Problems solved by technology

However, the current UAVs also have the problem of being easily affected by aerodynamic factors. During the shooting process of UAVs, the lens often shakes due to the shaking of the fuselage, which leads to unclear shooting pictures, especially when "fine "In the case of images, the impact of this shake is more serious, which makes the simple camera system of traditional drones unable to meet people's requirements.

Embodiment 1

[0032] Example 1 ： Such as figure 1 As shown, the present embodiment provides an image acquisition system based on an unmanned aerial vehicle, including a controller, an attitude sensor, a three-dimensional attitude adjustment device, and a camera device; and the camera device connection;

[0033] The attitude sensor is used to sense the attitude change of the drone, and transmit the sensed attitude change information of the drone to the controller;

[0034] The camera device is fixedly arranged on the three-dimensional attitude adjustment device;

[0035] The controller is used to control the three-dimensional attitude adjustment device according to the received UAV attitude change information, so that the direction and angle faced by the lens of the camera device remain unchanged. Specifically, when taking pictures, the UAV The fuselage tilts to the x direction, and the attitude sensor senses the change of the drone fuselage for the first time, and sends the change in...

Embodiment 2

[0039] Example 2 ： The present invention also provides an unmanned aerial vehicle, which includes the above-mentioned unmanned aerial vehicle image acquisition system. When taking pictures, it can adjust the attitude of the imaging device according to the change of the attitude of the unmanned aerial vehicle body, so that the imaging The direction and angle faced by the lens of the device are not affected by the attitude change of the drone body and remain unchanged.

Embodiment 3

[0040] Example 3 ： Such as figure 2 As shown, the present invention simultaneously provides a kind of image acquisition method that can make the UAV airborne camera device unaffected by the change of fuselage posture when taking pictures, including the following steps:

[0041] S100: a step of receiving a photographing command;

[0042] S200: a step of sensing the attitude change of the drone body;

[0043] S300: A step of reversely adjusting the attitude of the lens of the camera according to the change of the attitude of the drone, so that the direction and angle facing the lens of the camera remain unchanged.

[0044] Wherein, the step of sensing the attitude change of the UAV body can be started after the UAV receives the photo command, or it can be sensed all the time regardless of whether the UAV receives the photo command.

[0045] In this embodiment, the attitude of the camera lens is directly adjusted by the three-dimensional attitude adjustment device to complet...

Abstract

The invention relates to the field of unmanned aerial vehicle control, and particularly relates to an unmanned aerial vehicle based image acquisition system, an image acquisition method and an unmanned aerial vehicle. The unmanned aerial vehicle based image acquisition system comprises a controller, an attitude sensor, a three-dimensional attitude adjustment device and a camera device. According to the unmanned aerial vehicle based image acquisition system provided by the invention, the high-sensitivity three-dimensional attitude adjustment device is arranged, and the camera device is fixedly arranged on the three-dimensional attitude adjustment device; and body attitude variations of the unmanned aerial vehicle when being photographed are sensed, a lens of the camera device is enabled not to be affected by the body attitude variations of the unmanned aerial vehicle through automatically adjusting the three-dimensional attitude adjustment device, thereby being always kept at the same direction and the same angle, thus realizing the lens attitude stability of the camera device of the unmanned aerial vehicle, and ensuring the quality of images.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle control, in particular to an image acquisition system, an image acquisition method and an unmanned aerial vehicle based on an unmanned aerial vehicle. Background technique [0002] With the continuous development of information technology, whether it is the construction of digital cities, smart cities, emergency support services in the face of major natural disasters, or the use and monitoring of various resources, timely and detailed space is required Geographic information as support. Therefore, the demand for low-altitude, large-scale and high-resolution digital images in many industries is becoming more and more urgent, and the requirements for real-time, stability and effectiveness are getting higher and higher. [0003] Usually, the traditional method of obtaining large-scale digital image information mainly relies on satellite remote sensing and aerial photography. However, satellit...
