Abstract
Official abstract text for this publication.
A method for optimizing a flight speed of a remotely-sensed scan imaging platform. The method comprises: selecting a reference point; obtaining a remotely-sensed scan image in a reference point region, and processing data; and optimizing a flight speed of a remotely-sensed scan platform. By optimizing a movement speed of a remotely-sensed movement platform, the method can prevent a geometric dimension of a target in a remotely-sensed scan image from being distorted, so as to obtain a high-precision remotely-sensed image of a ground target; and the method can be used for airborne and satellite borne remotely-sensed images.
First claim

1 . A method for optimizing flight speed of a remotely-sensed scan imaging platform, characterized in that it includes the following steps: Step 1: Selecting reference points: selecting point A and point B on the ground as reference points, wherein the distance between point A and point B is L AB km; selecting the central point of the connecting line of point A and point B as a reference point C; selecting point D as another reference point to make the connecting line CD of point D and point C perpendicular to the connecting line AB of point A and point B, and the distance between point D and point C be L CD km; Step 2: Obtaining a remotely-sensed scan image in a reference point region, and processing data; Step 3: Optimizing the flight speed of the remotely-sensed scan imaging platform. 2 . The method for optimizing flight speed of a remotely-sensed scan imaging platform according to claim 1 , characterized in that “Step 2: Obtaining a remotely-sensed scan image in a reference point region, and processing data” further includes: using a remotely-sensed scan platform to carry a remote sensing camera to obtain the remotely-sensed images A′, B′, C′ and D′ of reference points A, B, C and D at a movement speed V; and calculating the distance between A′ and B′ in the remotely-sensed images as L A′B′ pixels, and the distance between C′ and D′ as L C′D′ pixels. 3 . The method for optimizing flight speed of a remotely-sensed scan imaging platform according to claim 1 , characterized in that “Step 3: Optimizing the flight speed of the remotely-sensed scan imaging platform” further includes: calculating the optimized movement speed V′ of the remotely-sensed scan platform by using the movement speed V of the remotely-sensed scan platform, distance L A′B′ between A′ and B′ in the remotely-sensed images, distance L C′D′ between C′ and D′, distance L AB between point A and point B and distance L CD between point D and point C according to the formula of V ′ = V · L AB · L C ′ D ′ L CD · L A ′ B ′ .
