Problems solved by technology

[0003] In the process of realizing the disclosed concept, the inventors found that the gesture recognition method of ordinary RGB cameras is easily affected by the interference of ambient light and complex background color changes, making gesture recognition poor in stability, while the gesture recognition method of TOF cameras is stable. Good, but limited by the manufacturing process, its field of view FOV is small, resulting in a small effective range of gesture recognition

Abstract

The present disclosure provides a recognition method, which is applied to an electronic device capable of recognition based on an RGB camera and a TOF camera. The method includes: when the target is within the field of view of the TOF camera: using a depth image acquired by the TOF camera, Recognizing the target object; and when the target object moves out of the field of view range of the TOF camera: according to the corresponding relationship between the depth image and the RGB image, using the first area feature information of the target object obtained in the depth image obtained by the TOF camera, Obtaining the second area feature information of the target object from the RGB image acquired by the RGB camera; and identifying the target object based on the second area feature information and utilizing the RGB image acquired by the RGB camera. The present disclosure also provides an electronic device.

Description

technical field [0001] The present disclosure relates to an identification method and electronic equipment. Background technique [0002] Gesture interaction is an important function of AR devices. Traditional AR devices either implement gesture interaction based on the gesture recognition method of ordinary RGB cameras, or realize gesture interaction based on the gesture recognition method of TOF (Time of flight) cameras. [0003] In the process of realizing the disclosed concept, the inventors found that the gesture recognition method of ordinary RGB cameras is easily affected by the interference of ambient light and complex background color changes, making gesture recognition poor in stability, while the gesture recognition method of TOF cameras is stable. Good, but limited by the manufacturing process, its field of view FOV is small, resulting in a small effective range of gesture recognition. Contents of the invention [0004] One aspect of the present disclosure pro...
