Abstract

The present invention belongs to the field of underwater search positioning technology, and relates to an underwater search positioning detection method. The method includes the steps of equipment installation, underwater search, underwater distance measurement, angle measurement and underwater positioning, employs a transducer to realize distance measurement of a structural object to be detected or a detected point, and employs an electronic compass to directly read parameters so as to realize angle measurement of the structural object to be detected or the detected point. The method not only can be applied to underwater object and structure search within a wide range, but also can perform distance and angle positioning on a searched structural object or detected point; the method has the characteristics of simple, scientific and reasonable detection process principle, high detection accuracy, simple equipment structure, convenient movement, great detection effect, high measurement efficiency and friendly application environment.

Description

Technical field: [0001] The invention belongs to the technical field of underwater detection, and specifically relates to a detection method for underwater search and positioning, which uses a single-beam ultrasonic measurement method to measure distance parameters, and uses an electronic compass to measure angle parameters, so as to realize the search and positioning of underwater structures or measuring points . 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 positio...
