Abstract
A structured light depth sensor for sensing a depth of an object, comprises: a projector for projecting structured lights with different codes to the object; a camera located on one side of the projector and configured for capturing the structured lights reflected by the object; a storage device for storing parameter information of the camera and distance information between the projector and the camera; and a processor electrically connected to the projector, the camera, and the storage device. The processor controls the projector to sequentially project the structured lights with different codes to the object, controls the camera to sequentially capture the structured lights reflected by the object, and calculates the depth of the object. A sensing method adapted for the structured light depth sensor is also provided.
