Abstract

The invention provides a three-shaft inertial stabilization platform. The three-shaft inertial stabilization platform includes a pitch shaft assembly including a pitch frame, a pitch shaft and a pitchbearing, a roller shaft assembly including a roller frame, a roller bearing and a roller shaft, and an azimuth shaft assembly including an azimuth base, an azimuth bearing and an azimuth shaft, wherein the pitch bearing is mounted between the pitch shaft and the roller frame, the pitch frame and the pitch shaft are connected through a fastener, the roller bearing is mounted between the azimuth shaft and the roller frame, the azimuth bearing is mounted between the azimuth base and the azimuth shaft, and a standard interface universal transition board for meeting different types of sensors is mounted on the pitch frame. The three-shaft inertial stabilization platform is advantaged in that through mounting the universal transition board on the pitch frame, interchange of multiple types of sensors is realized, and universality of the multiple types of sensors is satisfied.

Description

technical field [0001] The invention relates to the technical field of aerial remote sensing, in particular to a three-axis inertial stabilization platform. Background technique [0002] Video and image sensors are widely used in military reconnaissance, space remote sensing, disaster forecasting, resource detection and other fields as fast and intuitive access to information. When the sensor is working, it is affected by factors such as attitude changes, vibrations, and airflow disturbances of moving carriers such as aircraft, which inevitably produces boresight shaking, which affects system imaging performance. In the field of aerial remote sensing, the inertial stabilization platform is used to compensate the attitude changes of the aerial platform in the three directions of azimuth, pitch, and roll to ensure that the optical remote sensing load can work in a better imaging environment, thereby improving the quality of remote sensing data acquisition. [0003] The inerti...
