3D Scanning Technology Overview
F6 SMART™ – Volumetric Handheld Camera – User Guide
● High accuracy levels of depth measurements.
● Ability to capture images while in free motion – the camera, the object and the
captured environment can both be freely moving.
● Dense sampling at high resolutions of hundreds of thousands of points per single
frame.
● No dependency on color or texture and the ability to project at invisible wavelengths
such as Infrared (IR).
● Operation under challenging lighting conditions.
● Ability to acquire challenging targets, such as shiny and largely contrasted surfaces.
How does it Work?
The complete Mantis Vision system includes two (2) components:
● A 3D acquisition unit (The Camera) and
● A software application to process, manipulate and visualize the 3D data.
The camera, which necessitates single hand operation, consists of dual video camera
channels (color and depth) and a light projector, all embedded into a single ergonomic
handheld device.
Capturing the 3D environment is like using a regular (2D) video camera. The only
difference between a 2D video camera and the Mantis’ 3D Camera is the type of flash
light (projector) used.
The system acquires the scene’s depth by projecting invisible (infrared) light onto the
environment through a mask containing one of Mantis Vision’s proprietary patterns.
Figure 1 – The Principle of Active Triangulation
This projected and distinctly-marked infrared light reflects from the surface of the scene
and absorbed by both the color and depth cameras.
Active triangulation is the common method for 3D coordinate data acquisition. The
“trick” is the use of stereoscopic parallax to get the information about the third
dimension.
