Comparing 3D foot scanning with conventional measurement methods
BACKGROUND Foot dimension information on different user groups is important for footwear design and clinical applications. Foot dimension data collected using different measurement methods presents accuracy problems. This study compared the precision and accuracy of the 3D foot scanning method with conventional foot dimension measurement methods including the digital caliper, ink footprint and ...
متن کامل3D Dynamic Foot Scanning using Time-of-Flight Cameras
In the literature, most of the systems use laser scanners, multiple video cameras, motion capture systems or projectorcamera sets to measure feet, which can provide high accuracy measurements with sub-millimeter error. However, the shortcomes of these systems are the following: Laser scanners are accurate, but not suitable for capturing dynamic sequences (mechanical moving parts are needed). Mu...
متن کاملUnderwater 3D Surface Measurement Using Fringe Projection Based Scanning Devices
In this work we show the principle of optical 3D surface measurements based on the fringe projection technique for underwater applications. The challenges of underwater use of this technique are shown and discussed in comparison with the classical application. We describe an extended camera model which takes refraction effects into account as well as a proposal of an effective, low-effort calib...
متن کاملThe use of 3D surface scanning for the measurement and assessment of the human foot
BACKGROUND A number of surface scanning systems with the ability to quickly and easily obtain 3D digital representations of the foot are now commercially available. This review aims to present a summary of the reported use of these technologies in footwear development, the design of customised orthotics, and investigations for other ergonomic purposes related to the foot. METHODS The PubMed a...
متن کاملModel-Free 3D Reconstruction of Weld Joint Using Laser Scanning
This article presents a novel utilization of the concept of entropy in information theory to a model-free reconstruction of 3D space in presence of noise. We show that its formulation attains its global minimum at the upper edge of this space to facilitate the extraction of its volume. Furthermore, we present a Monte Carlo approach that is based on the stratification of the sensor information t...
