Embodiment

[0123] (1) Deep learning architecture

[0124] Object recognition based on deep learning outperforms traditional machine learning with matching big data. Deep learning is a convolutional neural network (CNN) that has deep layers consisting of convolutional, round-robin, and fully-connected layers.

[0125] The most commonly used structure of neural network is figure 2 As shown, it consists of three layers, called input layer, hidden layer, and output layer, and each layer consists of one or more nodes represented by small circles. Narrow lines between nodes indicate the flow of information from one node to the next. The output layer has four nodes, four classes in the case of object classification. The nodes in the hidden and output layers are called active nodes, while the nodes in the input layer are called passive nodes. Every value from the input layer is copied and sent to all hidden nodes. Known as a fully interconnected structure. Such as image 3 As shown, the ...

Abstract

The invention belongs to the technical field of underwater robots, and discloses an underwater robot target tracking method based on deep learning and monocular vision, which comprises the following steps of inputting the images from a video sequence, estimating an underwater transmission map by using a deep learning neural network for each input image, and determining a target orientation; and establishing a direction and a control scheme of the target motion estimation through a transmission graph obtained through a network. According to the novel underwater robot monocular vision target tracking method based on deep learning, the transmission of an underwater image is calculated by a monocular image acquisition method in an underwater environment. For each incoming video frame and an environment without the priori knowledge, a previously trained convolutional neural network is creatively introduced to compute a transmission map, which provides the depth-dependent estimation. According to the method provided by the invention, the target area can be found, and a tracking direction is established.

Description

technical field [0001] The invention belongs to the technical field of underwater robots, in particular to an underwater robot target tracking method based on deep learning and monocular vision. Background technique [0002] Currently, the closest prior art: [0003] Underwater robots have been widely used in various underwater tasks, such as maintenance and inspection of underwater structures, installation of sensors, and sample retrieval for scientific exploration, etc. These tasks are usually performed by human-controlled remote control, so operations rely on human perception (mainly Vision), the operating conditions, experience and skills of the operator seriously affect the quality of operation. Therefore, in order to ensure the accuracy of underwater work, automatic control is required, and high-precision underwater target tracking is a key requirement. [0004] There are many attempts to use vision sensors for underwater navigation, however, the proposed navigation ...
