Line Scan Camera Tool
The Line Scan Camera tool adds a camera to the camera toolbar. This
camera has unique options that allow the camera to out put images from
specific lines of the image that has been taken. The user can set what
lines will be given and in what style the images will be given in the
viewer. This outputs a live action shot that can be useful for scanning
images on a conveyor belt or for similar purposes.
Using the Line Scan Camera Tool
Drag 'n' drop the Line Scan Camera tool from the ROTCam to the ROTMain.
Save the Workspace.
Reload the Workspace. These steps must be taken in order for the camera to appear as an option within the camera toolbar.
Click on the camera options within the camera toolbar until it displays the LS Camera.
Right Click on the LS Camera option to pull up the tools properties page.
Camera Index: This option
allows the user to select which camera they are using if more than one
camera are installed. If there is only one camera enter a one here. If
there are two camera's and the user wishes to use the second camera
enter a two here etc.
Height: This allows the user to
define how many images will be used within the line scan. A height on
100 means that 100 images will be compiled into the scan.
FillStyle: This option describes how the images will be displayed. There are three options here stack, push, and scroll.
Stack: this option stacks the images from the bottom up and scrolls them over the viewer.
Push: this option stacks the images from the top down and scrolls them over the viewer.
Scroll: this option does a continuous circular loop of the images.
Line NB: The line number allows the user to choose the line that the camera will be capturing and scrolling through the viewer.
Line Count: This option allows
the user to choose multiple lines. For example if we give a line NB of
100 and a line count of 5, the image will be displaying lines 100-104.
Line Negative: If this box is
checked it will reverse the order of the Fill Style. So if it is set to
Stack the images it will reverse the order that it is stacking the
images so it will go top down instead of bottom up.
Event Count: When the camera is
taking multiple images this option allows the user to adjust how often
the viewer will refresh. If this option is set to one (1) then the
viewer will reset every time an image is captured. If it is set to two
(2) it will reset every other time an image is captured and so on.
Once all of the changes are made within the tool select the Apply button.
Use the camera toolbar to run the tool (select "live" mode).
