摘　　要：针对海上沉船、空难等事故水下残骸搜索工作难的问题,提出一种基于图像声纳和差分GPS的水下残骸搜索和精确定位的方法,该方法单位时间内有效扫描面积较大,定位精度高,实用性强。Aiming at solving the difficulty of searching underwater wreckage of shipwreck and aircraft accident, an accurate searching and locating method is brought forward. Based on image sonar and differential GPS positioning technique, the method has the quality of large effective searching area in unit time and high precision. Compared with traditional ways, this new locating method is more practicable and efficient.
