1738 results about "Broom" patented technology

A broom is a cleaning tool consisting of usually stiff fibers (often made of materials such as plastic, hair, or corn husks) attached to, and roughly parallel to, a cylindrical handle, the broomstick. It is thus a variety of brush with a long handle. It is commonly used in combination with a dustpan.

Calibration method of on-orbit optical distortion parameters of linear array push-broom camera

ActiveCN103673995AMeet the needs of on-orbit geometric internal calibrationRemove image distortionPicture taking arrangementsPhotographySatellite imageGeometric modeling
The invention discloses a calibration method of on-orbit optical distortion parameters of a linear array push-broom camera. The method comprises the following steps: firstly, collecting and obtaining dense high precision control point information by adopting an automatch algorithm based on control points, secondly, establishing strict imaging geometric models of all the control points, thirdly, computing the theoretical steering vector and the practical steering vector of each control point, and establishing an internal orientation element geometric calibration mathematical model of the camera, fourthly, establishing a distortion polynomial model, in which the theoretical steering vectors correspond to image column numbers, and fifthly, solving an error equation through a least square method, and performing iteration solving, so as to obtain internal optical distortion calibration parameters of the camera. The method calibrates internal optical system distortion of the satellite on-orbit camera by selecting a large number of high-precision ground control points, calibration results can be used for improving the uncontrolled positioning precision and the controlled positioning precision of satellite images, after internal orientation elements of the camera are corrected through internal distortion parameters, internal distortion of the images is basically eliminated.

Attitude compensation method of agile satellite imagery in reverse push-broom mismatch

ActiveCN102229362ASolve task planning and scheduling problemsImprove mission performanceImage analysisSpacecraft guiding apparatusEarth's rotationBroom
The invention discloses an attitude compensation method of agile satellite imagery in reverse push-broom mismatch. Aiming at the defect (only considering the drift current effect brought by earth rotation) of the attitude compensation method in the traditional imagery mode (the satellite directing over the ground is fixed), through analyzing the generation reason of a drift angle under the imagery mode of constantly changing satellite reverse push-broom attitude directing over the ground (constantly changing attitude directing over the ground under the condition of mismatch between the substellar point speed and the camera push-broom speed), the drift current effect of imagery is considered from three aspects (orbital motion, earth rotation and camera push-broom speed), a drift current angle calculation formula under the mode is obtained according to the orbital attitude parameters combining the basic definition of the drift angle, on the basis, the satellite attitude compensation method is obtained by combining the basic principle of TDICCD (time delayed and integration charge coupled device) imagery and the yaw control principle, and the imagery requirement of agile satellite reverse push-broom can be satisfied.
