Problems solved by technology

[0004] The identification of real and false targets in the air is one of the key technologies in the infrared imaging guidance system. The aircraft and the decoy (disruption bomb) are very similar in their shape and motion state. The features of the target and the decoy are extracted based on the method of neural network recognition to analyze the image information. The utilization rate is not high

Embodiment Construction

[0027] Taking the identification of an aircraft as an example below, the present invention is further described, and the whole identification process is as follows: figure 1 shown.

[0028] 1. Determination of aircraft candidate areas

[0029] 1. Adopt the visual detection scheme based on thermal infrared camera, specifically, use thermal infrared imaging equipment to receive the thermal radiation of different objects in the attack area, realize the detection and imaging of objects, and obtain the original image.

[0030] 2. Use matlab to preprocess the original image, specifically through image acquisition in matlab to preprocess the image:

[0031] (1) Obtain the grayscale histogram, color histogram and HSV matrix of the original image through matlab, and save them in the form of parameters respectively. Among them, the gray histogram is to facilitate the digital acquisition of image brightness distribution. It is a two-dimensional image and is directly stored in the param...

Abstract

The invention relates to an infrared image detection method based on ROI and belongs to the image identification field. The infrared image detection method based on ROI comprises steps that S1, target candidate region determination, a significance detection method and a construction evaluation index are utilized to select multiple ROI regions most possibly containing a target from an original image; S2, target identification for the ROI regions, characteristic extraction for each ROI region possibly containing the target is carried out to acquire a characteristic vector of the ROI region possibly containing the target; the characteristic vectors of the ROI regions possibly containing the target are inputted to a classifier for comparison, and the ROI region containing the actual target is lastly acquired. The method is advantaged in that the method can be applied to a guidance weapon to facilitate the guidance weapon to more precisely distinguish the target from baits, and a missile is led to realize accurate strike.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to an infrared image detection method based on ROI. Background technique [0002] Modern warfare has higher and higher requirements for informatization, requiring guided weapons to have the characteristics of high precision, high intelligence, strong anti-interference ability and light miniaturization, and can detect in all-weather, all-weather, strong interference and complex background environments Aim and hit the target with precision. Infrared guidance technology is widely used in today's precision guidance technology. It is one of the main applications of infrared technology in the military. It plays a very important role in various arms and weapons. In addition, infrared imaging has multi-target panoramic observation, identification and tracking capabilities, and can realize intelligent guidance of thermal imaging to targets. [0003] Infrared guidance is divided into infrar...
