Embodiment 1
[0032] see figure 1 The color correction method for a panoramic image provided in Embodiment 1 of the present invention includes the following steps: It should be noted that, if there are substantially the same results, the color correction method for a panoramic image of the present invention does not use figure 1 The flow sequence shown is limited.
[0033] S101. Acquire a first fisheye image and a second fisheye image.
[0034] Specifically, the first fisheye image and the second fisheye image may be acquired by a fisheye camera or an electronic device with a fisheye lens.
[0035] S102. Expand the first fisheye image to obtain a first image, and expand the second fisheye image to obtain a second image.
[0036] Specifically, the first image and the second image may be respectively expanded according to internal parameters, external parameters, and distortion parameters, which are not limited here.
[0037] S103. Calculate an overlapping area between the first image and ...
Embodiment 2
[0072] see figure 2 The color correction device for a panoramic image provided in Embodiment 2 of the present invention includes:
[0073] An acquisition module 201, configured to acquire a first fisheye image and a second fisheye image;
[0074] The expansion module 202 is used to expand the first fisheye image to obtain a first image in RGB color space, and expand the second fisheye image to obtain a second image in RGB color space;
[0075] Calculation module 203, for calculating the overlapping area of the first image and the second image;
[0076] The first conversion module 204 is used to convert the first image and the second image from the RGB color space to the Lab color space;
[0077] The first adjustment module 205 is configured to adjust the brightness of the first image and the second image to reduce the brightness of the first image and the second image according to the brightness mean value of the first overlapping region and the brightness mean value of t...
Embodiment 3
[0082] Based on the same inventive concept, Embodiment 3 of the present invention provides a computer-readable storage medium, the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the implementation as provided in Embodiment 1 of the present invention is realized. Steps of a color correction method for panoramic images.

Abstract
The invention is suitable for the field of panoramic images, and provides a color correction method of the panoramic image, a device thereof and electronic equipment. The method comprises the steps ofacquiring a first fisheye image and a second fisheye image; respectively expanding the first fisheye image and the second fisheye image for obtaining a first image and a second image of an RGB colorspace; calculating overlapping areas between the images; converting the first image and the second image from the RGB color space to a Lab color space; in the Lab color space, adjusting brightness ofthe first image and brightness of the second image; converting the first image and the second image from the Lab color space to the RGB color space; according to the mean color value of a first overlapping area and the mean color value of a second overlapping area, adjusting the color value of the second image through using the first image as a reference, or adjusting the color value of the firstimage through using the second image as a reference. Obviously, the color correction method, the device thereof and the electronic equipment can realize smoother transition of the spliced panoramic image and higher vividness in view.
Description
technical field [0001] The invention belongs to the field of panoramic images, and in particular relates to a color correction method, device and electronic equipment for panoramic images. Background technique [0002] With the development of science and technology, the application of panoramic images is becoming more and more popular. The panoramic images can provide a 360-degree panorama, giving users an immersive experience. Generally speaking, a panoramic image is stitched from two or more photos, but due to the influence of the environment, there may be great differences in brightness and color between the photos, which leads to the stitching traces of the stitched panoramic image being very Obviously, it looks unnatural, so color correction is a key in the panoramaimage stitching process. Contents of the invention [0003] The object of the present invention is to provide a method and device for color correction of a panoramic image, a computer-readable storage med...
