3D Scanning Technology Overview
F6 SMART™ – Volumetric Handheld Camera – User Guide
Contact scanning.
Non-contact Scanning.
Non-contact solutions are further divided into two (2) main categories:
Active scanning.
Passive scanning.
There are several technologies that fall under each of these categories. Mantis Vision’s
solutions are classified as Non-Contact Active Scanning category and its Active scanners
emit light and detect its reflection passing through cameras to probe an object or
environment.
Mantis Vision employs Structured-light 3D scanning technique which projects a pattern
of light, formed by a patented filter, on the subject. An Near-Infra-Red (NIR) Sensor,
offset slightly from the pattern projector, examines the shape of the pattern and
calculates the distance of every point in the field of view.
The advantage of Structured-light 3D scanners is speed and precision. Compared to
scanning one point at a time, Structured-light scanners scan multiple points up to an
entire field of view at once. Scanning an entire field of view in a fraction of a second
reduces or eliminates the problem of distortion from motion.
Other Mantis Vision Ltd. systems are also capable of scanning moving objects in real-
time.
Mantis Vision’s 3D Scanning Technology
Mantis Vision’s technology was developed to enable 3D capturing of highly dynamic
scenes for high-resolution model creation.
3D shapes and objects are captured during free motion, and tolerates operation from
moving platforms. This is achieved by projecting a single coded-light pattern, which
contains all the indexing information required by our Structured Light triangulation
algorithms. This way, a complete 3D range-image is captured by a single “camera
snapshot”.
Mantis Vision Ltd. developed a unique single pattern codification method allowing the
distinct identification of hundreds of times more points than any other method availably
in the market today. Despite the code’s “shortness” (i.e. made of a single pattern only), it
incorporates a powerful error detection/correction mechanism.
As a result, the technology provides several unique and highly beneficial attributes:
