Detecting Barcodes in Images with Python and OpenCV ...

· Sadly it’s only working for the first barcode in the zip.. The others are not found. Either only parts are detected or some text is marked 🙁. Whats interesting is that the results (the rectangle marking the barcode) differ from opencv to with opencv also not finding the barcode. I tested python and with both opencv and Maybe you could revise this tutorial given you …

python - How to detect lines in OpenCV? - Stack Overflow

· Edit: Using VeraPoseidon's Houghlines implementation and the second library linked here, I've managed to get the following result for intersection detection. Credit to Vera and the library author for their good work. The green squares represent a detected intersection. There are a few errors, but this seems like a really good starting place to me. It seems as though most of the locations you actually want to detect an intersection have multiple intersections detected…
