Problems solved by technology

[0004] However, in the prior art, lip language recognition is generally based on a color camera to obtain the user's facial information. This method is easily affected by the environment. For example, if the light is too strong or too weak, it will directly affect the accuracy of image acquisition, resulting in a very low recognition rate. Low, resulting in a low success rate of interaction

Embodiment Construction

[0051] refer to figure 1 , figure 1 It is a schematic flow chart of an embodiment of the self-adaptive lip language interaction method of the present invention. Such as figure 1 As shown, the interaction method of this embodiment includes the following steps:

[0052]101: Acquire a depth image of a target human object and an infrared image or a color image of the target human object.

[0053] Lip language recognition is mainly a process of extracting the characteristic information of the lips of the target human subject, and using the characteristic information to recognize the instruction or voice to be expressed by the target human subject.

[0054] Interaction through lip recognition is widely used because of its simple and convenient operation.

[0055] Since the depth image of the target human object contains more accurate and rich image information of the target human object, and is less affected by light, in this embodiment, the depth image of the target human objec...

Abstract

The invention discloses an adaptive lip language interaction method and interaction apparatus. The adaptive lip language interaction method comprises the following steps: obtaining a depth image of a target human body object and an infrared image or a color image of the target human body object; obtaining lip area images of the target human body object respectively from the depth image and the infrared image or the color image; extracting lip features from the lip area images, and performing lip language identification after fusion processing is performed on the lip features extracted from the depth image and the infrared image or from the depth image and the color image; and converting a lip language identification result into a corresponding operation instruction, and according to the operation instruction, performing interaction. Such a mode is not easily affected by environment such as light intensity, the hit rate of image identification can be effectively improved, the hit rate of lip language identification is further improved, and the execution efficiency and the operation accuracy of the interaction can be finally effectively improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an adaptive lip language interaction method and an interaction device. Background technique [0002] In the field of artificial intelligence and image processing, many functions can be realized by using the image information of the target, such as analyzing the user's expression or action information, etc. Image acquisition and recognition has always been a hot research topic, involving many aspects of users' daily life and scientific research. [0003] For example, the technology of recognizing the user's face, such as lip language recognition, can improve the accuracy of somatosensory interaction and voice recognition, thereby further bringing a more comfortable interactive experience. [0004] However, in the prior art, lip language recognition is generally based on a color camera to obtain the user's facial information. This method is easily affected by the environm...
