Stroboscopic stripe detection and elimination method and device, camera equipment and storage medium

Abstract

The invention discloses a stroboscopic stripe detection and elimination method and device, camera equipment and a storage medium, which are used for detecting stroboscopic stripes of an image picture and improving the detection precision, thereby facilitating elimination of the stroboscopic stripes. The method comprises the following steps: acquiring a preprocessed initial image; carrying out binarization processing on the preprocessed initial image to obtain a binarized image; integral projection of the binary image in a preset direction is calculated, and a one-dimensional discrete signal is obtained; determining an effective wave crest and an effective wave trough in the one-dimensional discrete signal, wherein the effective wave crest and the effective wave trough are wave crests and wave troughs meeting preset effective conditions; and determining the stroboscopic state of the image according to the effective wave crests and the effective wave troughs.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a stroboscopic fringe detection and elimination method, device, imaging device, and storage medium. Background technique [0002] Image flicker, also known as power frequency flicker and power-line flicker, is a common physical phenomenon when the camera shoots and records videos under the AC light source environment. When stroboscopic occurs, alternating light and dark and moving stripes will appear in the image screen, which will seriously affect the image quality and bring about a bad user experience. [0003] In order to eliminate or suppress stroboscopic images, it is first necessary to accurately and reliably detect stroboscopic phenomena. In the prior art, it is usually determined by calculating the difference vector whether there is stroboscopic phenomenon in the current image frame; [0004] However, the method in the prior art can only achieve ...

Problems solved by technology

[0004] However, the methods in the prior art can only achieve relatively accurate stroboscopic detection in some specific scenes. In the face of some complex scenes, especially in scenes such as weak flickering of the light source, shaking of the picture, or occurrence of striped motion textures, the prior art The method is prone to false detection or missed detection, which will lead to the elimination or suppression of stroboscopic at the wrong moment, which will also have a great impact on the imaging quality
