Question 450
A rotated document image produces poor OCR while the same text is clear in an upright scan. Which troubleshooting step is primary?
Explanation
Correct Answer
Check orientation, blur, crop and capture quality, using supported rotation/preprocessing to make the source legible before changing the semantic extraction schema.
Incorrect Answers
JSON success can coexist with missing or incorrect OCR values. It does not show that the rotated content was read correctly.
A stricter threshold may suppress results but cannot restore strokes missed because the document is rotated or blurred. Correct capture orientation and legibility first.
More text context cannot reconstruct visual characters that OCR could not reliably observe. The first troubleshooting step is source orientation and supported image preprocessing.
