摘　　要：为了获取飞机起落架强度试飞在不同工况下的起飞前精确空间位置,起飞偏心量,滑跑速度等参数,为飞机起落架性能提供重要鉴定依据,采用一种基于单站相机的飞机起飞精确空间位置测量方法,以机上自身抽引惯导数据为约束条件,简化前方交会模型,将传统的多台相机交会测量变为单台相机测量,并与全站仪测量真值数据进行比较。分析结果表明,基于单站的测量方法测量精度优于2 cm,满足试飞任务需求。In order to obtain the precise spatial position,takeoff eccentricity,taxiing speed and other parameters of the aircraft before takeoff,and provide an important evaluation basis for the performance of the aircraft landing gear,a precise spatial position measurement method of aircraft takeoff based on a single station camera is adopted.Taking the inertial navigation data extracted by the aircraft itself as the constraint condition,the forward intersection model is simplified,and the traditional intersection measurement of multiple cameras is changed into a single camera measurement,which is compared with the total station measurement data.The analysis results show that the measurement accuracy of the measurement method based on single station is better than 2 cm,which meets the requirements of flight test mission.
