AI OCR & OCV
Read and verify printed text. OCR reads it. OCV checks it.
The DaoAI ACI OS — OCR reads characters such as serial numbers, date codes and component markings. OCV checks printed text against the expected content. Choose recognition or verification to match the inspection task.
OCR and OCV are the read-and-verify pair in DaoAI's (微链道爱) ACI OS: OCR reads serial numbers, date codes and component markings; OCV checks printed text against the expected content. The boundary between them is the task — "what does it say" is OCR, "does it say what it should" is OCV. Component-maker markings on the inspected part are inspection objects.
OCR reads unknown text. OCV verifies known text.
RECOGNITION
OCR: Read it
What does this say?
| USE IT WHEN | Read serial numbers, date codes, lot codes and component markings without entering the expected text first. |
| WHAT YOU GET BACK | Recognized text saved with the inspection results, including serial numbers for unit-level traceability. |
| HANDLING SIMILAR CHARACTERS | Configure character equivalence groups to help reduce false calls caused by similar-looking characters. |
VERIFICATION
OCV: Check it
Does this say what it should?
| USE IT WHEN | Verify known text, such as component codes, designators and fixed board markings. |
| WHAT YOU GET BACK | Verification results showing whether the expected text is present, correct and legible. |
| WHY USE VERIFICATION | OCV checks against the expected text rather than identifying each character without a reference. |
WHY YOU WANT BOTH
Use OCR to capture variable text, such as serial numbers. Use OCV to verify expected text, such as component codes. Both can be used on the same board for different inspection needs.
Similar characters. Configurable rules.
Some printed characters look alike, depending on the font and print quality. Four default equivalence groups help you handle these similarities.
| 0 O | Zero and the letter O can look alike. |
| 1 I L | Similar strokes can make these characters hard to distinguish. |
| 5 S | Print quality can obscure the difference between 5 and S. |
| 8 B | Ink spread can make the shapes of 8 and B look similar. |
Four things printed on a board.
Component markings
Read component codes, date codes and manufacturer markings directly from the component body.
Board silkscreen
Read designators and other text printed on the board.
Barcodes and QR codes
Read barcodes and QR codes on boards or panels during inspection.
Serial numbers
Save each unit’s serial number with its inspection results for traceability.
