摘要：Today.CCD.linear. array. scanners.are.widely.used.on. satellite,. airborne.and.helicopter.platforms. to.provide. images.with.along.track stereo.viewing..For.the.orientation.of.this.kind.of.imagery,.models.based.on.the.rigorous.description.of.the.acquisition.geometry,.on rational.polynomial.functions.or.on. affine.transformations. are. used.. An. overview. is. presented.. Among. these.approaches,. the. model developed. at. the. Institute. of. Geodesy. and. Photogrammetry. (IGP),. ETH. Zurich,. belongs. to. the. class. of. rigorous. models. and. is applicable.to.a.wide.class.of.pushbroom.sensors.carried.on.satellite,.airplane.and.helicopter..The.model.can.be.used.with.single-lens and.multi-lens.sensors.with.synchronous.and.asynchronous.stereo.acquisition..The.sensor.position.and.attitude.are.modelled.with.2 nd order.piecewise.polynomials.depending.on.time..Additional.pseudo-observations.allow.the.reduction.of.the.polynomial.order.from.2 to.1.if.the.trajectory.allows.it..In.case.of.sensors.carried.on.aircraft,.the.observations.from.GPS.and.INS.instruments.are.integrated.in the.piecewise.polynomials.and.are.corrected.from.constant.shifts.ans.misalignments.between.the.GPS.and.INS.local.systems.and.the camera.one.and.systematic.errors. contained.in.the. observations..A. self-calibration. is. also.included.for. the.corrections. of.radial. and decentering.lens. distortions,. principal. point(s). displacement,. focal. length(s). variation. and. CCD. line(s). rotation. in. the. focal. plane. Using. a. minimum. of. 6. Ground. Control. Points. (GCPs). and,. additionally,. Tie. Points. (TPs),. the. external. orientation. and. self- calibration.parameters,.together.with.the.TPs.ground.coordinates,.are.estimated.in.a.least-square.adjustment. In. order. to. demonstrate. the. model. flexibility. and. potentials,. different. imagery. from. pushbroom. sensors. (TLS,. EROS-A1,. SPOT- 5/HRS,.ASTER,.MOMS-02,.MISR).have.been.oriented..In.this.paper.a.summary.of.the.results.obtained.are.presented.and.discussed
