Abstract
The perception system is the key for autonomous vehicles (AVs) to sense and understand the surrounding environment. Monocular cameras, being cost-effective and mature, are employed to construct a detailed and accurate visual representation of the world surrounding the AV. The objective of this paper is to optimize a camera-based deep learning model with the transfer learning technique on real-time License Plate Recognition (LPR). This paper provides the following original contributions: (1) construct an Ontario license plate dataset, (2) train multiple license plate datasets worldwide using the Convolutional Recurrent Neural Network (CRNN) algorithm with a pre-trained model from a synthetic word dataset, (3) optimize the model by data augmentation methods and a post-processing classifier. The optimized model demonstrated good performance on Ontario LPR, achieving 97.53% accuracy with 72 Frames Per Second (FPS) inference speed.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
