Problems solved by technology

[0003] At present, the evaluation of the consistency effect of the brightness and color of the panoramic camera adopts the method of direct observation with the naked eye. This judgment method based on subjective consciousness cannot be quantified.
It can be seen that there is currently a lack of a technology to evaluate the consistency effect of panoramic cameras in terms of brightness and color

Abstract

The invention discloses a method and a device for detecting consistency of a panoramic camera, which are used for the technical field of panoramic cameras. The method comprises the following steps of carrying out frame extraction on a video shot by the panoramic camera, wherein the video is shot under the environment that each camera of the panoramic camera is at the same brightness and faces to the same standard reference; obtaining a mean gray value of a video image obtained by frame extraction, respectively obtaining a difference between each obtained mean gray value and a gray reference value corresponding to the mean gray value and taking a sum of all differences as a brightness consistency index parameter; obtaining a color value of the standard reference shot by each camera in the video image obtained by frame extraction and a mean square error of a color reference value corresponding to the color value, and taking a sum of all mean square errors as a color consistency index parameter. According to the method and the device, a consistency effect of the panoramic camera in the aspects of brightness and color can be effectively evaluated and quantized.

Description

technical field [0001] The invention relates to the technical field of panoramic cameras, in particular to a method and device for detecting consistency of panoramic cameras. Background technique [0002] At present, panoramic cameras have gradually become popular, the core of which is real-time multi-channel video stitching. The panoramic camera has at least two cameras. When the environment seen by each camera is different, due to the difference in the lighting and color of the camera itself, and the difference between the stitching algorithms that compensate for brightness and color, Finally, the output panoramic video has the problem of inconsistent brightness and color. Even if the environment seen by each camera is the same, the panoramic video output by it will have inconsistent brightness and color. [0003] At present, the evaluation of the consistency effect of the brightness and color of the panoramic camera adopts the method of direct observation with the naked...
