I foud that tesseract OCR engine is not good enough for reading seven segment display.

I&rsquo;ve played with tesseract and text. It worked very well. I hadn&rsquo;t considered 7 segment display recognition. I wanted to trend radon readings in my house with tesseract looking at my radon detector but it has a 7 segment display. I will read up on ssocr, new to me. &nbsp;</p><img src="https://community.element14.com/aggbug?PostID=26206&AppID=402&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/sci-pi-design-challenge/b/blog/posts/any-measurement-to-pi---blog-6-finding-best-orc-technique-for-raspberry-pi-part-2Mon, 19 Jun 2023 19:52:02 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:ede52427-70fd-4c9c-9f1e-367b01580331DAB1<p>As I said earlier, OCR results can be very interesting, but incorrect.</p><img src="https://community.element14.com/aggbug?PostID=26206&AppID=402&AppType=Weblog&ContentType=0" width="1" height="1">
