Abstract
A guiding system guides an autonomous movable object. The guiding system has a time-of-flight imaging system, which has a first light source to illuminate a first field of detection; and a light sensor. The light sensor detects first and second reflected light. The first reflected light has light emitted by the first light source reflected at the first field of detection. The second reflected light originates from a second field of detection illuminated by a second light source, which is independent from the first light source and is coupled to a different movable object. The imaging system differentiates between the first and second reflected light, determines a depth map of the first field of detection based on the detected first reflected light, and generates feedback. The imaging system has a motion controller that receives the feedback, and modifies a motion of the autonomous movable object based on the feedback.
