The Data Output Format
The image and 3D data output is performed by selecting the data channel DC0-DC2 (node Camera
Controls
→
DataOutput). Depending on the algorithm the data can be acquired by enabling the
corresponding output channel. Every channel is saved in a new image row. The data output can be
performed in 8 or 16 bit mode. In the 8 bit mode the DC0 can be configured to deliver the 8 most
significant bits of the 10 bit intensity data. For the other channels the 8 most significant data bits are
ignored.

Alg. Flags – Output over DC1 (16 bit mode):
Bit14 = LEFT_TRSH_FOUND_FLAG: indicates that the left edge of laser line was found
Bit15 = RIGHT_TRSH_FOUND_FLAG: indicates that the right edge of laser line was found
