Abstract

An apparatus and method for estimating head poses are provided. The apparatus comprises a head area extracting unit used for extracting a head area from an inputted depth image, a head pitch angle estimating unit used for estimating head pitch angles in the head area, a head deflection angle estimating unit used for estimating head deflection angles in the head area, and a head pose synthetizing unit used for synthetizing the head poses based on estimated head pitch angles and estimated head deflection angles. With the apparatus and method adopted, an excellent head pose recognition effect can be realized without being affected by illumination changes.

Description

technical field [0001] The present application relates to the estimation of the head pose of a human body, and in particular to a device and method for estimating the head pose based on a depth image. Background technique [0002] With the development of computer vision technology and pattern recognition technology, human body gesture recognition has been widely used in many fields. For example, human body gesture recognition technology can be applied to human-computer interaction, so as to control equipment more intuitively. Specifically, the human-computer interaction method based on head gesture recognition technology can increase the player's fun in the virtual scene of the game, and can also reflect the user's concerns well in the safe driving support system. In addition, the head gesture recognition results can be used in head-driven animation, and can also be used to achieve natural three-dimensional (3D) interactive operations. In many cases, the detection of sight...
