If it shows not feasible, I'm sure that you can do this with some python a RPi and stream the image data with some simple HTTP (base 64, you know). This is a great machine learning project to get started with computer. If you want a software-only solution, you can always convert the barcode to the vertical lines and play with their distance, which should also not be a problem for the LX6 beast (Or, would it?). In this post, I will show you how to build a barcode and Qr code reader using Python. Thresholds and color filtering should be good for the ESP32 to handle. That is a hardware solution, with some very simple computer vision. Now setup some thresholds and you should be able to see only the light on top of the white parts. But I can't find a way to calculate the input() to be called second time. And scan the same qr for the second time to end the recording. The image above shows a barcode on a white background with a 7pt green line with 50% opacity on top of it. I am trying to use a qr scanner to scan qr code as input name to start recording video. Go ahead and 3D print a case for the ESPcam and the laser, tweak some camera parameters (exposure and brightness) and see if the image gets you some results. It is a useful library for image processing. Finally, loop through the results and show the recognized type and code text. Call the readbarcodes () method and get recognition results. OpenCV is an open-source computer vision and machine learning library. We can read QR code in Python with Aspose.BarCode for Python by following the steps given below: Create an instance of the BarCodeReader class. Most of the python programmers are familiar with OpenCV and Numpy libraries. For this program, we need three packages, which are OpenCV, NumPy, and pyzbar. If you have a laser (I would recommend green, based on some 3D scanning tests in the past) and a camera, why not trying to make it happen? Let’s create a program that scans the QR codes and Barcodes from an image. Laser barcode scanners work by shining a laser line on the code and reading how the light reflects back to it. The following code sample shows how to read a QR code in Python. By doing this, you can understand more about the dependencies of the project. Setup a Python Environment It is recommended to set up an isolated environment for Python projects. The second one is used to read the information of barcode and QR code in real time. After installing Zbar and OpenCV, we created two Python scripts: The first one is used to scan the barcode and QR code on a single image. Let’s start by importing all the libraries into our python file. Call the readbarcodes () method and get recognition results. Using Python you can generate your own QR code, customize it, and decode information from a QR code. In this article, we discussed how to build a barcode and QR code scanner with OpenCV and Python library Zbar. I don't happen to have one of these with me, but I think you could have some fun with a laser and some CV. We can read QR code in Python with Aspose.BarCode for Python by following the steps given below: Create an instance of the BarCodeReader class.
