In this sense, this work proposes the use deep learning to identify the presence or lack of a retaining ring at a vehicle axis end from images. A convolutional neural network was used to learn features from images e to perform classification. The system was evaluated using a dataset of images collected in a real industrial environment. Despite the dataset imbalance, the method yielded maximum results in sensitivity, specificity and F1-score. Thereafter, the neural network architecture was optimized (90% reduction of the number of parameters) to increase computational efficiency.
