Problems solved by technology

After the camera shoots, because the picture taken by the camera is black, there will be flashing white bright spots at this point, and the obtained background image contains a large number of pixels, and its brightness value is in a relatively unstable state. If it is not processed, it will It has a great impact on the foreground detection. If it is finely processed, the background modeling will be cumbersome and time-consuming.

Abstract

The invention discloses an infrared-image foreground detection method and infrared-image foreground detection equipment, and belongs to the technical field of data processing. The method includes: collecting N frames of infrared images without moving target interference to use the same as training images, and calculating an average brightness value of each frame of training image; analyzing an image brightness value of each pixel position, and obtaining distribution probability of the different brightness values by counting to obtain image background pixel position-brightness value distribution relationships; and carrying out foreground detection on a currently-collected infrared image according to the image background pixel position-brightness value distribution relationships to obtain aforeground graph of the currently-collected infrared image. Through background modeling, a relatively stable background region can be obtained, interference of moving objects or noises on a backgroundand subsequent foreground operations can be reduced, and the background can still be stably analyzed even in a case of strong infrared light for obtaining a precise foreground region.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a background modeling and foreground detection method suitable for strong infrared light conditions. Background technique [0002] In the process of image processing, it is often necessary to find the target of interest from a video or a series of pictures, and background modeling is required at this time. If strong infrared light is encountered during background modeling, due to the unevenness of the wall, the brightness will change continuously when the infrared light hits the prominent point. After the camera shoots, because the picture taken by the camera is black, there will be flashing white bright spots at this point, and the obtained background image contains a large number of pixels, and its brightness value is in a relatively unstable state. If it is not processed, it will It has a great impact on the foreground detection. If it is finely processed, the backgro...
