Overview
OMR with Imaging mode represents the latest
advancements in data collection technology. Using
OMR with Imaging mode, you can capture an image of
the entire sheet or specific areas on the sheet. You can
perform heads up editing where you can view an
image of the grid on the sheet while you edit the ASCII
data file. You can perform KFI (key from image) where
you type data into the ASCII data file while viewing an
image of the graybox field (i.e. comments or essay
box). You can read bar codes in both ladder and fence
orientations using your Scantron data collection
software. You can also read machine or handprint data
using optional OCR (optical character recognition) or
ICR (intelligent character recognition) packages.
In OMR with Imaging mode, the scanner must be
connected to a PC with ScanTools software. The
software controls the scanner and captures the data.
When a new session is initiated, the software sends a
“scan sheet” message to the scanner and the scanner
responds by scanning a sheet. As each sheet is
scanned, the scanner sends an image of the entire
sheet back to the scanner for processing.
Once the image is received by the software, the data is
extracted based on the form definition in the software.
OMR bubble grids are resolved by the software and
are converted to their ASCII equivalent. Image data is
saved for each image clip area that was specified in
the form definition. Bar code image data is converted
to its ASCII equivalent. And, if optical character
recognition (OCR) or intelligent character recognition
(ICR) is being used, those grids are converted to their
ASCII equivalent as well.
