The fusing of panoramic camera data with laser scanner data will be discussed on measurement results obtained during verification tests using the Digital 360° Panoramic camera (M1) developed by German Aerospace Center (DLR) in cooperation with Kamera & System Technik GmbH (KST) and the imaging laser scanner (3D-LS) developed by Institute of Navigation University Stuttgart (INS). First the measu...

OVERVIEW: Ultrasound diagnostic scanners have gained broad acceptance in a wide range of diagnostic fields because they are able to make observations inside the body safely and in real time. In keeping with the developments in signal processing technology and semiconductor technologies, resolution and other functions were dramatically improved through the use of digital ultrasound scanners deve...

BACKGROUND The procedure for making impressions of multiple implants continues to be a challenge, despite the various techniques proposed to date. The authors' objective in this case report is to describe a novel digital impression method for multiple implants involving the use of stereophotogrammetric technology. CASE DESCRIPTION The authors present three cases of patients who had multiple i...

This contribution gives account of one of the results achieved by the group MAPA (Models and Algorithms for the digital documentation of Architectural Heritage) that integrates the IMAP3D group and the DAVAP group. The group work is based on the assumption that preservation of cultural heritage is a responsibility for the whole cartographic community and that the recent advances in Digital Imag...

STATEMENT OF PROBLEM Little peer-reviewed information is available regarding the accuracy and reproducibility of digitally fabricated casts compared to conventional nondigital methods. PURPOSE The purpose of this in vitro study was to compare the accuracy and reproducibility of a digital impression and cast fabrication with a conventional impression and cast fabrication. MATERIAL AND METHOD...

In the Fourth Industrial Revolution, research and development of application technologies that combine high-tech have been actively conducted. Building information modeling (BIM) technology using advanced equipment is considered promising for future construction projects. particular, a 3D laser scanner, LIDAR expected to be solution building safety inspections. This work proposes new method eva...

We propose a novel scanner characterization approach for applications requiring color measurement of hardcopy output in printer calibration, characterization, and diagnostic applications. It is assumed that a typical printed medium comprises the three basic colorants C, M, Y. The proposed method is particularly advantageous when additional colorants are used in the print (e.g. black (K)). A fam...

I MOIRE PATrERNS AND TWO· DIMENSIONAL ALIASING IN LINE SCANNER DATA ACQUISITION SYSTEMS C. D. McGillem T. E. Riemer I The basic mechanism underlying the generation of Moire patterns in line scanner data acquisition systems is examined. A general expression 1s developed in terms of typical system parameters for the reproduced image of such systems and the interaction of the image spectrum; the r...

Extracting forest variables from airborne laser scanner has less than 10 years of history. During that time, however, a new area in the field of forest studies has emerged. This paper describes existing algorithms and methods of airborne laser scanning that are used for forest measurements. The methods are divided into the following categories: 1) extraction of DTM (digital terrain model), 2) e...
