52 Chapter 4: Matrox GatorEye feature reference
Feature name
GevTimestampControlLatchAndReset Copies the value of the internal timestamp counter to the GenICam-standard GevTimestampValue
Feature name
LocatePeakFixedPointPosition
LocatePeakFormat
This subsection lists only the Matrox GatorEye GenICam-extension features. For
a complete list of the transport layer control GenICam-standard features, refer to
the GenICam Standard Feature Naming Convention.
Unless otherwise specified, the data type of the following feature values is integer.
Description
feature and resets the internal timestamp counter to 0.
Note that this feature combines two standard GenICam features: GevTimestampControlLatch and
GevTimestampControlReset.
Laser range control
The laser range control features relate to the control and monitoring of laser line
extraction on-board.
This subsection has no equivalent in the GenICam-standard features.
Unless otherwise specified, the data type of the following feature values is integer.
Description
Feature value
Returns or sets the number of fractional bits to use for fixed-point representation. Note that there are
only 16 bits. The number of bits reserved for the fraction is removed from the number of bits available to
store the integer value of the peak position.
1 - 15
Returns or sets whether to include position or position and intensity in the data sent from the camera.
The laser range operation returns the position information in 16-bit format, while it returns the peak
intensity information in 8-bit format.
Position
PostionAndIntensity
Description
Specifies the number of fractional bits.
Specifies that only the vertical position of the peak should be sent. In the
destination buffer, each Y-position value is saved across two pixels and
every grabbed laser line image is represented using two rows. The
destination buffer must have the same width and height as the laser line
image, even if there are insufficient laser line images to fill the remaining
rows of the destination buffer.
Specifies that the peak intensity value and the ver tical position of the peak
should be sent. The laser range operation uses only an 8-bit destination
buffer to store both the peak location and intensity information; this buffer
must have the same width and height as the grabbed laser line image. In
the destination buffer, each Y-position value is saved across two pixels,
while the intensity is saved in one pixel. Every grabbed laser line image is
represented using three rows: two to store the Y-position and one to store
the peak intensity.
