Embodiment

[0108] Step 1: Obtain a to-be-processed infrared image f of size m×n 0 (x, y) for preprocessing, where f 0 (x,y)∈R m×n , As in figure 2 Shown

[0109] Step 2: The saliency detection algorithm based on global contrast processes the preprocessed image to obtain the saliency image f 2 (x, y), where f 2 (x,y)∈R m×n , As in image 3 Shown

[0110] Step 3: Convert the saliency image f 2 (x, y) are processed to get the candidate area g i (x, y), Specific as Figure 4 Shown

[0111] Step 4: The candidate area g i (x, y) Input the fine-tuned trained MobileNetV2 convolutional neural network one by one, and get the output result y i ∈R, according to the output result y i ∈R judge each candidate area g i (x, y) Whether it is a frozen lake, for example Figure 5 Shown.

[0112] In summary, after acquiring infrared images, the present invention first preprocesses the image to eliminate noise; then uses the saliency detection algorithm based on global contrast to obtain the saliency image; then com...

Abstract

The invention discloses an infrared imaging icing lake detection method based on MobileNetV2, belongs to the field of target detection in remote sensing and infrared image processing, and solves the problems that an existing detection method based on artificial design characteristics is poor in universality and low in robustness on various scenes. The method comprises the steps of obtaining a to-be-processed infrared image f0(x,y) with the size of m*n for preprocessing; processing the preprocessed image based on a global contrast saliency detection algorithm to obtain a saliency image f2(x,y);processing the saliency image f2(x,y) to obtain a candidate region gi(x,y); inputting the candidate regions gi(x,y) into the MobileNetV2 convolutional neural network subjected to fine tuning trainingone by one to obtain an output result yi belongs to R, and judging whether each candidate region gi(x,y) is an iced lake or not according to the output result yi belongs to R; the method is used fordetecting the iced lake through infrared imaging.

Description

Technical field [0001] An infrared imaging frozen lake detection method based on MobileNetV2, used for infrared imaging frozen lake detection, belongs to the target detection field in remote sensing and infrared image processing. Background technique [0002] Infrared imaging technology can realize target detection and recognition, has non-contact, strong ability to capture details, can realize long-distance detection and is not affected by obstacles such as smoke and fog, and can also realize continuous detection day and night. Therefore, in the military , Civil and other fields are widely used, especially the military value is extremely high. Among them, infrared target detection technology mainly uses the infrared radiation difference between the target and the background for target detection and recognition. In military early warning systems, infrared images generally have low contrast and blurry edges, and the presence of various false alarm sources (icing lakes, high-altit...
