Tri-axial gyro stable seat frame

Abstract

The invention relates to an onboard air-survey camera gyro stable seat frame, in particular to a tri-axial gyro stable seat frame. A seat frame orientation ring is arranged in a pitching ring through an orientation ring bearing, and the orientation ring can rotate relative to the pitching ring. Pitching ring bearings are arranged on the left and right sides of the pitching ring symmetrically, the pitching ring is arranged in a rolling ring through the pitching ring bearings arranged on the left and right sides symmetrically, and the pitching ring can rotate relative to the rolling ring with the axis of the pitching ring bearings arranged on the left and right sides symmetrically as the rotation line. The rolling ring and a base are of an annular structure. Rolling ring bearings are arranged on the front and rear sides of the rolling ring symmetrically, the rolling ring is arranged in the base through the rolling ring bearings arranged on the front and rear sides symmetrically, and the rolling ring can rotate relative to the base with the axis of the rolling ring bearings arranged on the front and rear sides symmetrically as the rotation line. The tri-axial gyro stable seat frame isolates the low-frequency rocking of an aerial carrier, keeps an air-survey camera stable, overcomes the influences of airflow and other interference factors on aerial photography, and improves the aerial photography quality and efficiency.

Description

technical field [0001] The invention relates to a gyro-stabilized mount for an airborne aerial surveying and mapping camera, in particular to a three-axis gyro-stabilized mount. Background technique [0002] The aircraft will be affected by the aircraft itself and the airflow during flight photography, and it is difficult to keep the aircraft body stable, which brings great difficulties to high-precision aerial photography. Therefore, in the process of aerial photography, it is necessary to stabilize the camera system for aerial surveying and mapping, to keep the camera system stable horizontally (pitch and roll directions) and yaw angle (azimuth direction) and track during the aerial survey, so as to ensure The airborne aerial mapping camera takes high-precision shots of the designated area. Contents of the invention [0003] In view of the above prior art, the purpose of the present invention is to provide a three-axis gyro-stabilized mount to solve the problem of stabi...
