The difficulties in reading QR codes on surfaces that are not flat or are deformed have motivated researchers from the University of Barcelona and the Universitat Oberta de Catalunya to develop a methodology that can enhance the recognition of QR codes in challenging physical environments. The new system is designed to work on QR codes found on surfaces like bottles or food trays, providing a solution that combines a generalist approach with two-dimensional barcodes to improve the recognition of digital information. This innovative approach, detailed in a study published in Pattern Recognition Letters, offers a versatile solution to the problem of reading complex QR codes accurately.
QR codes, a type of barcode that can store information in a two-dimensional matrix of black and white pixels, have transformed the way users access digital information. However, factors like image quality, print quality, and the flatness of the surface can make it challenging to scan these codes accurately. The new algorithm developed by the research team takes advantage of the specific patterns within QR codes to extract details about the underlying surface on which the code is placed. By employing mathematical functions known as splines, the algorithm can adjust the topography of the surface locally, ensuring more accurate readings of the code.
Despite the advancements in QR code recognition, there are still technological challenges that need to be addressed to improve the overall process. Ensuring correct and reliable readings, preventing attacks that could modify the code, and increasing the speed of capture are key areas that require further research and development. The team at ColorSensing, a spin-off company from the University of Barcelona, is actively working towards these goals and has received recognition for its innovative approach to smart labelling and reducing food waste.
