Method and device for acquiring depth information of object, and recording medium

A device for acquiring depth information of an object, the device comprising:

• a sensing unit configured to sense the object located at a first point in a common sensing region common to respective sensing regions of a plurality of sensors, acquire first shape information of at least one view point of the object located at the first point and, when the object is located at a second point in a region excluding the common sensing region, second shape information of the object at the second point on the respective sensing regions of the plurality of sensors;
• and
• a controller configured to acquire first depth information of the object at the first point and, based on a result of comparison between the first shape information of the at least one view point and the second shape information and the first depth information, second shape information of the object at the second point.
