Scan Mode panel on the Scan page and enable intensity output in the Ethernet panel if intensity data
is required.
Refer to the documentations in the GenTL\ directory for instructions on how to interface to various third
party software.
Gocator GenTL driver packs the part output, intensity and stamps (e.g., time stamp, encoder index, etc.)
into either a 16-bit RGB image or a 16-bit grey scale image. You can select the format in the Go2GenTL.
xml setting file.
The width and height of the 16-bit RGB or grey scale image is calculated from the maximum number of
columns and rows required to support the sensor's FOV and the maximum part length.
16-bit RGB Image
When the 16-bit RGB format is used, the height map, intensity, and stamps are stored in the red, green,
and blue channel respectively.
Channel Details
Red Height map information. The width and height of the image represent the dimensions
in the X and Y axis. Together with the pixel value, each red pixel presents a 3D point in
the real-world coordinates.
The following formula can be used to calculate the real-world coordinates (X, Y, Z) from
pixel coordinates (Px, Py, Pz):
X = X offset + Px * X resolution
Y = Y offset + Py * Y resolution
Z = Z offset + Pz * Z resolution
Refer to the blue channel on how to retrieve the offset and resolution values. If Pz is 0 if
the data is invalid. The Z offset is fixed to -32768 * Z resolution. Z is zero if Pz is 32768.
Green Intensity information. Same as the red channel, the width and height of the image
represent the dimension in the X and the Y axis. Together with the pixel value, each
blue pixel represents an intensity value in the real-world coordinates.
The following formula can be used to calculate the real-world coordinates (X, Y, Z) from
pixel coordinates (Px, Py, Pz):
X = X offset + Px * X resolution
Y = Y offset + Py * Y resolution
Z = 16-bit intensity value
The intensity value is 0 if the intensity image is not available. Gocator outputs 8-bit
intensity values. The values stored in the 16-bit RGB image is multiplied by 256. To
obtain the original values, divide the intensity values by 256.
Refer to the blue channel on how to retrieve the offset and resolution values.
Blue Stamp information. Stamps are 64-bit auxiliary information related to the height map
and intensity content. The next table explains how the stamps are packed into the blue
