Measuring Center of Gravity of Pilot Helmet Based on Binocular Vision

A variety of functions are integrated into the pilot helmet, making it an intelligent weapon platform for pilots to improve situational awareness and target attacks capabilities. However, the mass distribution of the helmet has also been changed, which has a negative impact on the pilot's health and safety. Accurate measurement of the Center of Gravity (CG) of pilot helmet is of great significance for the ergonomic design. Benefiting from the rapid development of 3D computer vision technology, a 3D coordinate of CG measurement scheme for pilot helmet based on binocular vision is proposed by adopting suspension method. The measuring equipment and program are introduced in detail, and the calculation model for the center of gravity is also established. The calibration results show that the proposed measurement scheme based on binocular vision is effective.
