Problems solved by technology
[0002] With the technical development of electronic equipment, in order to meet the different needs of users, the number and types of cameras in terminals (such as mobile phones) are increasing. Terminals that can acquire depth images and visible light images at the same time have gradually become a trend. Due to the relatively mature development of visible light images , the imaging quality has been able to meet the user's expectations, but the development time of the depth image is relatively short, due to the limitations of resolution, depth calculation method and other factors, the imaging quality is still low

Embodiment Construction
[0021] Embodiments of the present application will be further described below in conjunction with the accompanying drawings. The same or similar reference numerals in the drawings represent the same or similar elements or elements having the same or similar functions throughout. In addition, the embodiments of the present application described below in conjunction with the accompanying drawings are exemplary, and are only used to explain the embodiments of the present application, and should not be construed as limiting the present application.
[0022] At present, due to the rise of mobile devices, users are shooting more and more portrait data, and the requirements for portrait shooting are also getting higher and higher. In addition to obtaining visible light images of portraits, it is also necessary to obtain portrait depth maps. The depth map method is mainly obtained through dual-camera stereo matching, time of flight (TOF), structured light ranging, etc. These different...

The invention provides an image processing method. The method comprises the following steps: acquiring a first depth image and a first visible light image; identifying a portrait in the first visible light image to obtain a first processing image after the portrait is dug out; and performing guided filtering on the first depth image by taking the first processed image as a guided image to generate a filtered image. According to the image processing method and device, the terminal and the readable storage medium, the depth image and the visible light image are acquired at the same time, then the portrait in the visible light image is identified and the portrait cutout is performed, and then the cutout visible light image is taken as the guide image, so the guide filtering of the depth image is realized, and the error of the depth information corresponding to the edge of the portrait is repaired, so that the repaired filtered image is generated, and the imaging quality of the depth image is improved. And the visible light image with the higher resolution is utilized to perform guided filtering on the depth image with the lower resolution, so that the noise reduction and detail smoothing effects on the depth image can be improved.
Description
technical field [0001] The present application relates to the field of image technology, and in particular to an image processing method, an image processing device, a terminal, and a non-volatile computer-readable storage medium. Background technique [0002] With the technical development of electronic equipment, in order to meet the different needs of users, the number and types of cameras in terminals (such as mobile phones) are increasing. Terminals that can acquire depth images and visible light images at the same time have gradually become a trend. Due to the relatively mature development of visible light images , the imaging quality has been able to meet the expectations of users, while the depth image development time is relatively short, due to the limitations of resolution, depth calculation methods and other factors, the imaging quality is still low. Contents of the invention [0003] Embodiments of the present application provide an image processing method, an...
