Problems solved by technology
[0002] In many practical applications (such as beautification processing), it is necessary to recognize the face orientation to perform different processing for faces with different orientations. However, the results of face orientation detection methods are often not ideal, for example, the face orientation detection is not accurate enough.

The invention discloses a face orientation detection method based on depth. The method comprises the following steps: a main image in current frame scene is processed to judge if a face area exists; when the face area exists, the face area is recognized, and the face area comprises a first face area and a second face area; scene data is processed to separately acquire depth information of the first face area and the second face area; and according to the depth information of the first face area and the depth information of the second face area, a face orientation angle can be calculated. The invention also discloses a face orientation detection device and an electronic device. According to the embodiment of the invention and depth information of different areas of face, the face orientation angle can be accurately calculated and obtained when the face turns, so that the angle can be conveniently used to further process the image, and the user experience is improved.
Description
technical field [0001] The invention relates to image processing technology, in particular to a depth-based face orientation detection method, detection device and electronic device. Background technique [0002] In many practical applications (such as beautification processing), it is necessary to identify the face orientation to perform different processing for faces with different orientations. However, the results of face orientation detection methods are often not ideal, for example, the face orientation detection is not accurate enough. Contents of the invention [0003] Embodiments of the present invention provide a face orientation detection method combined with depth information, a detection device and an electronic device. [0004] The depth-based face orientation detection method of the embodiment of the present invention is used for [0005] Processing the scene data collected by the imaging device, the scene data includes the current frame scene main image, a...
