Abstract

The present invention provides a scanning method of a photoelectric remote sensing system, comprising the following steps: S10, providing a photoelectric remote sensing system suspended in the air, the photoelectric remote sensing system includes a hovering device, a pan platform arranged on the hovering device, and a The shooting device on the camera; S20, the camera is driven by the pan / tilt to scan the target area along multiple concentric circular trajectories; and the camera is driven by the pan / tilt to switch between multiple concentric circular trajectories, so that the The scanning area covers the entire target area, and the optical parameters of the shooting device are adjusted while switching the circular trajectory so that the spatial resolution of the pictures taken at all scanning points is the same. The object of the present invention is to provide a scanning method for a photoelectric remote sensing system, which can ensure that the scanning area completely covers the target area and make pictures taken at different target points have the same spatial resolution.

Description

technical field [0001] The invention relates to a scanning method of a photoelectric remote sensing system. Background technique [0002] In today's application of airborne photoelectric pods, etc., it is mainly to use the maneuvering of the carrier to take pictures of the vertical area directly below in real time, and it has not yet involved the scanning and observation of a large area of ​​the ground by the pod in a state of static suspension in the air. The commonly used scanning method at this stage is to scan with a rectangular trajectory. This method is due to the fact that the distance of each adjacent position relative to the pod is constantly changing. Therefore, parameters such as angle and lens focal length need to be controlled at the same time during the scanning process to ensure that parameters such as the resolution of photos taken at adjacent points match. Therefore, this solution is difficult to control, requires high control precision, and is prone to er...
