Embodiment Construction

[0019] The specific steps of the method for segmenting an infrared image according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Such as figure 1 As shown, in some embodiments of the present invention, in step 10, a frame of infrared image data may be acquired. In an embodiment of the present invention, the frame of infrared image data can be the image data that the infrared imaging system has obtained and stored in the memory, and is read from the memory in step 10; it can also be the image currently acquired by the infrared imaging system in real time data.

[0021] In one embodiment, the acquired frame of infrared image data is as figure 2 shown.

[0022] In step 20, linear stretch processing may be performed on the frame of infrared image data, so as to obtain linear stretch image data.

[0023] For example, in one embodiment, the frame image data can be mapped to 0-2 14 Between, and...

Abstract

An embodiment of the invention discloses an infrared image segmentation method. The method comprises: obtaining a frame of infrared image data; performing linear stretch processing and histogram equalization processing on the infrared image data to obtain histogram equalization image data; performing clustering analysis on the histogram equalization image data to obtain a plurality of clusters; constructing a measure function, and obtaining a corresponding cluster when the value of the measure function is maximal from the clusters; calculating a threshold according to the corresponding cluster when the value of the measure function is maximal; and binarizing the infrared image data by using the threshold. The infrared image segmentation method provided by the embodiment of the invention is simple to operate and quick in clustering.

Description

technical field [0001] The invention relates to the technical field of uncooled infrared imaging, in particular to a method for segmenting infrared images. Background technique [0002] Infrared image threshold segmentation is the extraction of the region of interest, which is widely used in target detection. Infrared images are widely used in the detection of pedestrians at night, and the key to target detection in infrared images lies in the extraction of regions of interest. . [0003] Existing infrared image segmentation methods are usually complicated and slow. Contents of the invention [0004] One of the objects of the present invention is to provide a simple and fast method for segmenting infrared images. [0005] The technical solutions disclosed in the present invention include: [0006] A method for segmenting an infrared image is provided, comprising: acquiring a frame of infrared image data; performing linear stretch processing on the infrared image dat...
