Abstract
Abstract. Hand-held 3D scanning systems are increasingly available on the market from several system manufacturers. These systems are deployed for 3D recording of objects with different size in diverse applications, such as industrial reverse engineering, and documentation of museum exhibits etc. Typical measurement distances range from 0.5 m to 4.5 m. Although they are often easy-to-use, the geometric performance of these systems, especially the precision and accuracy, are not well known to many users. First geometrical investigations of a variety of diverse hand-held 3D scanning systems were already carried out by the Photogrammetry & Laser Scanning Lab of the HafenCity University Hamburg (HCU Hamburg) in cooperation with two other universities in 2016. To obtain more information about the accuracy behaviour of the latest generation of hand-held 3D scanning systems, HCU Hamburg conducted further comparative geometrical investigations using structured light systems with speckle pattern (Artec Spider, Mantis Vision PocketScan 3D, Mantis Vision F5-SR, Mantis Vision F5-B, and Mantis Vision F6), and photogrammetric systems (Creaform HandySCAN 700 and Shining FreeScan X7). In the framework of these comparative investigations geometrically stable reference bodies were used. The appropriate reference data was acquired by measurements with two structured light projection systems (AICON smartSCAN and GOM ATOS I 2M). The comprehensive test results of the different test scenarios are presented and critically discussed in this contribution.
Highlights
Portable 3D scanning systems are increasingly used today in many different applications due to their high flexibility, portability and efficiency
The ATOS system generated the reference data set for Testy, while the wheel hub and the bust of Einstein were measured with the smartSCAN
The test results are only valid for the specific model of each system investigated, i.e. it does not represent a universal statement about the respective product series of the hand-held 3D scanning system
Summary
Portable 3D scanning systems are increasingly used today in many different applications due to their high flexibility, portability and efficiency. It is a challenge today to select a suitable 3D scanning system for a concrete application due to the current technological variety of available 3D scanning systems. For the investigations presented in this contribution the following current hand-held 3D scanners were tested using the same procedures and the same test and reference bodies as published in the previous investigations at HafenCity University Hamburg: four systems from Mantis Vision (F5-B, F5-SR, F6 SMART and PocketScan 3D), Artec Spider, Creaform HandySCAN 700 and the FreeScan X7 from the Chinese company Shining 3D
