1. UAV related R&D, application and standard research for ship survey

UAVs , which can be used to take photos of the hull structure and transmit HD images to the surface monitoring end in real time for surveyors to evaluate the hull structure condition, are particularly outstanding in reducing survey cost, improving survey efficiency and reducing the risk of working at high altitude.

CCS has conducted research on the development and application of intelligent UAV for ship survey and related standards. Such UAVs can be used for various ship survey scenarios and has significant advantages in dark and enclosed steel hull structures. Functions such as hovering with stability augmentation, autonomous obstacle avoidance, real-time transmission of ultra-high definition images and unlimited endurance in circumstances of "no satellite information, no illumination and strong magnetic field interference" have been realized.

The intelligent UAV for ship survey developed by CCS has been applied in the close-up survey of more than 20 oil tankers and chemical tankers.

Key technologies of intelligent UAV and standard development for ship survey:

(1) Standard for UAV Application in Ship Survey: the proposal of "Unified Requirements for Survey and Certification of UAV and Other RITs" has been adopted by IACS. The Guideline for Application of UAV in Survey has been formulated.

(2) UAV cabin environment perception and intelligent obstacle avoidance technology: UAV cabin environment high-precision perception and modeling method based on laser radar is proposed to achieve intelligent obstacle avoidance in circumstances of "no satellite information, no illumination and strong magnetic field interference", and ensure safe flight of UAV in complicated cabin environment.

(3) UAV autonomous fault tolerant navigation technology under complicated cabin environment: inertia/laser radar/magnetic sensor/barometric altimeter/ dynamic model multi-source information integrated method is proposed based on Federated Kalman Filter framework. Robust estimation of UAV pose helps to realize comprehensive high precision navigation of UAV under satellite denial environment.

(4) Integrated design of UAV for ship survey: integrated design of power supply, shooting, intelligent display control system, dynamics and structure for UAV is adapted and intelligent UAV suitable for ship survey is developed to address long working hours, serious electromagnetic interference in cabin, high quality requirement for close-up survey image and UAV flight safety under complicated environment.

      (5) Ship survey simulation and data reproduction technology based on virtual reality: A simulation and verification platform for UAV ship survey is designed, and functions such as UAV survey plan formulation, algorithm verification and survey image backtracking in cabin model are realized based on virtual reality technology.
