Embodiment Construction
[0058] The method for automatic identification of military ships and civilian ships based on deep learning provided by the present invention will be further described below in conjunction with the accompanying drawings.
[0059] Aiming at the relevant technical problems existing in the prior art, this invention starts from the concept of intelligent recognition of military ships and civilian ships, and combines the most advanced technical means of deep learning in target detection, and proposes a target recognition method based on dense full convolutional neural network. This method can accurately detect military ships and civilian ships.
[0060] In order to solve the technical problems existing in the prior art, the present invention proposes an automatic recognition method for military ships and civilian ships based on deep learning——DRFCN2, specifically as figure 1 , including the following step (1): Generate as few high-quality sampling regions as possible through a regio...

Abstract
The invention discloses a military ship and civilian ship automatic identification method based on deep learning, and belongs to the field of automatic target identification based on the image. The method can be applied to the field of coast defence, weapon and equipment intellectualization and situation assessment. According to the method, an algorithm model of densely connected convolution layers is redesigned for the problems that all the layers of the conventional target identification network based on deep learning are unidirectionally connected and the feature expression capacity is insufficient. The algorithm model reuses the features of each layer by using the dense connection mode so that the target identification average accuracy of the algorithm model can be enhanced; the full connection layer of excessively high weight parameter is eliminated by the algorithm model by using the full convolution feature extraction mode, and the algorithm model trained by the mode is smaller;besides, the problems of gradient diffusion and gradient expansion can be solved by the algorithm model.
Description
technical field [0001] The invention belongs to the field of image-based automatic target recognition, and in particular relates to an automatic recognition method for military ships and civilian ships based on deep learning. Background technique [0002] Under the new situation, networked joint operations present the characteristics of land, sea, air, space, electromagnetic, and cyber multi-dimensional battlefield integration operations. Carrier, surface, underwater, ship mount, database system), multi-source sensors (SAR / ISAR, infrared camera, hyperspectral / multispectral / low light / EO / visible light, sonar, laser, millimeter wave) and other ways can obtain Massive image and video data, the data source has the characteristics of "5V+1C", namely: Volume (large capacity), Variety (diversity), Velocity (timeliness) and Veracity (accuracy), Value (value) and Complexity (Complexity). Therefore, it is particularly important how to find out the required military ships, civilian sh...
