Processing Method Research On Film About Aircraft Model Data

Based on the practice of plane model flying in the sky,this paper introduces a new measurement about how to measure the flight parameters of plane model. The measurement is taking two theodolites to observe the model and at the same time conserve the data about the model flying in the air, after that analyse the film to get the parameters.Because of the equipment and condition of observation, there are several central errors effect the precision of film data .This thesis provide the formulas to amend the errors . Especially, to the earth curvation effect the observation result,we establish the mathematical modeling . The film data can be restituted well and gotten a better precision .After film data amend, the intersection method between two theodolites is discussed also and analyse the precision of intersection method. Provide the matching arithmetic and make the simulation, the result indicate that it can meet measure demand.
