Scanning a Document from an Image

Document Detection

ScanbotSDK.detectDocument(imageFileUri: string)

The Scanbot SDK uses digital image processing algorithms to find rectangular, document like, polygons in a digital image. This function applies edge detection and processes all image operations in a background thread. There will be no UI started. As input, a file URI of an image must be passed. The output contains the Detection Result as a string and on success the cropped and perspective corrected image as a new file as well as the detected polygon. If there was no document detected the result enum provides the exact reason (noisy background, too dark, etc). The input image file will not be modified.
