposed to realize non-contact 3D digitization of industrial objects. Unfortunately, the per- formances of active 3D scanners depend on the optical prop- erties of the surface to digitize. That is why the results obtained by active 3D triangulation on specular or transparent surfaces are not as good as those obtained on diffuse surfaces. In this paper, we present the developments we have realized to address highly reflective metallic surfaces. These develop- ments are based on the extension of a technique, called "Scan- ning from heating" and initially dedicated to glass material. In comparison to conventional active triangulation techniques that measure the reflection of visible radiation, we measure here the thermal emission of a surface, which is locally heated by a laser source. We describe in this paper the successive steps we have followed to adapt Scanning From Heating to metallic materials, to evaluate the performances and finally to develop an operational prototype

“…Besides laser and camera, there are various way that used for distances measurement tools in 3D scanning: infrared [18]- [21], ultrasonic sensor [22]- [26], scanning from heating methods [27] are various ways using imaging and sensors methods [19], [28]- [31] for 3D image reconstruction.…”

Three-Dimensional scanning is a method to convert various distances set into object visualization in 3-dimensional form. Developing a 3D scanner has various methods and techniques depending on the 3d scanner's purpose and the size of the object target. This research aims to build a prototype of a 3D scanner scanning small objects with dimensions maximum(10x7x23)cm. The study applied an a-three dimensional(3D) scanner using infrared and a motor to move the infrared upward to get Z-ordinate. The infrared is used to scan an object and visualize the result based on distance measurement by infrared. At the same time, the motor for rotating objects gets the (X, Y) ordinates. The object was placed in the center of the scanner, and the maximum distance of the object from infrared was 20cm. The model uses infrared to measure the object's distance, collect the result for each object's height, and visualize it in the graphic user interface. In this research, we tested the scanner with the distance between the object and infrared were 7 cm, 10 cm, 15 cm, and 20 cm. The best result was 80% accurate, with the distance between the object and the infrared being 10cm. The best result was obtained when the scanner was used on a cylindrical object and an object made of a non-glossy material. The design of this study is not recommended for objects with edge points and metal material.
