Embodiment Construction
[0023] The present invention will be further described below in conjunction with accompanying drawing.
[0024] Such as figure 1 As shown, when the seabed exploration and rescue work are to be carried out, the AUV dives into the seabed, and sensors such as side-scan sonar start to work. Using the sonar-based self-propelled self-propelled seabed exploration and rescue search method of the present invention includes the following steps:
[0025] Step 1: The AUV dives into the seabed, and the side-scan sonar works to collect image features of the seabed.
[0026] Step 2. Perform dimensionality reduction processing on the high-dimensional submarine sonar detection image data:
[0027] Use the bag of words BoW (Bag of Words) local feature expression model to describe the seabed detection image to meet the rapid response ability to massive observation information;
[0028] First, the SURF (Speeded Up Robust Features) algorithm is used to extract the submarine vocabulary vector fro...

The invention relates to a sonar-assisted self-propelled seabed exploration and rescue search method, which belongs to the technical field of self-propelled seabed exploration and search strategies, and mainly solves the current search method for seabed exploration and rescue, which can only search for a predetermined target area and cannot be completed Problems with exploration and search of other search areas than the target area. The invention includes the following steps: AUV dives into the seabed, side-scan sonar works, and collects seabed image features; performs dimensionality reduction processing on high-dimensional seabed sonar detection image data; respectively calculates feature salience rates of sonar images on both sides; compares sonar images on both sides The saliency rate of the image; make a decision based on the comparison result and go to step one for the next step of region exploration. The invention realizes the AUV to autonomously and actively detect and search the seabed, overcomes the blindness in traditional exploration and search strategies, and provides a feasible solution for using the AUV with artificial intelligence to carry out seabed exploration and rescue.
Description
technical field [0001] The invention relates to a sonar-assisted self-propelled seabed exploration and rescue search method, and belongs to the technical field of self-propelled seabed exploration and search strategies. Background technique [0002] The current popular search methods for seabed exploration and rescue are mainly to plan the navigation route of the underwater vehicle in advance for the target area, so that the underwater vehicle can complete the seabed exploration and search and rescue according to the established route. However, this search method can only search for the predetermined target area, and cannot complete the exploration and search of other search areas other than the target area, and it has obvious human intervention when realizing the exploration and search of a larger area Sex and aimlessness, a great waste of manpower and material resources, shows the limitations and non-intelligence of current seabed exploration and search strategies.
