Caméra au sein du réseau de 14 caméras infrarouges de la rue artificielle Streetlab

Camera in the network of 14 infrared cameras in the VICON motion capture system, enabling analysis of the participant’s motor control on the Streetlab artificial street, a platform for improving the mobility of visually impaired people. The participant is fitted with reflective markers placed on anatomical landmarks for motion capture. The position of the markers is determined by triangulation using the network of cameras. This enables precise measurement of the patient's movements and analysis of his motor behaviour (gait cycle, speed, coordination, etc.). The direction of his gaze is also obtained at each stage by means of an eye tracker, which constantly analyses eye movement. All of the strategies that the patient employs to move about and to avoid obstacles are analysed.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
