A perception system based on LiDAR technology is designed to address the safety hazards of data transmission in the perception system of unmanned measurement ships during surveying operations. The perception system combines laser radar sensors, industrial control computers, and ethernet, and uses standard buses such as RS232 and RS485 to transmit data to the industrial control computer. The collected data is processed, and the feasibility of laser radar technology in the perception system is verified through experiments. At the same time, the key technologies and sensor working principles in the perception system were analyzed, and the data collected by the LiDAR was processed, ultimately obtaining the application method of LiDAR technology in the unmanned measurement ship perception system. The results indicate that the use of LiDAR technology in the unmanned measurement ship perception system is safe and reliable in its transmission process, effectively improving the security of information transmission in the unmanned measurement ship perception system during surveying and mapping operations.
