Abstract

The invention discloses a sonar image recognition method and device, electronic equipment and a storage medium. The method comprises the steps of preprocessing a forward-looking sonar image data set, a multi-beam sounding sonar image data set and a side-scan sonar image data set; respectively constructing transfer learning models corresponding to the foresight sonar image data set, the multi-beam sounding sonar image data set and the side-scan sonar image data set, and performing training to obtain three groups of corresponding classification results; calculating the recognition rate of the three types of sonar image recognition results, and inputting the recognition rate into a D-S evidence decision theory algorithm to be fused into the three groups of sonar image recognition results to finally obtain the sonar image recognition device. According to the method, the three types of sonar image recognition results are recognized in a machine self-learning mode in a transfer learning mode; the dependence on the number of the sonar images is reduced; and the sonar image recognition result is improved.

Description

technical field [0001] The present invention relates to the technical field of sonar image recognition, in particular to a sonar image recognition method, device, electronic equipment and storage medium. Background technique [0002] In recent years, with the rapid development of economy and society and the needs of national infrastructure construction, the demand for the detection and identification of underwater minerals and seabed structures has increased rapidly. Using sonar image recognition technology, a large area of ​​underwater targets can be scanned and recognized to improve recognition efficiency. However, due to the few features of the underwater target data set, the recognition has always been difficult. The current common sonar technologies usually include forward-looking sonar, side-scan sonar and multi-beam sounding sonar. Forward-looking sonar is a kind of active sonar, which "focuses" the sound wave signal in a predetermined direction, that is, forms the d...
