Abstract

The invention provides equipment and a method for estimating an orientation of a human body. An effective body model is constructed by using a main shaft estimated according to a depth image; and the orientation of the human body is effectively estimated according to an estimated body region. The equipment comprises an image input unit for receiving a shot human body image, a component detection unit for detecting identifiable partial components from the human body image, a main shaft estimation unit for estimating a human body main shaft in a bidimensional space from the human body image based on the detected partial components, a body region estimation unit for estimating the body region in the bidimensional space from the human body image based on the estimated human body main shaft and a human body orientation estimation unit for estimating a human body planar model corresponding to the body region in a three-dimensional space by combining the estimated body region and depth information of the body region in the depth image and estimating the orientation of the human body in the three-dimensional space based on the human body planar model.

Description

technical field [0001] The invention relates to a computer vision graphic recognition technology for estimating the posture of a human body in a three-dimensional space, in particular to a device and method for estimating the orientation of a human body in a three-dimensional space. Background technique [0002] In electronic systems, from the traditional keyboard input, mouse input, joystick input to touch input, voice control input, etc., the interaction mode between man and machine has been constantly developing. Recently, judging the corresponding input command by recognizing the movement changes of the human body in front of the device has become an input method gradually adopted in devices such as game consoles, which is replacing the traditional joystick to realize the control of the game process. In various devices such as game machines, different human body orientations can be defined as different operation instructions, and various control commands can be further d...
