According to the special requirement of minimum control speed flight test for civil planes,a stable photoelectric measuring system is designed in this paper to evaluate the departure distance from aircraft to runway centerline. A high?speed digital camera is mounted on the ventral centerline to obtain sequence images of runway and plane wheel of the running plane. With high?accuracy calibration of high?speed digital cameras and image processing,sub?pixels coordinates of the feature points on the wheel of front undercarriage and runway centerline are identified. The departure distance from aircraft to the runway cen?terline is calculated accurately according to the photogrammetry. The measurement result is analyzed in combination with the da?ta from actual flight tests,which shows the correctness of the measurement results.
