Abstract: A depth information processing method and a depth information processing system using the same are provided. The method includes the following steps. A pixel shifting process is performed on a first image and a second image of an original image group to obtain a zero-shifted first image and a shifted second image of a shifted image group. The original image group and the shifted image group are combined to obtain a combined image. A depth information processing is performed on the combined image to obtain an initial depth information. The initial depth information has a basic depth information corresponding to the original image group and a compensated depth information corresponding to the shifted image group. A numerical restoration process is performed on the compensated depth information to obtain a restored depth information. The basic depth information and the restored depth information are fused to obtain a fused depth information.

Abstract: A remote control system includes an object detection unit, an object determination unit, and a static gesture processing unit. The object detection unit detects an object corresponding to an operator according to a depth image including the operator and a face detection result corresponding to the operator. The object determination unit utilizes a combination of a gesture database, a color image of the object, and a two-dimensional image corresponding to the depth map to determine a gesture formed by the object when the operator moves the object to a predetermined position. The operator moves the object to the predetermined position and pulls the object after the operator moves the object to the predetermined position within a first predetermined period. The static gesture processing unit generates a first control command to control an electronic device according to at least one static gesture determined by the object determination unit.
