8.2.2 Set Code Reading ROI
Algorithm ROI (Region of Interest) allows the device to execute algorithms and read codes on the
specific area you selected, and thus improving code reading efficiency.
Currently, up to 4 ROIs can be configured, and the device outputs codes according to the number of
ROI (e.g. Region 1, Region 2, and Region 3) in turn. The client software supports drawing single group
of ROI, drawing ROI in batch, and drawing ROI via chessboard.
Note
●
If no code is recognized in the algorithm ROI, and the device will output “noread”.
●
Before drawing ROIs, make sure that there are images in the live view window after stopping
preview.
●
If no algorithm ROI is enabled, and the full screen is the algorithm ROI by default.
●
This function may differ by device models.
Draw Single Group of ROI
Steps
1. Go to Algorithm Settings, click All Features, and find Algorithm ROI.
2. Click Draw to draw ROI in the live view window.
3. (Optional) Repeat the above step to draw multiple ROIs according to actual demands.
Note
The client software only parse codes in the ROI you drawn.
4. (Optional) Set other ROI parameters according to actual demands.
●
ROI Index: It indicates different ROIs and ranges from 0 to 149 which corresponds 1 to 150 ROIs.
●
Draw ROI Width: It refers to the width in algorithm ROI.
●
Draw ROI Height: It refers to the height in algorithm ROI.
●
Draw ROI Offset X: It refers to the X coordinate of the upper left corner in algorithm ROI.
●
Draw ROI Offset Y: It refers to the Y coordinate of the upper left corner in algorithm ROI.
Note
The result of Draw ROI Width plus Draw ROI Offset X cannot be larger than the overall horizontal
resolution, and the result of Draw ROI Height plus Draw ROI Offset Y cannot be larger than the
overall vertical resolution.
5. (Optional) Click Execute in Restore Max. Algorithm ROI to restore the ROI to the full screen.
6. (Optional) Click Execute in Clear All ROI to delete all ROIs.
7. (Optional) Enable ROI Link IO Enable in Algorithm Control, and there will be prompts by the
output device when codes are not read in any ROI.
