System for following actors on at least one performance stage

A system for tracking performers on a show stage, including:

• a plurality of light or video projectors to track the movement of the performers on the stage,
• at least one motorized yoke having at least two axes of rotation with direct axial drive for the support and the omnidirectional movement of an assembly comprising:
• an image acquisition assembly formed of a color camera and of a neuromorphic camera, and having a common objective lens, to receive images of the performers performing on the stage,
• a dichroic mirror separating and directing the image collected through the common objective lens, on the one hand towards the color camera and on the other hand towards the neuromorphic camera, and
• an image processing module to receive, from the neuromorphic camera, event-related images of the performers performing on the stage in order to determine their coordinates and to receive, from the color camera, visible images of these performers allowing them to be identified if necessary, and
• a display screen to display a visible image of each of the performers performing on the stage obtained by the color camera and to allow the assignment by an operator at a control terminal or a media server of the determined light or video projectors to identified performers on the stage, in order to ensure automatic tracking by the light or video projectors of the respective movements of these identified performers.

A method for tracking performers on a show stage including:

• orienting towards the stage at least one motorized yoke supporting an image acquisition assembly formed of a color camera and of a neuromorphic camera, and having a common objective lens,
• obtaining an event-related image of each of the performers present on the stage by the neuromorphic camera and obtaining a visible image of each of the performers performing on the stage by the color camera,
• identifying the performers and determining the coordinates of each of them based on their event-related image and their visible image,
• displaying, on a display screen, a visible image of each of the performers performing on the stage to allow the assignment by an operator at a control terminal or a media server of the determined light or video projectors to identified performers on the stage, in order to ensure automatic tracking by the light or video projectors of the respective movements of these identified performers.
