Modeling method and apparatus for influence of unmanned helicopter vibration on aerial survey pod imaging

Abstract

The invention provides a modeling method and apparatus for an influence of unmanned helicopter vibration on aerial survey pod imaging. The method comprises the steps of determining a vibration source of an unmanned helicopter through characteristics of the unmanned helicopter and constructing a vibration model of the unmanned helicopter based on the vibration source; based on a mounting position of an aerial survey pod on the unmanned helicopter and an abated effect of a shock absorption system of the aerial survey pod on the vibration source, determining a vibration model of the aerial survey pod; determining a situation of vibration of a camera in the aerial survey pod along with the aerial survey pod through the vibration model of the aerial survey pod, and determining a degree of camera defocusing caused by vibration of the aerial survey pod; and based on the degree of camera defocusing caused by the vibration of the aerial survey pod, establishing a model of the influence of the vibration on the imaging quality of the aerial survey pod. According to the modeling method and apparatus for the influence of the unmanned helicopter vibration on the aerial survey pod imaging, provided by the invention, the image simulation can be accurately performed, so that the imaging quality is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned helicopters, in particular to a modeling method and device for the influence of unmanned helicopter vibration on aerial survey pod imaging. Background technique [0002] With the gradual progress of technology, unmanned helicopter has been developed rapidly, and it is becoming the focus of people's attention day by day. Because of its advantages of vertical take-off and landing, hovering in the air, flying in any direction, and small take-off and landing sites, unmanned helicopters have a large number of civilian applications, such as atmospheric monitoring, traffic monitoring, resource exploration, power line inspection, forest fire prevention etc. Each of the above applications is based on an unmanned helicopter carrying an aerial survey pod. During the operation, the aerial survey pod will inevitably be affected by the vibration from the unmanned helicopter, which causes the image position t...
