Abstract

The invention provides a binocular vision gesture recognition method based on range finding assistance. The method comprising steps of: acquiring an image by using a binocular vision unit and obtaining range finding data by using a range finding unit; and calculating a depth distance between the binocular vision unit and a hand according to the range finding data; processing the image acquired bythe binocular vision unit according to a stereoscopic imaging principle to generate a depth image; and extracting an image with a depth value within a preset range from the depth image according to the depth distance and obtaining a gesture segmentation map; and performing gesture recognition on the gesture segmentation map and outputting a gesture recognition result. The method assists the measurement by the range finding unit, segments a hand region according to the obtained range finding data, can improve the accuracy of the gesture segmentation, and thus improves the accuracy of gesture recognition.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a binocular vision gesture recognition method and device based on ranging assistance. Background technique [0002] Gesture recognition has a wide range of applications in human-computer interaction, game entertainment, and vehicle applications. The gesture recognition device perceives the gesture environment through vision, infrared, radar, etc., and the application of visual perception is the most common. The traditional visual gesture recognition is mainly based on the binocular camera, which collects the depth image through the binocular camera, and then performs gesture feature extraction and gesture classification recognition. [0003] However, there are two deficiencies in the existing gesture recognition based on binocular cameras: 1) some binocular camera devices, such as Microsoft's 3D somatosensory device kinect, can obtain image depth information for gesture ...
