Abstract
Detekcija tablica na automobilima ima široku primjenu u različitim industrijama i područjima svijeta. Stoga, postoji već mnoštvo sustava i rješenja za ovu primjenu. U ovom radu, realiziran je detektor tablica za vozila u mirovanju koristeći OpenMV H7 Plus kameru. Tehnike računalnog vida koje su korištene su OpenCV, Keras, TensorFlow Lite, Haar-ove kaskade, MicroPython.. Također su korišteni brojni alati za trening klasifikatora i neuronskih mreža, kao i za obradu slike i implementaciju sustava. Neki od njih su Cascade Trainer GUI-a, korišten za trening Haar-ovog klasifikatora i Edge Impulse, korišten za trening neuronskih mreža. Mikrokontroler je programiran u OpenMV IDE-u, koji je napravljen specifično za OpenMV kameru. Datoteke koje sadrže klasifikator i .tflite datoteke neuronskih mreža su učitane direktno u editor. OpenMV IDE radi s kamerom u realnom vremenu tako da je kompletna implementacija testirana direktno na kameri. Krajnji cilj je bio dokazati da se ova konkretna primjena može realizirati s OpenMV H7 Plus kamerom, tako da su krajnji rezultati pozitivni. Dodatna poboljšanja su moguća u vidu treninga s puno većim i kvalitetnijim setom podataka, automatiziranja detekcije i klasifikacije znakova s okvira tablice i omogućavanju rada noću.
Abstract (english)
License plate recognition is widely used in various industries and areas of the world. Therefore, there are already many systems and solutions for this application. In this paper, a plate detector for stationary vehicles was implemented using an OpenMV H7 Plus camera. The computer vision techniques used are OpenCV, Keras, TensorFlow Lite, Haar Cascades, MicroPython, etc. Numerous software tools were also used for training the classifiers and neural networks, as well as for image processing and system implementation. Some of them are the Cascade Trainer GUI, used to train Haar’s classifier, and Edge Impulse, used to train neural networks. The microcontroller is programmed using OpenMV IDE, which is made specifically for the OpenMV camera. Files containing the classifier and .tflite files of neural networks are loaded directly into the editor. The OpenMV IDE works with the camera in real time so the complete implementation is tested directly on the camera. The ultimate goal was to prove that this particular application can be done with the OpenMV H7 Plus camera, so the end results are positive. Additional improvements are possible in the form of training with a much larger and better data set, automating the detection and classification of characters from the table frame and enabling night work.
