4 Functionality
4.8 Additional 3D Functionality
4.8.1 Mode Settings
The Peak Detector functionality in the MV-D1024E-3D01-160 camera can be configured in
different modes, depending on what image information should be transfered from the camera
to the frame grabber. The following settings can be selected:
2D Mode
In the 2D mode the camera sends raw image data to the frame grabber, which can then be
further processed on the frame grabber or by an image processing software tool. No
additional 3D information is transferred with the raw image data when using the 2D mode.
Combined 2D/3D Mode
In the combined 2D/3D mode the camera sends the raw image data including the necessary 3D
information to the frame grabber. The raw image containing the laser line is analyzed by the
Peak Detector in the camera’s FPGA. This 3D information is then attached to the 2D raw image.
The laser line needs to be aligned in vertical orientation towards the camera.
Only a single vertical laser line can be processed at a time by the 3D Peak Detec-
tor algorithm.
✎
If your application requires to process multiple laser lines please contact Photon-
focus to discuss possible firmware adaptions.
The combined 2D/3D mode is typically used for simultaneous image analysis of 2D and 3D
images or to set up the laser triangulation system.
3D Mode
In the 3D mode the camera only sends the 3D data calculated by the Peak Detector algorithm
in the camera FPGA to the frame grabber.
4.8.2 Threshold
The raw image data are first processed by the threshold pre-filter before being analyzed by the
Peak Detector algorithm.
The threshold must be set above the image background otherwise the 3D data
may be incorrect.
