Gesture recognizing and controlling method and device thereof

摘要

A gesture recognizing and controlling method and device thereof are provided. The gesture recognizing and controlling method includes the following steps. First, a pending image having depth information is captured, in which the pending image includes a human form image. The human form image is analyzed so as to obtain hand skeleton information having a first skeleton and a second skeleton. It is determined whether the first skeleton and the second skeleton have an intersection point. If yes, it is determined whether an included angle formed by the first skeleton and the second skeleton is within a predetermined angle range. When the included angle is within the predetermined angle range, a controlling signal is output accordingly.

1. A gesture recognizing and controlling method, comprising:
capturing a pending image having depth information, wherein the pending image comprises a human form image; analyzing the pending image first by adopting a Blob detection thereby determining a number of connected area in the pending image; analyzing a first barycenter position of a first connected area and a second barycenter position of a second connected area in the pending image when the number of connected area is two; and outputting another controlling signal correspondingly according to a variation of a barycenters-connection length between the first barycenter position and the second barycenter position; analyzing the human form image to obtain hand skeleton information having a first skeleton and a second skeleton, wherein the first skeleton and the second skeleton respectively corresponding to a left hand and a right hand of the human form image; determining whether an intersection point exists between the first skeleton and the second skeleton; determining whether an included angle formed by the first skeleton and the second skeleton is within a first predetermined angle range if the intersection point exists, wherein the intersection point segments the first skeleton into a first segment and a second segment, and the intersection point segments the second skeleton into a third segment and a fourth segment; outputting a controlling signal when the included angle is within the first predetermined angle range; calculating a first ratio between the first segment and the second segment, and calculating a second ratio between the third segment and the fourth segment; and outputting a controlling signal based on the first ratio and the second ratio.
