For more information see the XClick command. Video, PDF and during robotic desktop automation (RDA). So it works absolutely on every web page, image, IDE Click (locator) commands is that this works 100% visually. They key difference to the "good old" selenium UI.Vision RPA searches for the text, and then clicks on it. When you specify XClick with OCR text as input, Very useful for robotic process automation (RPA). XClick/XMove | ocr=text to Process Automation: These commands use OCR to find a certain text and then do something. Text Recognition Commands without Extraction If you still encounter OCR quality issues, please ask in the RPA software forum. !OCRTableExtraction=true/false If true, it makes sure that the OCR results are line by line. !OCRScale=true/false enlarge the image before applying OCR. !OCREngine=1/2 select OCR Engine1 or 2. You can use the following parameters (= internal variables) to control the quality: The RPA software uses the companion OCR.Space OCR API (also from us). How to debug screen-scraping with OCRExtractRelative. How to debug issues with OCRExtract and OCRExtractRelative So the "only" difference is the input, the regular Is that OCRExtract regex works on the OCR text result, and the sourceSearch regex works on the HTML page source code. command works just as sourceExtract | regex=. Result of the complete active screenshot area, and the match(es) are returned. The regular expression is applied to the OCR Option 3: Use regular expression to extract text (available soon, contact us for early beta access))Īnother method is regex=(regular expression). OCRExtractRelative runs Zonal OCR on area marked with the pink box. UI.Vision RPA ships with the "DemoPDFTest_with_OCR" macro that shows how to get text from any PDF. You load the PDF into Chrome, and then use OCRExtractRelative command toįind the area with the text and extract it. The OCRExtractRelative command is the best solution to extract text from PDF for specific coordinates. Of the pink box marks the point to click. (3) For XClickRelative/XMoveRelative the middle (center) (2) For visionLimitSearchAreaRelative the pink box marks the new search area for computer vision. (1) For OCR (as in the video), the pink box marks the text area to read. The difference is the meaning of the pink box: The green box is always the anchor image. The green/pink box principle is used for all. OCRExtractRelative is explained in this video. Here we read the temperature from a mobile phone app via a remote desktop connection. Only the area inside the pink box is used as input for OCR. So only the content of the pink rectangle is used as input for OCR. And the OCR text result is stored in the variable. The key difference here is that the content of the This method uses the green/pink box scheme, as described in the relative clicks section. Option 2: OCRExtractRelative - Define OCR area in image with green and pink boxes That is why we recommend to use OCRExtractRelative. Of the image area changes a lot, then the image is no longer found reliably. UI.Vision RPA looks for the image, and then extracts the text from it. Option 1: OCRExtract - Define OCR area via image There are two ways to specify the text to extract: OCRExtract | image | variable and OCRExtractRelative | image | variableĭo you need to extract values from a video, scrape text from an image or extract text from a PDF? Websites, canvas objects, inside images and videos and for PDF testing.Įnable and test the text recognition on the OCR tab, and combine them with XClick. Thus, it works equally well on a simple website and on highly complex Just like the automated UI test commands, it works independently of the HTML page source codeĪnd document browser object. Optical Character Recognition (OCR) works on screenshots of the rendered web page. UI.Vision RPA can use OCR to search for text on the screen. Text Recognition (also called Screen Scraping, OCR) You have the additional option to do web scraping with selenium ide commands. If the data is part of a regular website, Visual screen scraping can be used on the desktop and in the browser.įor browser automation, screen scraping inside theīrowser is the only option if you want to extract data from a PDF, image or video. The sections below describe how to do screen scraping with UI.Vision RPA technically. User Manual: Screen Scraping with Computer Vision (OCR) Screen scraping: We use OCRExtractRelative to extract the temperature from the remote desktop display of a smartphone app. Terminal, remote desktop (RDP), mobile phone emulators and even the new Amazon (AWS) AppStream secure application streaming service. UI.Vision RPA essentially adds an “Data API” to every Windows, Mac and Linux application. With its accurate OCR screen scraping features Data extraction (“Screen scraping” ) is a very important technique in data migration and
