Embodiment 1

[0045] The invention provides a target search method for infrared images, specifically as figure 1 shown, including the following steps:

[0046] S1. Obtain an infrared image, and perform image enhancement preprocessing on the infrared image to obtain the first layer of the image feature pyramid.

[0047] The infrared image reflects the temperature distribution of the image, and the general tracking targets are objects with obvious differences in temperature and surrounding environment. In order to make the target more obvious, for the infrared image, image enhancement is helpful to the realization of the follow-up tracking algorithm.

[0048] In this embodiment, the infrared image is a single-channel 8bit image, and the pixel value of the image is x in , the enhanced preprocessing of the infrared image includes: traversing the image, enhancing the gray value of each pixel, and the output pixel value is x out :

[0049]

[0050] Among them, k is the enhancement ratio, w...

Abstract

The invention provides a target searching method for an infrared image, and belongs to the field of image processing. The method comprises the steps: obtaining the infrared image, and carrying out the image enhancement preprocessing of the infrared image to obtain a first layer of an image feature pyramid; manually marking a target position on the infrared image, namely giving a target frame of a first frame; and extracting images of different layers in the target frame on the infrared image by using a feature pyramid algorithm: carrying out target search on each layer by using an SSDA template matching algorithm, frame-selecting the maximum possible position of the target, and recording confidence and target movement position information to obtain a search target. According to the method, the image feature pyramid algorithm is utilized, so that the search speed is increased, the frame rate is improved, it is guaranteed that effective features of the target can still be saved when the scale of the target changes, and real-time accurate search can be conducted on the infrared image of the moving background.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a target search method for infrared images. Background technique [0002] With the development of intelligence, images have become an important means of obtaining information. In image acquisition, image processing is a very important link. Image processing technology has been widely used in various fields such as industrial safety and medical management. Among them, in image processing, searching for specific objects from moving objects is a very important step in image processing. [0003] When searching the infrared image of the moving background in real time, it is necessary to lock the range to search and acquire the target as soon as possible, all of which are based on the processing of the infrared image. In the above situation, the amount of image data is large, and it is difficult to accurately search for the target by traditional image processing methods. ...
