AI Analysis & Value Prop
Currently, in the fisheries industry, accurate estimation of fish school density is crucial for resource management and fishery planning. However, traditional methods like manual observation and fishing records present issues of high cost, large error margins, and poor real-time performance. This dataset, based on sonar images, aims to enhance the accuracy and efficiency of fish detection, addressing the shortcomings of existing methods. Through this dataset, users can conduct image-based fish density analysis, achieving automated and precise fisheries resource management.The dataset is collected using sonar equipment in different fishery environments, with equipment installation depth and collection conditions carefully designed. Data quality is ensured through multiple rounds of labeling and review by a professional fisheries expert team, guaranteeing high precision and consistency. The labeling team comprises over 20 members with expertise in fisheries and image processing. Data preprocessing steps include noise filtering, image enhancement, and contrast adjustment, stored in JPG format, organized in categorized folders for easy retrieval and use.
