Defining the ROI
The defined ROI should cover the whole sensor region where the laser line variations occurs. The initial step is to set a full resolution ROI to verify the overall image.
To create a full resolution ROI, the ScanLength and BufferHeight must be set to the same Height value set on the “Remote Device” (camera). All these parameters can be seen in the in the “GenApi” tab of the “Data Streams” module as shown hereafter:
Full resolution ROI
The resulting frame can be seen in the following figure where it is possible to verify the effective region where the laser line variations occur.
