Embodiment Construction
[0057] The solutions of the present invention will be described in detail below in conjunction with 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. Using the gradient operator method and the Hough transform method to detect and extract the sea antenna from the infrared video image, and using the sea antenna to segment the sea surface area from the video picture.
[0060] First, the gradient operator method is used to extract the sea antenna; the Sobel operator is used to detect the horizontal gradient to obtain the horizontal gradient g x , use the Sobel operator to detect the vertical gradient, and obtain 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 antenna is located, and thus extract the sea antenna;
[0061] At the same time,...
