METHOD FOR RECOGNIZING GESTURES OF A HUMAN BODY

摘要

A method for recognizing gestures of a human body (10) with a depth camera device (110), having the steps:
generating a point cloud (20) by the depth camera device at a first time (t1) as an initial image (IB);analyzing the initial image (IB) to recognize limbs (12) of the body;setting at least one joint point (14) with a rotational degree of freedom defined by an angle of rotation (α) in reference to a recognized limb;generating a point cloud at a second time (t2) after the first time as a next image (FB);analyzing the next image for a recognized limb and the set joint point from the initial image;determining the angle of rotation of the joint point in the next image;comparing the angle of rotation with a preset value (RV); andrecognizing a gesture upon correlation of the angle of rotation with the preset value.

1. A method for recognizing gestures of a human body by means of a depth camera device, the method comprising the steps of:
a) generating a point cloud by the depth camera device at a first time as an initial image, b) analyzing the initial image to recognize limbs of the body; c) setting at least one joint point with a rotational degree of freedom defined by an angle of rotation in reference to at least one recognized limb; d) generating a point cloud by the depth camera device at a second time after the first time as a next image; e) analyzing the next image with respect to the at least one recognized limb and the at least one joint point set from the initial image; f) determining the angle of rotation of the at least one joint point in the next image; g) comparing the determined angle of rotation with an angle of rotation preset value; h) recognizing a gesture in case of correlation of the determined angle of rotation with the angle of rotation preset value.
