Problems solved by technology

At present, the ship target detection on the sea surface is mainly detected in the sea-sky junction area in the image, and only the segmentation method is used to extract the ship target in the sea-sky junction area, thus limiting the range of the target detection area, and the extracted ship target is incomplete, resulting in detection No ship target or detected ship target is incomplete

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 Shown is the flow chart of the method of the present invention.

[0032] A sea ship target detection method based on the combination of row and column mean segmentation and contour growth. First, the method based on Hough transform is used to detect the sea antenna; then, the left, right, top and The lower boundary, so as to determine the region of interest; further, apply the method based on the combination of row and column mean segmentation and contour growth to segment the region of interest; next, calculate on the grayscale image and binary image corresponding to the region of interest The characteristics of the suspected target, and determine the effective ship target through feature discrimination.

[0033] 1. Use the method based on Hough transform to detect the sea antenna, the specific steps are as follows;

Abstract

The present invention relates to a kind of sea surface warship target detection method, obtains the left, right, upper and lower boundaries of interest area by calculating the quantity sum of vertical edge points on Sobel vertical edge map, thereby determines interest area; Based on row and column mean value The method of combining segmentation and contour growth is used to segment the image of the region of interest; the features of the suspected target are calculated on the grayscale image and binary image corresponding to the region of interest, and the effective ship target is determined through feature discrimination. The invention has wide adaptability to scenarios and accurate detection rate, and has very important significance and value.

Description

technical field [0001] The invention relates to the field of image target detection, in particular to a sea surface ship target detection method. Background technique [0002] Image target detection is an important branch of pattern recognition, and it is widely used in the fields of transportation and national defense security. As an important means of navigation and transportation, ships at sea have high economic and strategic value. Especially in the situation where marine resources are increasingly tense and lead to local conflicts, controlling the target of ships is an important means to effectively and quickly control the conflict situation. At present, the ship target detection on the sea surface is mainly detected in the sea-sky junction area in the image, and only the segmentation method is used to extract the ship target in the sea-sky junction area, thus limiting the range of the target detection area, and the extracted ship target is incomplete, resulting in dete...
