A stage light fixture capable of avoiding lighting in power off includes a light head, a brake motor, an auxiliary power supply, and a controller. The controller is configured to control the brake motor to drive the light head to move to a light-avoiding angle at which strong lighting cannot directly shining into a lighting outlet of the light head and perform power-off processing on the brake motor when the brake motor is switched to be powered by the auxiliary power supply. When the stage light fixture is suddenly powered off, the auxiliary power supply will supply power to the brake motor, and the controller enables a motor unit of the brake motor to drive the light head to move to the light-avoiding angle so as to avoid heat damage to the components inside the light head due to strong lighting irradiation.

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.
