Unmanned ship measurement method for underwater root stone of river regulation project

The invention discloses a river regulation project underwater root stone unmanned ship measurement method comprising the following steps: 1, in a 4G/5G network area, using a 4G/5G network to realize unmanned ship remote control; 2, in a region without a 4G/5G network, two-way communication is realized by arranging a radio station on the field land and an unmanned ship respectively, and an operator controls the detection data quality on a mobile vehicle; 3, the unmanned ship calculates the distance to the root stone through a laser radar range finder; and 4, in the process of approaching the shoreside in the root stone measurement, when the rotation angle of the measuring line is greater than 160 degrees, the unmanned ship is remotely controlled to reverse along the original measuring line for measurement, and when the distance from the original measuring line to the shoreside is equal to a set distance, the unmanned ship turns in situ and enters the next measuring line for detection work. The system is specia
