The descending speed of the aircraft is fast and the time is short. How to measure the instant descending speed has become a research hotspot. At the moment of descent, the on-board sensors and other equipment often have intermittent signals at the moment of landing, resulting in data gaps, which cannot meet the needs of actual scientific research. Based on this, a set of high-speed camera arrays is designed in this paper, and the camera angles are overlapped by cross-layout. The camera hardware is programmed to grant GPS time uniformly, which unifies the camera time. Then, the method of multi-eye vision measurement is used to measure the descending speed of the aircraft, and the simulation verification is carried out, and good results are obtained. Finally, the error is evaluated, and the measurement speed accuracy can meet the actual use, which shows that the establishment of the camera array measurement system can quickly and effectively solve the problem of aircraft descent speed measurement.
