摘要

摘要: 利用粒子群优化算法（PSO）较强的鲁棒性和全局搜索能力等优点，将PSO算法与BP神经网络相结合，优化了BP神经网络分类时的初始权值和阈值。基于珠江河口三角洲的侧扫声呐图像数据，提取了海底声呐图像中砂、礁石、泥3类典型底质的6种主要特征向量，利用PSO-BP方法对海底底质进行分类识别。实验表明，3类底质分类精度均大于90%，高于BP神经网络70%左右的分类精度，表明PSO-BP方法可有效应用于海底底质的分类识别。

Abstract: By combining Particle Swarm Optimization (PSO) with BP neural network, the initial weights and thresholds of BP neural network classification are optimized by utilizing PSO with strong robustness and global searching ability. Extracting six main feature vectors of sandy, rocks and mud in the seabed sonar images based on the data of side scan sonar in the Zhujiang Estuary Delta, using the PSO-BP method to classify seabed sediment. The experiment shows that the accuracy of the sediments classification is more than 90%, higher than the accuracy about 70% which using BP neural network only. It proves that the PSO-BP method can be effectively applied to the identification and classification of sediment seabed.
