Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0041] like figure 1 As shown, a kind of panoramic camera color consistency evaluation method provided by the present invention comprises the following steps:

[0042] S1: Use each lens of the panoramic camera to shoot the images to be judged under different light sources;

[0043] In an embodiment of the present invention, the shooting environment of each lens of the panoramic camera and the shooting standard reference...

Abstract

The invention provides a system and method for color consistency judgment of a panoramic camera and belongs to the technical field of imaging processing. The method comprises a step S1 of utilizing each lens of a to-be-measured panoramic camera to shoot to-be-judged images under different light sources; and a step S2 of calculating a color grain straight line of each lens of the to-be-measured panoramic camera. In the system and method for color consistency judgment of the panoramic camera, by setting a color consistency detection environment of the panoramic camera, judgment images are collected, and color gain values of the judgment images are calculated, form a straight line and are shown visually in a picture form. From the picture, we can quickly and accurately describe whether the color consistency of the panoramic camera is good. In addition, the color deviation of each lens and lens light source color cast under different light sources are calculated, color consistency index parameters can be provided.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a panoramic camera color consistency evaluation system and method. Background technique [0002] A panoramic camera refers to the use of multiple cameras to shoot a space scene at the same time and output a 360-degree panoramic video in real time. A panoramic camera has at least two or more lenses, and the core technology is the real-time stitching of multiple videos. [0003] Due to the manufacturing defects of each lens in the panoramic camera, the images captured by the same lens have obvious color differences at different positions. In addition, there are also differences in color between different lenses, and the stitching of the panoramic camera to compensate for the color The difference between the algorithms finally leads to the problem of color consistency in the panoramic video output by the panoramic camera. Even if the scene captured by each len...
