Apparatus and method for estimating head pose

Abstract

A device and method for estimating a head pose are provided, the device comprising: a head region extracting unit for extracting a head region from an input depth image; a head pitch angle estimation unit for Estimating the head pitch angle in the middle; the head deflection angle estimation unit, which is used to estimate the head deflection angle in the head region; the head pose synthesis unit, which is used to synthesize the head based on the estimated head pitch angle and head deflection angle posture. According to the device and method, a good head gesture recognition effect can be achieved 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...

Problems solved by technology

However, the existing head pose recognition schemes based on global geometric features are often difficult to achieve good recognition results when the illumination changes are large or the image resolution is low.
