摘要： Methods and systems for controlling lighting fixtures independently with image sensors. In an embodiment, a luminaire includes a controller, an image sensor and wide-angle lens component, and a light source. The controller receives detection signal data from the image sensor and wide-angle lens component when a user is within a detection area associated with a view angle of the wide angle lens, and then determines the position of the user. The controller then controls the illuminance of the light source based on the position of the user. In particular, illuminance is increased as the user approaches a center portion of the detection area, and decreased as the user moves away from the center portion.
