This thesis presents the development of a flexible protective system for hydraulic press-brakes, taking the motion of the worker's hands into account. The proposed innovative solution consists of generating a flexible interdiction zone, whose dimensions and shape depend on the instantaneous velocity of the inspected point, the machine stopping time, and the calculation time of the processing loop. The instantaneous motion of an inspected point on the worker's hand is tracked using camera sets distributing on the different views. The machine is stopped whenever the inspected point interferes with the flexible interdiction zone. The interference between the inspected point and the flexible interdiction zone is verified using the spatial traversability vector. Two approaches relating to the number of inspected points are presented. The inspected point on the worker's hand is a single virtual point in the first principle, whereas several virtual points are in the second principle.;Keywords.
