Abstract

The present invention is applicable to the field of optoelectronic technology, and provides a three-axis inertial stable platform. The three-axis deceleration transmission system adopts a flexible cable transmission mode, and the rigidity of the flexible cable transmission can reach more than 10 times that of the same precision gear transmission or harmonic system. At the same time, it has the characteristics of high precision, low noise, smooth transmission, no lubrication, easy installation and maintenance, etc. The high rigidity and no backlash characteristics of the flexible cable precision transmission can ensure the fast dynamic response of the stable tracking servo system and improve the dynamic pointing accuracy of the platform.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and in particular relates to a three-axis inertial stable platform. Background technique [0002] Aerial photography is an important tool for resource exploration, geological analysis, and military surveying and mapping. When installing a camera or video camera on an aircraft for remote sensing imaging, due to the influence of factors such as aircraft vibration and aircraft yaw, roll, and pitch movements, it will cause blurring, distortion, and rotation of the remote sensing image, seriously affecting the shooting effect, and even causing Images are difficult to use. In order to effectively compensate the impact of aircraft vibration and angular motion on camera equipment and improve the quality of aerial images, a platform that can accurately achieve three-axis gyro inertial stabilization is essential. [0003] In the prior art, such as U.S. Patent US5922039, Chinese Patents CN1305091A...
