14.1 Terms and abbreviations
3D image A point cloud where the object shape is represented by three coor‐
dinates.
block In the GigE Vision transport protocol a frame is named block.
buffer Each frame will be received in the PC as one buffer.
frame In Areascan mode: One 2D image.
In Linescan3D mode: A set of 3D profiles. Each line in the frame is
created from one 2D image.
frame rate The rate at which the frames are captured (Hz) in Areascan mode.
GUI Graphical User Interface
height map, depth map A frame where the values represent height or depth and not inten‐
sity.
intensity The intensity value of the pixels in a 2D sensor image.
line Contains one value for each measured point along a cross-section
of the object. Same thing as profile.
line rate The rate at which the lines in a frame are captured (Hz).
NIC Network Interface Card
profile Contains one value for each measured point along a cross-section
of the object. Same thing as line.
reflectance The reflected peak intensity of the laser line when measuring 3D
profiles.
ROI Region Of Interest
scan (verb) To collect measurements made by the 3D camera at one point in
time. That is the same thing as to capture one single profile.
