RCS detection system based on binocular vision, and detection method thereof

Abstract

The invention discloses an RCS detection system based on binocular vision, and a detection method thereof. The system and the method can realize that during RCS detection, a detected object and a detection scene are subjected to three-dimensional reconstruction, a three-dimensional scene coordinate system is converted to be consistent with a world coordinate system, namely an RCS detection coordinate system, and an RCS detection numerical value is superposed with a reconstructed three-dimensional model, so the RCS characteristic value of the position of the measured object can be accurately checked. For example, a stealth aircraft is parked on a parking apron or a hangar, 360 DEG shooting is carried out around A stealth aircraft through a binocular vision camera, three-dimensional reconstruction of the stealth aircraft and the parking apron or the hangar is achieved, a three-dimensional model of a measured object is generated, meanwhile relevant coordinates of the stealth aircraft and the position of the stealth aircraft are generated, then the RCS detection value of the stealth aircraft in a world coordinate system is acquired, the RCS detection value and the three-dimensional model of the stealth aircraft are superposed through a computer, the condition of the stealth aircraft is analyzed, and related information is fed back.

Description

technical field [0001] The invention relates to the technical field of detection systems, in particular to a binocular vision-based RCS detection system and a detection method thereof. Background technique [0002] RCS is the most critical concept in radar stealth technology, which represents a physical quantity of the echo intensity generated by the target under the radar wave illumination. In layman's terms, RCS is the size of the area that the radar can see. [0003] After the radar is applied to the military, the scattering cross-sectional area of ​​the radar becomes one of the most important and basic parameters. In the 1950s and 1960s, in order to identify the true and false warheads of intercontinental missiles, and in the 1980s, due to the needs of stealth and anti-stealth technology for aircraft, there were two climaxes in the research of RCS. Since then, in view of the important value and significance of RCS, it has transitioned to the application of RCS technolo...
