Image processing method and device based on structured light, and mobile terminal

Abstract

The invention provides an image processing method and device based on structured light and a mobile terminal. The method comprises the following steps of acquiring a visible light image of the imagingobject; acquiring depth data indicated by the structured light image of the imaging object; according to the depth data, identifying a first imaging region of an imaging object in the visible light image, and identifying a second imaging region of the article to be worn by the imaging object; according to the relative positions of the first imaging region and the second imaging region, determining an operation region of the image processing operation in the visible light image; performing image processing operation on the operation region. According to the method, the image processing operation can be achieved when the image processing is under beauty mode, so that fuzzy imaging of objects worn by the subject can be prevented, and therefore the display effect of the worn articles can be improved. When the image processing operation is background blurring, fuzzy imaging of objects worn by the subject can be prevented, so that the blurring effect of the visible light image is improved.Meanwhile, the imaging effect of the imaging photo can be improved.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, in particular to an image processing method and device based on structured light and a mobile terminal. Background technique [0002] With the continuous development of mobile terminal technology, more and more users choose to use mobile terminals to take pictures. And in order to achieve a better shooting effect, the relevant image processing means can also be used to process the image. [0003] However, in the actual image processing process, the image effect may deteriorate after image processing. Take the background blur processing as an example. When a user wears earrings, hairpins and other items, the user may want the worn items to be displayed clearly, but does not want the worn items to be blurred. However, in actual operation, the accessories will be blurred and lose a lot of image details. . In addition, when the user turns on the camera to take a beauty photo, a ...

Problems solved by technology

[0003] However, in the actual image processing process, there are cases where the image effect deteriorates after image processing

Take the background blur processing as an example. When a user wears earrings, hairpins and other items, the user may want the worn items to be displayed clearly, but does not want the worn items to be blurred. However, in actual operation, the accessories will be blurred and lose a lot of image details.

In addition, when the user turns on the camera to take a beauty photo, a similar situation will also occur

[0004] Therefore, in the prior art, when performing image processing, in some scenarios, the image effect deteriorates after image processing, and the image processing effect is not good.
