Panoramic photographing method for unmanned aerial vehicle and unmanned aerial vehicle using the same

Abstract

The invention relates to a panoramic photographing method for an unmanned aerial vehicle and an unmanned aerial vehicle using the same. The method comprises the following steps of: configuring a digital camera on an unmanned aerial vehicle; when a panoramic photo is executed, recording the flight attitude and the flight angle of the unmanned aerial vehicle when the photo is shot every time; performing a map connecting program, determining the image overlapping region of two photos according to the flight attitude and the flight angle of the unmanned aerial vehicle, and dividing a characteristic operation region; and performing a feature operation in the image overlapping area of the two photos to determine the image joint position, thereby generating a panoramic photo. The panoramic photographing method for the unmanned aerial vehicle and the unmanned aerial vehicle using the same can perform panoramic shooting with less calculation amount and lower calculation power without connectingpictures at a control end.

Description

technical field [0001] The present invention relates to a technology of an unmanned aerial vehicle, and more specifically, the present invention relates to a panoramic photographing method of an unmanned aerial vehicle and an unmanned aerial vehicle using the same. Background technique [0002] Unmanned aerial vehicles are unmanned aerial vehicles that can serve many fields such as land, surveying and mapping, forestry, transportation, water conservancy and military. The flight control device of the unmanned aerial vehicle mainly performs the flight attitude calculation, flight route control, and flight data feedback of the UAV, and performs related flight tasks during the flight. From the perspective of structural division of labor, the flight control system is the unmanned aircraft. The action center of the drone, its stability determines the safety of the drone's entire flight process. [0003] The most widely used application of unmanned aerial vehicle at present is to ...

Problems solved by technology

[0005] In the existing patents, most of the panoramic images need to be positioned with a satellite positioning system (GPS) to know the relationship between adjacent images to facilitate the subsequent image connection process. This method is limited to the shooting of outdoor panoramic and bird survey images. not able to use interior space

Generally speaking, the range of the comparison operation includes almost 80% of the entire photo, so it is quite computationally intensive.

If the processor of the digital camera on the unmanned aerial vehicle is not strong enough, it may be difficult to take panoramic shots

[0006] Therefore, in most of the technologies, such as (CN 104574278B), the captured image is sent back to the terminal for connection through wireless transmission, and in the patent (CN 105611170A), it is advertised that the realization of connection on the unmanned aerial vehicle is realized, thereby avoiding wireless Transmission and the need to compress the shortcomings of images to obtain good quality, but the case did not mention how to use the characteristics of unmanned aerial vehicles to reduce the amount of calculation and reduce power consumption
