Embodiment 1

[0081] The image processing method based on multi-scale transformation in the embodiment of the present invention, such as image 3 shown, including the following steps:

[0082] Step 301 , for the same target object, collect multiple images corresponding to different focus distances.

[0083] Step 302: Perform pixel alignment processing on the feature points in the multiple images to obtain multiple images after pixel alignment processing.

[0084] Step 303 , performing image fusion processing on the aligned multiple images to obtain a clear panoramic depth image.

[0085] Adopt the embodiment of the present invention, the image in step 301 is the original image, such as taking a landscape photo, within the span range of the focus distance, select several different focus distances, and take the landscape picture at the same position, you can get multiple images. The span range of the focus distance, taking an example of a terminal with a zoom lens, is a range from wide ang...

Abstract

The invention discloses an image processing method based on multi-scale transform and a terminal. The method comprises: with regard to the same target object, acquiring a plurality of images corresponding to different focusing distances; performing pixel alignment on feature points in the plurality of images to obtain a plurality of pixel-aligned images; and fusing the plurality of aligned images to obtain a clear panoramic depth image. By adopting the method, a panoramic depth image can be conveniently and quickly obtained.

Description

technical field [0001] The present invention relates to image processing technology, in particular to an image processing method and terminal based on multi-scale transformation. Background technique [0002] With the intelligent development of terminals, smart terminals are used by more and more users. When a user uses a smart terminal, multiple applications can be installed on the terminal device, such as image acquisition and image processing through a camera application to obtain the final imaged image. Taking the terminal as a mobile phone as an example, it is hoped that the final imaged image will be a full-depth image. The full-depth image means that the depth of field range in the image extends from a very close range to infinity, and all parts of the image are in focus. However, due to the limited focus adjustment range of the mobile phone, the depth of field range of the collected images is not large enough, so that it is impossible to conveniently obtain images w...
