Before integrating a new external store onto a fighter aircraft, a ground static ejection test is required to evaluate separation safety, identify potential collision risks, and collect engineering data required by MIL-HDBK-1763 for aircraft–store compatibility assessment, including store displacement, attitude, velocity, and ejection force during release from the pylon. This research develops a data acquisition system for ground static separation tests and collects key separation parameters specified in MIL-HDBK-1763 including ejection force, store attitude and displacement during release from the pylon. The system consists of a calibrated high-speed camera system, a ground ejection module and an in-house image processing software. The software performs stereo camera calibration, store displacement, velocity, attitude and ejection force estimation throughout the separation process. Experiments using an external fuel tank model ejected from an aircraft pylon show that the system can accurately capture and estimate states at 400 frames per second. The displacement error is 1 mm at a 1σ confidence level. The high-speed camera system uses commercial off-the-shelf hardware, resulting in a very low total cost. The use of commercial off-the-shelf hardware significantly reduces implementation cost compared with traditional military photogrammetry systems. The developed solution provides a practical and reliable tool for MIL-HDBK-1763-compliant static ejection testing and aircraft-store compatibility assessment.
