Abstract

The invention relates to a device and method for locating an object by laser. The device includes a laser transmitter, a gyroscope, a laser receiver, a distance calculation module and a coordinate calculation module. The present invention uses the form of laser distribution function to realize the positioning of underwater targets for the first time, and is different from the traditional measurement method using transmission time or time difference in that it only uses the properties of laser transmission to measure, and uses the gyroscope to measure the connection direction of the target. Fine-tuning makes the measured distance data highly accurate, and can realize the positioning of targets at any distance within the effective range of laser transmission, with high positioning accuracy, convenient positioning, and low cost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a device and a method for locating an object by laser. Background technique [0002] When communicating with underwater targets, laser communication can be used to improve safety. [0003] The premise of laser communication is to be able to locate underwater targets. An existing device and method for locating an underwater target is to float the underwater target to a position close to the water surface, and then release the GPS receiver connected by a cable or optical fiber to make the antenna of the GPS receiver surface to receive GPS satellite signals to determine the location of underwater targets. [0004] The main problem existing in the above-mentioned prior art is that the positioning accuracy is not high. Because what is obtained by positioning is actually the position of the surface GPS satellite signal receiver, not the true position of the underwater target....
