Product Specification
3.1 Introduction
The MV-D1024E-3D01-160 is a CMOS camera from Photonfocus optimized in two aspects for
laser triangulation applications. The camera includes an image processing module, that runs an
algorithm called Peak Detector. The Peak Detector algorithm is able to compute with sub-pixel
accurracy the peak position of a laser line. Thus, the height profile of an object gets computed
within the camera, making additional calculations in the PC obsolet.
In several applications solved with laser triangulation setups it was shown that the use of the
LinLog
®
response curve leads to better triangulation results, since information is not getting
lost by saturation of the laser line. The triangulation is getting more stable and independent of
the object surface properties.
The camera is built around the monochrome CMOS image sensor A1024B, developed by
Photonfocus. The principal advantages are:
• High reliability of 3D reconstruction, due to the non-linear interpolation technique used
in the peak detection algorithm
• Peak detection with up to 1/64 subpixel accuracy
• Less post-processing necessary for obtaining perfectly smooth surfaces
• Extremely high image contrast achieved by LinLog
®
technology
• Stabilization of laser triangulation applications independent from object surfaces
• Detection of small features on the inspected parts due to decreased noise sensitivity
• Combined 2D/3D applications can be realized in the 2D/3D mode of the camera
• Global shutter
• Region of interest (ROI) freely selectable in x and y direction
• Stabilization of laser triangulation applications independent from object surfaces
• Detection of small features on the inspected parts due to decreased noise sensitivity
• Several simultaneously selectable read out windows: Multiple region of interest (Multiple
ROI)
• The camera has a digital CameraLink
®
interface (CL base configuration)
• Grey level resolution up to 12 bit
• The compact size of only or 55 x 55 x 40 mm

make the MV-D1024E-3D01-160 camera the
perfect solution for applications in which space is at a premium
The basic components for 3D imaging consist of a laser line and a high speed CMOS camera in
a triangular arrangement to capture images (profiles) from objects that are moved on a
conveyer belt or in a similar setup (see Fig. 3.1).
You can find more information on the basics of laser triangulation and on the
principles of 3D image acquisition technique in the user manual "PF 3D Suite"
