15.6 Description of the "Input" modules – Firmware LG
The following input modules are only available in the LG firmware variant:
●
Line detection
●
Input value of index
15.6.1 "Line detection" module
The "Line detection" module addresses measured values using indices . The indices are assigned to the
ROI groups via a vector with up to 8 values .
You can use single indices or multiple indexes simultaneously (vectors) .
The "Line detection" module has the following settings:

Description
Alignment [1 . .8]
Numerical
Vector with 8 values,
address range from 1-8
The angle between the detected line and the x-axis
(direction of travel) is provided [rad] .
Predictive detection [1 . .8]
Numerical
Vector with 8 values,
address range from 1-8
The distance to the currently predictively detected line is
provided [m] .
Cross-section area line
structure [1 . .8]
Numerical
Vector with 8 values,
address range from 1-8
The cross-section area of the detected line structure in the
y,z plane is provided (heap-like, e .g . swath) .
The value is only available if swath detection is active
(→ „14.3 Automatic ground plane detection“).
Cross-section area line
structure valid [1 . .8]
Binary
Vector with 8 values,
address range from 1-8
The availability of "Cross-section area line structure [1 . .8]" is
provided:
●
"0": cross-section area line structure [1 . .8] not available
●
"1": cross-section area line structure [1 . .8] available
Height line structure [1 . .8]
Numerical
Vector with 8 values,
address range from 1-8
The maximum height of the detected line structure above
the ground level is provided (heap-like, e .g . swath) .
The value is only available if swath detection is active
(→ „14.3 Automatic ground plane detection“).
Height line structure valid
[1 . .8]
Binary
Vector with 8 values,
address range from 1-8
The availability of "Height line structure [1 . .8]" is provided:
●
"0": height line structure [1 . .8] not available
●
"1": height line structure [1 . .8] available
Width line structure [1 . .8]
Numerical
Vector with 8 values,
address range from 1-8
The width of the detected line structure at the ground level is
provided (heap-like, e .g . swath) .
The value is only available if swath detection is active
(→ „14.3 Automatic ground plane detection“).
Width line structure valid
[1 . .8]
Binary
Vector with 8 values,
address range from 1-8
The availability of "Width line structure [1 . .8]" is provided:
●
"0": width line structure [1 . .8] not available
●
"1": width line structure [1 . .8] available
ID [1 . .8]
Numerical
Vector with 8 values,
address range from 1-8
The internal ID of the line is provided .
The ID is not the index . The ID is a unique value .
The ID of a line always remains the same as long as
the line remains detected .
The ID "0" is output if no valid line was detected .
Height offset line structure
[1 . .8]
Numerical
Vector with 8 values,
address range from 1-8
The offset of the maximum height compared to the
centerline of the detected line structure is provided (heap-
like, e .g . swath) . The centerline is described by the normal
offset .
The value is only available if swath detection is active
(→ „14.3 Automatic ground plane detection“).
Height offset line structure
valid [1 . .8]
Binary
Vector with 8 values,
address range from 1-8
The availability of "Height offset line structure [1 . .8]" is
provided:
●
"0": height offset line structure [1 . .8] not available
●
"1": height offset line structure [1 . .8] available
