Poster summary

Assessing athletes' performance is a constant challenge for coaches. Taekwondo methods of evaluation used are mainly manual. Research in motion analysis area has enabled the development of affordable and easy to access technological solutions. This study presents a friendly and low-cost system for assessing the performance of Taekwondo athletes in real time. The system uses a 3D camera with depth sensor, a computer, a software developed for data collection and processing and Inertial Measurement Units (IMUs). Aiming to identify and quantify the movements performed by the athlete during training sessions using deep learning techniques applied to the data collected in real time. Several approaches and methodologies were tested along with a dataset previously developed in order to define which one presents the best results. The best results were obtained with convolution layers models, such as, CNN, LSTM and ConvLSTM, with more than 90% in terms of accuracy validation.
