Light fixture, in particular a light fixture for stage

A computer-vision system is equipped with a first camera and a second camera spaced apart from each other and enables acquisition of a first image and a second image of a light beam that propagates from a light-beam source towards a target position of the light beam. The first image and the second image of the beam differ from each other as a result of the first camera and the second camera being spaced apart from each other. The system produces a disparity map of the first image and second image of the beam to be projected in a three-dimensional point cloud starting from the disparity map according to point-cloud-projection calibration data that set in relation disparity maps for reference images with respective three-dimensional point clouds.

Light fixture and method for operating said light fixture

A lighting apparatus for show-business or entertainment sector comprises a light-radiation generator for projecting a lighting beam towards a lighting space that includes one or more undesired lighting zones. A motorization causes the lighting beam to scan the lighting space as a function of scanning-control signals as received by the lighting apparatus.
