Problems solved by technology

Relying on manual inspection for color cast detection is not only time-consuming and laborious, but also prone to false positives. In addition, it is difficult to unify the subjective standards of people, which will also lead to lack of consistency in the alarm results.

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown, the present invention provides a method for detecting color cast of camera video, comprising the steps of: receiving multi-frame video; calling the video frame color processing method by frame to judge color cast for each frame in the video; synthesizing multi-frame video gray The grayscale value of the video can be judged; the color cast of the video can be judged by combining the color cast value of multiple frames of video. The present invention will be described in detail below.

[0024] Such as figure 1 As shown, after the computer receives the multi-frame video, it calls the video frame color processing method for each video frame of the multi-frame video, and performs color cast recognition processing on the video frames of the multi-frame video. Such as figure 2 As shown, the video frame ...

Abstract

The invention discloses a method for detecting camera video color cast. The method comprises the following steps: receiving a multi-frame video; judging the color cast of each frame in the video in a processing method of calling video frame colors according to frames; judging a gray level of the video by integrating a gray level of the multi-frame video; judging the video color cast by integrating a color cast value of the multi-frame video. By detecting the color cast failure of an image of the video, a set of quantitive detection indexes are established, the burden of human eye recognition can be alleviated, and errors caused by subjective judgment can be reduced.

Description

technical field [0001] The invention relates to a method for detecting video color cast of a camera, and belongs to the technical field of video image processing. Background technique [0002] With the continuous development of the economy, security equipment has gradually spread in every corner of people's lives. The scale of the video surveillance system is getting larger and larger, and the number of monitoring screens is also increasing. It is very inefficient to check the video screens one by one only by human eyes. Therefore, the importance of intelligent video fault diagnosis is increasingly prominent. [0003] Usually, due to the influence of factors such as ambient light source, reflective characteristics of the object itself, and the light sensitivity coefficient of the acquisition device, there is a difference between the color of the image captured by the image acquisition device and the color of the real image, that is, the color cast phenomenon. The reasons ma...
