7.4.4 Detection Mode
In Detection mode, the Server monitors incoming sensor data to detect the presence of
an object. When an object is detected, data is accumulated by the server. After a
complete object has been captured, data is transmitted by the server to the client. Three
different types of message can be transmitted by the server:
Detection Mode Profile
Message (6), Detection Mode Vision Message (7), and Detection Mode Tracheid
Message (9). Profile messages contain geometric measurements captured using lasers
and profile cameras. Tracheid messages contain spot angle, scatter, and area
measurements captured using lasers and tracheid cameras (if present). Vision
messages contain image pixels captured using LEDs and vision cameras (if available). A
fourth message type,
Encoder Message (15), can be enabled by setting the field
EncoderBatchSize in the server settings file ( Settings.xml ) to a non-zero value. This
message contains batched encoder and timestamp readings at the profile speed for
accurate encoder diagnostics. The batch size is set through the server settings file (see
Section 7.3.1). To toggle between
Encoder Message versions, change the
EncoderMsgVersion parameter in Server Settings .
Message formats are defined below. Note that invalid profile points are represented by
the value -32768, and invalid tracheid angles are represented by the value 255.
