Single-event-camera-based 3D trajectory measurement method for high-speed moving targets

High-speed target three-dimensional (3D) trajectory and velocity measurement methods have important uses in many fields, including explosive debris rotating specimen tracking. The conventional approach a binocular system with two high-speed cameras to capture the target’s 3D motion information. Hardware cost for is high, accurately triggering several difficult. Event-based recently received considerable attention due advantages dynamic range, temporal resolution, power consumption. To address problems of camera synchronization difficulties, data redundancy, blur measurement, this Letter proposes method based on single-event four-mirror adaptor. particle flight process marker disc were measured proposed method, results show that can monitor operational state flying objects at very low hardware cost.
