Introduction
ThankyouforchoosingRangeVisionproduct.
Please read this manual before using RangeVision 3D scanner. Here are described the
procedures for preparing the scanner, installing the required drivers, calibration
procedure, scanning procedure, and tips for acquiring high-quality three-dimensional
object model.
Informationmaybeamendedfromtimetotime.Thesechangeswillbe inserted into the

area. In the majority of cases, scan area is correctly matched,ifthesize of the object

Adjustmentoftheprojectorfocus
Duringthescanneroperationtheprojectorprojectsstructuredlighttotheobject- coded
lines andstripes.Toensurethatthelinesaresharp,theprojectormust be focused on
the working distance of the scanner.
By switching the mode "Lines and Stripes", adjust the focus of the projector, so that the
lines on the calibration plate were as sharp as possible. Using the zoom ring set the
minimum possible area of projector light.

the mounting screws,movethecameratothedesiredposition,and then put the screws

Next, rotate the cameras so that the vertical line of the light cross lies approximately on
the central verticalbluelineinthebothcamera views as shown below. After that,
securely tighten the screws.
