Marine weak and small moving ship real-time detection method based on deep learning

Abstract

The invention relates to a marine weak and small moving ship real-time detection method based on deep learning. The method comprises the steps: step 1, carrying out target detection processing on an image in a marine monitoring system video; step 2, performing size unification operation on the size of the input image; step 3, extracting small target features by using the first part of the networkstructure; and step 4, for the extracted features, learning the effective features of the small targets from the shallow network by using the classifier of the second part of the network structure, and then integrating the position information of the deep network to finally classify the small targets, wherein the network structure is of a full convolutional network type and comprises two parts, and the first part is used for extracting effective features of a target; and the second part is used for detecting a target and determining a final detection result.

Description

technical field [0001] The invention belongs to target detection and tracking technology, and in particular relates to an efficient detection method for weak and small targets in RGB color images with relatively single background and various infrared images. Background technique [0002] Object detection is a prerequisite for various advanced vision tasks and is widely used in various image processing tasks. Existing target detection technologies, such as face detection and pedestrian detection, have already had very mature application solutions. Relatively speaking, there is no very mature application solution for the detection of weak and small moving ships. Generally speaking, the target detection of weak and small moving ships is mainly used in the intelligent monitoring system. Due to the continuity of the monitoring system and the suddenness of the situation, manual monitoring cannot be vigilant at all times, which is prone to negligence and incalculable losses. Theref...

Problems solved by technology

Due to the lack of available information of the weak target image and its susceptibility to noise, the complex and changeable weather environment on the sea causes the line of sight to be blocked, etc., it is difficult for many recognition algorithms to achieve satisfactory recognition results, which seriously affects the reliability and reliability of the weak target detection system. practicability, so the research topic of real-time detection of weak and small moving ships at sea has great practical significance
