Problems solved by technology

For example, in terms of ship segmentation, since there are many interference items in the near-shore environment, such as the segmentation of the coast and the sea area may be irregular, there may be interference objects such as islands in the sea area, and the brightness

Example Embodiment

[0057] The solution of the present invention will be described in detail below with reference to the drawings and embodiments.

[0058] A ship detection and tracking method based on infrared video, as shown in the figure, the steps are as follows:

[0059] Step 1. Use the gradient operator method and the Hough transform method to detect and extract the sea antenna from the infrared video image, and use the sea antenna to segment the sea area from the video image.

[0060] First, use the gradient operator method to extract the sea antenna; use the Sobel operator to detect the horizontal gradient, and obtain the horizontal gradient g x , Use the Sobel operator to detect the vertical gradient, and get the vertical gradient g y ;according to Calculate the total gradient g, sum the gradient g of each row of the image, the row with the maximum value is the row where the sea-sky-line is located, and the sea-sky-line is extracted;

[0061] At the same time, use the Hough transform method to e...

Abstract

The invention relates to the technical field of ship detecting and tracking, in particular to a ship detecting and tracking method based on an infrared video. The method comprises the following steps: detecting and extracting a sea-sky line through a gradient operator method and a Hough transformation method, and segmenting a sea area from a video picture using the sea-sky line; extracting the foreground of an infrared video based on an improved ViBe algorithm, extracting a suspected target from the sea area of the video, and repairing an extracted image; analyzing the texture features of the image based on a statistical histogram, and capturing the target; and tracking the moving target through a MeanShift algorithm based on multiple features and saliency detection. The video picture is segmented, search is carried out in the sea area alone, and the search scope is reduced. Through background subtraction based on the improved ViBe algorithm, the influence of island and shore background can be eliminated. By capturing the target based on a statistical histogram, the accuracy of target capture is improved. Target tracking based on the MeanShift algorithm is fast.

Description

technical field [0001] The invention relates to the technical field of ship detection and tracking, in particular to a ship detection and tracking method based on infrared video. Background technique [0002] As the main body of maritime transportation and an important military target, the automatic detection and identification of ships has very important practical significance. With the rapid development of earth observation technology, satellite remote sensing images can provide a very rich data source for ship target monitoring. At present, most research on ship detection based on remote sensing images is carried out around SAR (Synthetic Aperture Radar) images, while there are few researches on ship detection and tracking technology based on infrared video. In fact, infrared video detection and tracking technology is relatively mature in other fields, but there are still many problems in using it directly in ship detection. For example, in terms of ship segmentation, s...
