SIM2REAL provides a synthetic data solution for AI model training via digital-twin virtual simulation environments. Following to the development of Artificial Intelligence, the importance of training data has grown over time. Currently most of the AI training data are obtained at real world and processed to adequate format. However, the data from real world (real data) has clear limitations such as edge-case data shortage and expensive labelling cost. Our synthetic data solution can generate AI training data of various situations, from normal to extreme condition, with affordable cost under virtual environments. Also, we provide robust and effective AI training data through our independent data-centric analysis and domain-randomization algorithm with client customized condition.
