摘要
针对大江大河水流环境下的水下工程平面精确定位难题,进行水下工程平面测量定位系统应用性研究。将水下电视技术和多阵元基阵的短基线水声定位技术相结合,解决了传统水声定位精度低的问题。采用多基元短基线定位方法进行快速定位检测,搜寻并确认目标,处理、记录、显示成果,获得了满足工程精度要求的水下平面定位系统,保证了水下工程的质量。
Aiming at the difficulty in accurate plane positioning of underwater projects in large rivers, a study was performed on the application of plane measurement and positioning system to underwater projects, The combination of video technology with the short baseline acoustic positioning technology based on multi-array-elements base overcame the low precision of the conventional acoustic positioning. By adoption of the short baseline positioning method of multi-base dements for rapidly positioning, detecting, searching and determining the objects, and software for processing, recording, and displaying the result, an underwater plane positioning system which could meet the requirement of engineering precision was obtained, and the quality of underground projects was ensured.
