Embodiment 1
[0049] see figure 1 , which shows a panorama stitching method provided by the present invention, including:
[0050] Step 101, acquire multiple pictures to be spliced.
[0051] In the actual application process, the user can continuously obtain multiple pictures through the terminal device, so that the scenes that the user wants to take pictures can be taken in batches by shooting different angles respectively. For example, the panorama that the user wants to take is as figure 2 As shown, at this time the user takes multiple shots figure 2 The partial image method that batches will be figure 2 The image is captured, such as image 3 As mentioned above, the present invention acquires the graphs S1, S2, S3, S4, S5, S6, S7, S8 and S9 in batches. At this time, pictures S1, S2, S3, S4, S5, S6, S7, S8 and S9 are pictures to be spliced.

Abstract
The invention provides a panoramic image splicing method. The panoramic image splicing method includes the steps that a plurality of images to be spliced are obtained, and the correcting coefficient of each image is calculated through a global optimization function, wherein the correcting coefficients correspond to the images one to one; colors of the images are corrected according to the correcting coefficients, the corrected images are spliced to be a panoramic image, and the spliced panoramic image is output. In this way, the colors of all the images are corrected before splicing of the panoramic image is carried out, the color difference between the images is reduced, splicing marks are eliminated, and the images can be better spliced dynamically. Color correction of the images is not limited between two adjacent images, the correcting coefficient of each image is calculated through the global optimization function, then the colors of the images are corrected according to the corresponding correcting coefficients, integrality of the overall to-be-spliced sequence of the images is fully taken into full consideration, and unnatural color smooth transition is avoided.
Description
technical field [0001] The present invention relates to the technical field of panorama stitching, and more specifically, to a panorama stitching method and a terminal device. Background technique [0002] The panorama photography technology is more and more favored by the majority of users. When the panorama photo is taken, after the terminal acquires multiple pictures, it splices the acquired multiple pictures, and finally outputs a complete panorama. [0003] In the actual panorama shooting process, because the exposure and white balance are set to automatic mode when the terminal captures the picture, and due to the uneven lighting of the shooting scene or different shooting angles, it is easy to cause large colors in the pictures obtained by taking pictures. difference. However, if the obtained multiple images are directly stitched without further color correction, obvious stitching marks will appear in the final output panorama, which will affect the user's use effect...
