Research On The Noncontact Measurement System With CCD For Positional Relationship

To loading missiles on the emissive vehicle automatically, the positional relationship between the emissive vehicle and loading vehicle must be acquired.With the development of Single Chip Micyoco - SCM, Charge Coupled Devices -CCD - are used widely in the field of noncontact position measurement. But for the noncontact position measuring systems that are used interiorly or overseas, some can't acquire both the distance parameters and the angle parameters, others are very complicated because of the using of more than one CCD detectors.A noncontact 3-D position measurement system is introduced in this thesis. The system is composed of a planner array CCD detector, real time image analysis and quick data calculation system, which can survey the positional relationship between the haloid lamp objects on the emissive vehicle and the measuring system on the loading vehicle. The principle of the measurement is discussed and the parameter calculating equation is derived. At last, with the knowledge of trigonometry and error theory, the measuring precision of the system is analysed.
