Research on the scheme of missile trajectory measurement system based on photogrammetry

According to the flight test requirements, it is necessary to employ the photogrammetry method in the bomb cabin. The high-speed camera should be installed at the appropriate position within the bomb cabin for binocular stereoscopic rendezvous measurement. This will enable testing of weapon projection at different altitudes of the aircraft and facilitate detection of separation process, speed, and attitude of ejection weapons within the weapon cabin. In order to assess accuracy of the airborne high-speed image test system and ensure scientific rigor during type test flight, this paper proposes a theoretical analysis method for measuring accuracy of such system. Additionally, two measurement schemes are designed for front wall installation and side wall installation in the bomb bay respectively. Furthermore, missile body separation tests are simulated in a design laboratory to verify accuracy of proposed measurement scheme for airborne high-speed image measurement system. Experimental results demonstrate that installing a high-speed camera on the side wall of the bomb cabin yields higher measurement accuracy and can be applied effectively in subsequent test flights for scientific research models.
