Mastering the content quality, diversity and context representativeness of a database is a key step to efficiently trained deep learning models. This project aims at controlling the relevant hyper-parameters of training datasets to be able to guarantee a mission performance and to contribute to the explainability of the model behavior. In this presentation, we show an approach to design DRI (Detection, Recognition and Identification) algorithms of military vehicles with different acquisition sources. Starting from a definition of a mission-agnostic image database, this study is focused on controlled image acquisition sources which automates the collection of few but relevant object signatures and their metadata e.g. bounding box, segmentation mask, view angles, object orientations, lighting conditions... By putting the accent on the acquisition of a reduced amount of images coupled with data augmentation technics, it is foreseen to demonstrate a dataset creation method that is fast, efficient, controlled and easily adaptable to new mission scenarios and contexts. This study compares three different sources: an optical acquisition bench of scaled vehicle model, the 3D scanning of scaled models and 3D graphic model of vehicles. The challenge is to make predictions on real situations with a neural network model only trained with the generated images. First results obtained with the datasets extracted from the 3D environment with graphic models and with scanned scaled ones are not yet reaching the previous performance levels obtained with 2D acquisition bench. Further investigations are needed to understand the influence of the numerous hyper-parameters introduced by the 3D environment simulation.
