Dataset Name: Sonar Common Target Detection Dataset (SCTD) 1.0 Format: Pascal VOC with xml annotations. (voc2coco.py is also available) Authors:Dr. Peng Zhang,Dr. Mingqiang Ning, Zhisheng Zhang, Han Li, Yan Zhou, Prof. Yue Fan, Prof. Dandan Liu ...
Target signal acquisition and detection based on sonar images is a challenging task due to the complex underwater environment. In order to solve the problem that some semantic information in sonar images is lost and model detection performance is degraded due to the complex imaging environment, we...
Compared to Nao-Chatbot, the participants reported significantly higher scores for Nao-SONAR also in terms of feeling more comfortable with and better understood by the robot during interactions, and in terms of their perception of having something in common with the robot. The participants reported...
Detection/Classification task of SONAR signals, especially in the passive SONAR system, is one of the most challenging areas in this field. In passive SONAR system, received noises with SNR as low as -15dB are very common at the receiver (Urick 1983). Added reverberation and scattering, ...
Localization error boxplot for filter configuration “Sonar” over the whole dataset shows that the results are the least precise as it can be seen in Figures 8(a) and 8(b). This is a result of the fact that all the data is included, even the data when target is lost from the sona...
2.3Automatic target recognition problem in sonar images Automatic object detection and identification in sonar imagery is active research area in the Naval force, maritime for longer period. Due to enhancement in technology, threats to Naval, maritime have increased so new benchmarks for object identi...
single-target detection by lowering a standard copper sphere of known target strength (TS) below the transducer and moving it in a raster using a winch driven setup (Fig.S2). The system uses a split-beam configuration to obtain precise information on the sphere’s position based on phase ...
The side-scan sonar dataset (SSSD) used in this study consists of two parts: one part is sourced from the publicly available sonar common target detection dataset (SCTD) [24], and the other part was collected by our team using a USV equipped with a multi-beam and SSS collection system,...
By pre-training the large-scale Underwater Acoustic Target Detection Dataset (UATD dataset), DA-YOLOV7 obtains initial weights, fine-tuned on the smaller Smaller Common Sonar Target Detection Dataset (SCTD dataset), thereby reducing the risk of overfitting which is commonly encountered in small ...
When it comes to bathymetry data, Sonar is like our underwater eyes. Two of the most common bathymetric data sources are: GEBCO Bathymetry: The GEBCO Grid 2023 is the most recent global elevation grid. Using soundings and satellite-derived gravity data, it provides a resolution of 30 arc-sec...
