Embodiment 1

[0018] The horizontal underwater detection and positioning method involved in this embodiment is realized in the underwater detection and positioning device, and its specific process includes the following steps:

[0019] (1) Equipment installation: check respectively the above water part and the underwater part of installing the underwater detection and positioning device, the underwater part is brought into the water area to be tested by the diver and the chassis 11 is fixedly installed on the water fixture, and then the distance The instruments in the measurement module and the angle measurement module are installed, leveled and rotated pre-processed to complete the adjustment and installation of the equipment.

[0020] (2) Underwater search: the diver controls the transducer 1 to search by manipulating the No. The personnel notifies the diver to fix the position of the transducer 1, then reads the angle parameter of the azimuth and calculates the coordinate value of the st...

Abstract

The invention belongs to the technical field of underwater searching and positioning, and relates to a level type underwater detection positioning method. The method specifically includes the steps of equipment installing, underwater searching, underwater distance measuring, angle measuring, underwater positioning and the like. A distance measuring module and an angle measuring module are used in cooperation to acquire distance parameters and angle parameters of structures to be measured or measuring points, and thus accurate positioning detection is achieved. The method can be applied to underwater searching of objects or structures within a wide range, distance and angle positioning is carried out on found structures or measuring points, and thus operation easiness and convenience and cost reduction are achieved while high accuracy and precision are ensured. The detection technology is simple and reliable in principle. An adopted device is simple in structure, convenient to move, good in determination effect and high in determination efficiency and has application environment friendliness.

Description

technical field [0001] The invention belongs to the technical field of underwater search and positioning, and in particular relates to a horizontal underwater detection and positioning method, which realizes the search and positioning of underwater objects or structures through the comprehensive cooperation of distance and angle measuring instruments including a level. Background technique [0002] Underwater detection and search technology is an important part of ocean observation technology and a component of ocean three-dimensional monitoring network. It is mainly used in underwater acoustic technology, underwater TV and photography technology, submersible and underwater robot technology, etc. At present, among the methods used by divers to search, detect and locate underwater, on the one hand, they directly use artificial visual methods to search, and use auxiliary equipment such as steel rulers and tape measures for positioning. There are limitations in accuracy and acc...
