A photographing device and a method are provided for obtaining depth information, where a binocular manner and a structured light manner are combined, and full depth information of a target object can be obtained. The method may include: obtaining, when a distance between a target object and a photographing device is greater than an effective distance of a structured light manner, depth information of the target object by using a binocular manner; and obtaining, when the distance between the target object and the photographing device is less than an effective distance of the binocular manner, the depth information of the target object by using the structured light manner.
