Description

technical field [0001] The invention belongs to a remote sensing device, in particular to a device and method for stabilizing the attitude of a remote sensing device and acquiring its outer orientation elements. Background technique [0002] When the remote sensing equipment is working on the aircraft, due to the influence of the airflow and the fuselage, the whole system is always in motion. If there is no gyro-stabilized platform to provide a stable environment for the remote sensing equipment, the remote sensing equipment can work on a stable boresight pointing and heading , will increase the cycle of aerial remote sensing and cause difficulties for later data processing; if there is no positioning and orientation system to provide high-precision position and attitude data for remote sensing equipment, the accuracy of aerial remote sensing will be reduced and the difficulty of later data processing will be increased. In addition, the gyro-stabilized platform, positioning ...

[0002] When the remote sensing equipment is working on the aircraft, due to the influence of the airflow and the fuselage, the whole system is always in motion. If there is no gyro-stabilized platform to provide a stable environment for the remote sensing equipment, the remote sensing equipment can work on a stable boresight pointing and heading , will increase the cycle of aerial remote sensing and cause difficulties for later data processing; if there is no positioning and orientation system to provide high-precision position and attitude data for remote sensing equipment, the accuracy of aerial remote sensing will be reduced and the difficulty of later data processing will be increased

In addition, the gyro-stabilized platform, positioning and orientation system, and remote sensing equipment are three different types of equipment that need to be operated separately. If methods cannot be adopted to simplify the operation process, it will increase the difficulty of the operator's work and cause confusion, which will affect the operation of the remote sensing machine. the quality of
