Description
Feature value
Returns or sets the number of laser-line images (frames) to create an uncorrected depth map for an
object in a scene. The laser range operation captures the specified number of frames, extracting the
information to create an uncorrected depth map and, then sends that uncorrected depth map as a single
image to the Host computer.
1 - 600
Returns or sets whether the laser range operation is enabled, and the type of extraction mode to use. Your
Matrox GatorEye assumes that grabbed images are of a laser line.
Off
CenterOfGravity
Returns or sets the minimum average intensity level required to record a position. The columns that do
not have a peak detected above this threshold will have their positions written as the maximum possible
value of the destination position buffer and will be considered to be invalid positions.
1 - 255
Returns or sets the value to be returned if the position of the laser line is not found in a column.
Value
Returns or sets the expected width of the laser line in the internally grabbed image. The laser line
operation uses this value as the size of the neighborhood to average when scanning a column for the
highest average intensity. Setting the width to be wider than the actual laser line width might cause the
operation not to find the line unless the minimum required intensity level is lowered; this is because
non-laser line pixels might be included and lower the average. This will also reduce the accuracy of the
position. Setting the width to be too narrow makes the search susceptible to noise.

Matrox GatorEye GenICam-extension features
Description
Specifies the number of frames.
Disables the laser range operation. Note that the camera will send raw
images.
Specifies that the laser range operation should be performed and to use
center of gravity mode. In this mode, the operation finds the neighborhood
in each column with the greatest average intensity and records the
average as the peak intensity value for that column. The sub-pixel
weighted center of the neighborhood is record as the position of the peak
intensity value. Note that the camera will no longer send raw images.
Specifies the minimum average intensity level.
Specifies the value to be returned.
Specifies the width, in pixels.
