Background technology
In the attitude measurement technical field, the attitude measurement method of traditional sense mainly contains transit attitude measurement, obliquity sensor attitude measurement, digital compass attitude measurement and seeks northern instrument attitude measurement several.
1) transit attitude measurement: transit comprises pedestal, scale (horizontal dial and altitude circle) and three parts of alidade.Pedestal is used for supporting whole instrument.Horizontal dial is used for measuring horizontal angle.Telescope, level tube and reading device etc. are arranged on the alidade.
Must calibrate earlier before measuring, during calibration, at first transit is placed on the tripod, adjust the level of transit then, make entire equipment guarantee absolute horizontality.
2) obliquity sensor attitude measurement: obliquity sensor is to use principle of inertia to measure a kind of acceleration transducer at surface level pitch angle.When obliquity sensor was calibrated, the equipment tool that needs had test platform, horizontal revolving stage, and the price of these equipment tool can not be lower than 100,000 usually, and must carry out clear operation to obliquity sensor when measuring at every turn.
3) digital compass attitude measurement: digital compass is become with groups of acceleration sensors by the magnetometric sensor that detects the magnetic field of the earth, the course is measured in magnetic field by the magnetometric sensor induction earth, measure carrier at the variable quantity of pitching and roll direction by acceleration transducer, during measurement, need avoid calibrating on-the-spot magnetic interference as far as possible, need guarantee the abswolute level of correcting device simultaneously, in addition, because different local magnetic fields of the earth are different, just must calibrate again so whenever change a place, increase the complexity of surveying work.
4) seek northern instrument attitude measurement: seek northern instrument by measuring rotational-angular velocity of the earth, independently determine the real north value of appended carrier.Seek northern instrument and be not subjected to the interference of external magnetic field or other environment and influence, during measurement, the equipment tool that needs has horizontal revolving stage and pedestal.These equipment tool prices can not be lower than 100,000 yuan usually, and it is big to seek northern instrument volume and weight, the specific operation process complexity.
