The invention relates to the technical field of underwater positioning, and discloses a shallow water target positioning system and method. The shallow water target positioning system comprises a water surface supporting platform, underwater operation equipment, a pull rope sensor, a first reference point and a space pose sensor, the pull rope sensor is arranged between the underwater operation equipment and the water surface supporting platform, and the first reference point is arranged at the water surface connecting part of the water surface supporting platform and the pull rope sensor. The water surface support platform is further provided with a space pose sensor for detecting the space coordinates of the first reference point, and the method comprises the steps that underwater operation equipment is arranged, and a space coordinate system is constructed according to connecting points; the length data of the pull rope sensor and the space coordinates of the first reference point are obtained, the coordinates of the underwater operation equipment are calculated according to the length data, the space coordinates of the first reference point and the space coordinates of the connecting point, and the coordinates of the underwater operation equipment can be rapidly and accurately obtained through the reference point and the positioning steel wire rope. The problem that underwater operation equipment in a shallow water area cannot be accurately positioned is solved.

    本发明涉及水下定位技术领域,公开了一种浅水目标定位系统及方法。浅水目标定位系统包括水面支持平台、水下作业设备、拉绳传感器、第一参考点以及空间位姿传感器,拉绳传感器设置于水下作业设备与水面支持平台之间,第一参考点设置于水面支持平台与拉绳传感器水面连接部分,水面支持平台还设置有检测第一参考点空间坐标的空间位姿传感器,方法包括:布放水下作业设备,根据连接点构建空间坐标系;获取拉绳传感器的长度数据、第一参考点的空间坐标,根据长度数据、第一参考点和连接点的空间坐标计算水下作业设备的坐标,通过参考点和定位钢丝绳可以快速精准的获取水下作业设备的坐标,解决了浅水区域水下作业设备无法准确获取定位的问题。
