Images that compose training datasets are often collected directly from the production line and labeled with bounding boxes manually. Such data represent well the inference context but might lack diversity, implying a risk of overfitting. To address this issue, we propose a dataset construction method based on an automated pipeline, which receives a CAD model of an object and returns a set of realistic synthetic labeled images (code publicly available). Our approach can be easily used by non-expert users and is relevant for industrial applications, where CAD models are widely available. We performed experiments to compare the use of datasets obtained by the two different ways - collecting and labeling real images or applying the proposed automated pipeline - in the classification of five different industrial parts. To ensure that both approaches can be used without deep learning expertise, all training parameters were kept fixed during these experiments. In our results, both methods were successful for some objects but failed for others. However, we have shown that the combined use of real and synthetic images led to better results. This finding has the potential to make industrial OD models more robust to poor data collection and labeling errors, without increasing the difficulty of the training process. specialized 122 39 3 415-432 2023 0824-7935 https://www.documentation.ird.fr/hor/fdi:010090490 10.1111/coin.12572 0824-7935 [F B010090490] https://www.documentation.ird.fr/hor/fdi:010090490 https://www.documentation.ird.fr/intranet/publi/2023-11/010090490.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2023-11-03 2025-02-24 fdi:010090490 fre
