Embodiment 1

[0033] An embodiment of the present invention provides a panoramic photographing method, such as figure 1 shown, including:

[0034] S101. The mobile terminal acquires the first frame of image captured by the lens in the first direction and the second frame of image captured in the second direction, wherein the first area of ​​the first frame image overlaps with the second area of ​​the second frame image .

[0035] It should be noted that the first frame image and the second frame image are two adjacent frames of images taken in the panoramic photographing mode, the size of the first frame image and the second frame image are the same, and the first frame image is the same as the first frame image. The second regions of the two frames of images have the same size.

[0036] Exemplarily, assuming that the first frame image is the previous frame image of the second frame image, the first area of ​​the first frame image may specifically be the right half of the first frame imag...

Embodiment 2

[0075] An embodiment of the present invention provides a mobile terminal 60, which is used to execute the panoramic photographing method provided in Embodiment 1 of the present invention, specifically as Figure 6 As shown, it includes: an acquisition unit 601 , a first determination unit 602 , an extraction unit 603 , a second determination unit 604 , and a splicing unit 605 .

[0076] Wherein, the acquiring unit 601 is configured to acquire the first frame of image captured by the lens in the first direction and the second frame of image captured in the second direction, wherein the first area of ​​the first frame of image and the area of ​​the second frame of image The second area overlaps.

[0077] The first determining unit 602 is configured to determine the characteristic corner points of the first area and the characteristic corner points of the second area.

[0078] The extraction unit 603 is configured to extract the characteristic corner points of the first region a...

Abstract

The embodiment of the invention provides a panoramic photographing method and a mobile terminal. By means of the panoramic photographing method and the mobile terminal, the operation difficulty can be lowered on the premise of guaranteeing photo quality, user experience is improved. The method includes the steps that a first frame of image shot by a lens in the first direction and a second frame of image shot by the lens in the second direction are obtained, wherein the first region of the first frame of image and the second region of the second frame of image are overlapped; characteristic angular points of the first region and characteristic angular points of the second region are determined and extracted, and a first characteristic angular point set and a second characteristic angular point set are obtained respectively; matched characteristic angular point pairs are determined from the first characteristic angular point set and the second characteristic angular point set according to a preset rule, wherein the matched angular point pairs are N pairs of characteristic angular points corresponding to one another in the first characteristic angular point set and the second characteristic angular point set, and the N is larger than or equal to three and is an integer; the first frame of image and the second frame of image are spliced with the positions of the matched characteristic angular point pairs as the benchmark. The panoramic photographing method and the mobile terminal are suitable for the technical field of electronic information.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a panoramic photographing method and a mobile terminal. Background technique [0002] In order to meet user needs, most mobile terminals, such as mobile phones, tablet computers, cameras, etc., are equipped with a panorama camera function at present. [0003] The so-called panoramic photography is to take a plurality of continuous photos of a single scene, and stitch the plurality of photos to form a wide-angle photo. The existing panorama photographing method is: after the user takes the first photo in the panorama photograph mode through the mobile terminal, according to the prompts (such as arrows, straight lines, etc.) in the preview interface, move the mobile terminal horizontally (or vertically) , after accurately moving one or half the displacement of the preview interface, take a second photo. In the same way, after multiple photos are obtained continuous...
