Abstract: Sign language information processing method and apparatus, an electronic device and a readable storage medium provided by the present disclosure, achieve real-time collection of language data in a current communication of a user by obtaining voice information and video information collected by a user terminal in real time; and then match a speaking person with his or her speaking content by determining, in the video information, a speaking object corresponding to the voice information; and finally, make it possible for the user to clarify the corresponding speaking object when the user sees AR sign language animation in a sign language video by superimposing and displaying an augmented reality AR sign language animation corresponding to the voice information on a gesture area corresponding to the speaking object to obtain a sign language video. Therefore, it is possible to provide a higher user experience.

Abstract: A method and apparatus for augmenting reality are disclosed. A specific embodiment of the method includes: recognizing an object in an image collected by a camera of a user terminal, and determining a space occupied by the recognized object in a world coordinate system; determining a position in the world coordinate system corresponding to an augmented reality tag of the recognized object, and determining a superimposition position in the collected image corresponding to the position in the world coordinate system corresponding to an augmented reality tag of the recognized object, the position in the world coordinate system corresponding to the augmented reality tag being associated with the space occupied by the recognized object in the world coordinate system; and superimposing, in an augmented reality, the augmented reality tag at the superimposition position. The direct association relationship between the superimposed information and the object in the real world is established.
