Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0026] The invention discloses a method for eliminating the difference in brightness and chromaticity of a panoramic image, which is used for a panoramic image composed of multiple pictures, such as figure 1 shown, including the following steps:

[0027] A. Obtain parameter values ​​of brightness and chromatic aberration of each picture forming the panoramic image respectively;

[0028] B. Calculate the average value of the obtained parameter values ​​of brightness and color difference to obtain the mean value of brightness and the mean value of color difference;

[0029] C. Adjust the brightness value and color difference value of each picture constituting the panoramic image respectively according to the brightness average value and t...

Abstract

The invention discloses a method and system for eliminating luminance and chromaticity differences of a panoramic image. The method and system are used for the panoramic image composed of a plurality of pictures. The method comprises the following steps: A, respectively obtaining luminance and chromaticity parameter values of the pictures forming the panoramic image, B, calculating the mean value of the obtained luminance and chromaticity parameter values to obtain the luminance mean value and the chromaticity mean value, C, respectively adjusting the luminance values and the chromaticity values of the pictures forming the panoramic image according to the luminance mean value and the chromaticity mean value, and displaying the panoramic image after the adjustment is finished. By the adoption of the method and system, the panoramic image can be more clearly, the sense of pictures is stronger, and a user can conveniently check the panoramic image clearly.

Description

technical field [0001] The present invention relates to the field of vehicle equipment, in particular to a method and system for eliminating brightness and chromaticity differences of panoramic images suitable for optimizing vehicle display equipment. Background technique [0002] Vehicle-mounted devices (such as panoramic parking systems) for capturing panoramic images on the market generally use multiple camera devices to capture shots, and then splicing the captured multiple lens images into a panoramic image. In the actual use of this vehicle-mounted device for capturing panoramic images, due to differences in the brightness and color difference of the lenses captured by each camera device, if multiple lens images with different brightness and chromaticity are directly stitched into a panoramic image , it will cause some places in the spliced ​​image to be very bright, some places to be very dark, the display is not clear, the image quality is poor, and it is difficult t...
