Monocular 3D Video Extensometer
During takeoff, hovering, turning, and landing, a UAV undergoes continuous changes in position and attitude. Ordinary video alone allows the flight process to be observed, but makes it difficult to directly obtain motion trajectories, displacement changes, and attitude data suitable for analysis.

Haytham video extensometerBy identifying and tracking the marked points on the UAV body, position changes during flight can be continuously acquired. Based on the motion information of different marked points, the flight trajectory, direction of motion, displacement magnitude, and attitude changes of the UAV can be analyzed, and key maneuver phases can be recorded as data.
No cables need to be connected between the UAV and the measurement equipment during the test, which reduces the influence of contact measurement devices on the flight state. By synchronously tracking multiple marked points, the overall motion characteristics of the airframe during ascent, descent, turning, or vibration can also be determined, providing a basis for comparing different flight parameters and control strategies.
UAV dynamic tracking measurement can be used for flight control testing, airframe motion analysis, vibration testing, takeoff and landing process research, and control algorithm verification, and is also applicable to non-contact motion tracking of robots, mobile platforms, and other dynamic targets.
