Notice!
If there are not enough successive measurement points on the edges of an EAW, the found
edge positions are shifted away from the edges of the EAW (see figure 4.7, different right
edge position with different parameters for Sequent Hits).
Figure 4.7:
Meaning of Sequent Hits for edge detection
For each EAW, up to two measurement values can be output (configuration with

):
• Edge positions: LX, LZ, RX, RZ (LX = left edge, X-coordinate, LZ = left edge,
Z-coordinate, RX = right edge, X-coordinate, RZ = right edge, Z-coordinate).
• Width of objects: W (calculated from the distance of RX and LX in the X direction).
• Height difference of left and right edge: H (calculated from the distance of RZ and
LZ in the Z-direction).
